Kassius Lijah Marcil-Green is an American creative professional and celebrity family member best known as the son of actors Brian Austin Green and Vanessa Marcil. Born into a family closely connected with television and Hollywood, Kassius attracted public attention from an early age. In recent years, however, he has started developing an identity of his own through acting, writing, filmmaking, and other creative projects.
Kassius Lijah Marcil-Green often centers on his famous parents. Brian Austin Green became a household name through his portrayal of David Silver on Beverly Hills, 90210. At the same time, Vanessa Marcil is recognized for her performances in General Hospital, Beverly Hills, 90210, and Las Vegas.
Hollywood connections, Kassius has generally maintained a lower public profile than his parents. His growing entertainment credits nevertheless demonstrate an interest in storytelling both in front of and behind the camera.
Here is a detailed look at Kassius Lijah Marcil-Green, including his age, childhood, parents, siblings, emerging career, family background, and life today.
Who Is Kassius Lijah Marcil-Green?
Kassius Lijah Marcil-Green is the son of Vanessa Marcil and Brian Austin Green. He was born on March 15, 2002, making him 24 years old as of 2026.
Although he has been associated with Hollywood since birth because of his parents, Kassius has gradually started creating his own professional identity. His recent entertainment work has included acting and writing credits, particularly on independent and online-oriented productions.
He is sometimes referred to simply as Kassius Marcil-Green or Kass. While celebrity media coverage has frequently concentrated on his parents and their relationship, his own creative projects offer a different perspective on his developing career.
Kassius Lijah Marcil-Green Early Life
Kassius was born when both his parents were already established performers.
His father, Brian Austin Green, had achieved considerable fame through Beverly Hills, 90210. Vanessa Marcil had similarly established a successful acting career, particularly through her work on General Hospital.
Kassius’s parents met while working on Beverly Hills, 90210. Their relationship developed during the late 1990s, and they eventually became engaged. Kassius was born in 2002, but their relationship ended soon after.
As a result, much of Kassius’s childhood involved a family structure in which his parents lived separately.
Unlike many celebrity children who pursue highly public careers from a young age, Kassius was not constantly in the entertainment spotlight. This gave him the chance to develop his interests before building his own professional credits.
Who Is Kassius Lijah Marcil-Green Mother?
Kassius’s mother is actress Vanessa Marcil.
Marcil has enjoyed a lengthy career in American television. One of her best-known roles is Brenda Barrett on the long-running ABC soap opera General Hospital. Her performance earned her significant recognition, including a Daytime Emmy Award.
She also joined Beverly Hills, 90210 as Gina Kincaid. That series has an important place in Kassius’s family history because Brian Austin Green was already one of its major cast members.
Another significant part of Marcil’s television career came with Las Vegas, in which she portrayed Sam Marquez.
Although Vanessa Marcil’s professional achievements have made her a recognizable television personality, she has also occasionally discussed motherhood publicly. Kassius remains her only child.
Who Is Kassius Lijah Marcil-Green Father?
Kassius’s father is actor Brian Austin Green, who became internationally recognized for portraying David Silver on Beverly Hills, 90210.
Green appeared throughout much of the show’s original run and subsequently continued working across television and film. His later television credits have included productions such as Terminator: The Sarah Connor Chronicles and Anger Management.
Kassius is Brian Austin Green’s eldest child.
After his relationship with Vanessa Marcil ended, Green later married actress Megan Fox. Their marriage expanded Kassius’s family considerably because Green and Fox welcomed three sons together.
Green subsequently entered a relationship with professional dancer Sharna Burgess, and they also welcomed a son.
As a result, Kassius has several younger half-brothers on his father’s side.
Kassius Lijah Marcil-Green’s Parents Relationship
Brian Austin Green and Vanessa Marcil met through their involvement with Beverly Hills, 90210. Their relationship began around 1999, and they became engaged in 2001.
Their son, Kassius, was born in March 2002.
The couple ultimately separated in 2003 and never married.
Their relationship and later co-parenting situation have periodically received media attention. Both parents have made public statements over the years concerning their family history, sometimes presenting conflicting accounts.
Because many of those statements involve personal disagreements, they should be understood as claims made by the individuals involved rather than independently established descriptions of every aspect of Kassius’s childhood.
Kassius himself has generally been considerably less public about those disputes.
Kassius Lijah Marcil-Green Siblings
Kassius is Vanessa Marcil’s only child, but he has younger half-siblings through his father.
Brian Austin Green and Megan Fox welcomed three sons: Noah Shannon Green, Bodhi Ransom Green, and Journey River Green.
Green later welcomed another son, Zane Walker Green, with Sharna Burgess.
Kassius is therefore the oldest among Brian Austin Green’s five children.
The age difference between Kassius and his younger siblings is substantial. He was born in 2002, while his father’s other children arrived years later.
As the eldest child, Kassius holds a distinctive place in the extended Green family.
Kassius Lijah Marcil-Green and Megan Fox
Another well-known person connected to Kassius’s family is actress Megan Fox.
Brian Austin Green began dating Fox after his relationship with Vanessa Marcil had ended. Green and Fox eventually married in 2010.
Kassius was still a child at the time and reportedly participated in their wedding as Green’s best man.
Green and Fox subsequently became parents to Noah, Bodhi, and Journey, making them Kassius’s younger half-brothers.
Although Green and Fox later separated and divorced, Kassius remains connected to their children through his father.
Kassius Lijah Marcil-Green Career
For years, articles about Kassius described him mainly as the child of famous actors. That description is becoming increasingly incomplete as he develops his own creative credits.
Kassius has explored entertainment through acting and writing, including projects associated with comedian and filmmaker Brandon Rogers.
His career path is particularly interesting because it doesn’t simply replicate his parents’ careers. Instead of focusing exclusively on mainstream television, he has worked on independent, short-form, and digitally oriented productions.
This has given him opportunities to explore multiple aspects of storytelling.
Acting and Class Acts
One notable project associated with Kassius is Class Acts.
Kassius Marcil-Green received acting credits on multiple episodes of the series, portraying several characters. The project also allowed him to contribute beyond acting.
He received writing credits for episodes of Class Acts and was also credited for cinematography.
Those behind-the-camera roles matter because they show his interest in entertainment goes beyond performing.
Acting requires interpreting an existing character, while writing and cinematography involve different stages of creating the story itself. Experience across these areas can provide a more comprehensive understanding of filmmaking.
Working With Brandon Rogers
Kassius has worked on projects connected to Brandon Rogers, an actor, comedian, writer, director, and online content creator known for character-driven comedy.
This collaboration has given Kassius opportunities to participate in unconventional productions outside traditional Hollywood studio filmmaking.
For example, Kassius appeared as a security guard in the 2023 short You Can’t Film Here.
The role added another screen credit to his growing body of work and helped establish a pattern of collaboration that continued through later projects.
A Night at the Park
One of Kassius Lijah Marcil-Green’s notable creative credits is the 2025 short film A Night at the Park.
Kassius was credited as a writer on the project, demonstrating his growing interest in creating material rather than only appearing on screen.
He also received a cast credit.
Having both writing and performance involvement in the same production suggests a hands-on approach to entertainment. It also represents another step toward building a professional portfolio independent of his parents’ careers.
This Is NOT a Cult
Kassius also expanded his writing experience through the 2025 miniseries This Is NOT a Cult.
He received writing credits on multiple episodes alongside Brandon Rogers.
Writing for a multi-episode production differs from appearing briefly in an individual project because it requires contributing to a continuing story, characters, and overall creative direction.
Kassius was also associated with the related short, This Might Be a Cult, as a performer.
These credits strengthen the picture of a young creative professional who is exploring multiple roles within entertainment.
Kassius Lijah Marcil-Green as a Writer
Writing may become an increasingly important part of Kassius’s professional identity.
As the child of two successful actors, acting may have seemed like the most obvious career path. His recent credits, however, suggest that storytelling and production also interest him.
Writing offers a creative role that exists largely outside Hollywood’s celebrity-focused side.
It remains too early to know precisely where Kassius will ultimately concentrate his professional efforts. Nevertheless, the combination of writing, acting, and production-related experience gives him several possible directions.
Kassius Lijah Marcil-Green Personal Life
Kassius has generally maintained more privacy than his famous parents.
There has been online interest in his romantic life and sexuality, and he has previously shared aspects of his personal life publicly. Older media reports have discussed a relationship with Ian Ward.
However, personal relationships can change, and older reports should not automatically reflect his current relationship status.
This distinction matters, especially for individuals who don’t constantly document their private lives through mainstream celebrity media.
Rather than speculation about his relationships, his verified creative work provides a more reliable basis for understanding what Kassius is doing today.
Kassius Lijah Marcil-Green Net Worth
Searches for Kassius Lijah Marcil-Green frequently include questions about his net worth.
Various celebrity websites publish estimated figures, sometimes claiming that his wealth reaches millions of dollars. However, no reliable public financial documentation supports a precise personal net worth for Kassius.
Net-worth websites frequently calculate celebrity wealth using assumptions about income, property, investments, and career earnings rather than verified financial records.
For that reason, treat any specific Kassius Lijah Marcil-Green net worth figure as speculative unless reliable financial information becomes publicly available.
His parents have had lengthy entertainment careers, but their wealth should not be automatically attributed to Kassius.
How Old Is Kassius Lijah Marcil-Green?
Kassius Lijah Marcil-Green was born on March 15, 2002.
Therefore, he is 24 years old as of 2026.
Some online sources conflict about his birthday, with certain celebrity-biography websites listing a different March date. However, established biographical records associated with his parents support March 15, 2002.
Why Is Kassius Lijah Marcil-Green Famous?
Kassius initially became known because of his parents.
Being the son of Brian Austin Green and Vanessa Marcil naturally generated media attention, particularly because both actors were connected with Beverly Hills, 90210.
His father’s later marriage to Megan Fox further increased public curiosity about the extended family.
Today, however, Kassius has another reason to attract attention: his developing creative career.
His credits in acting, screenwriting, cinematography, and independent entertainment show he has begun building professional accomplishments separate from his parents.
Kassius Lijah Marcil-Green Today
As of 2026, Kassius is in his mid-twenties and has accumulated several recent entertainment credits.
Projects such as Class Acts, A Night at the Park, and This is NOT a Cult show show growing involvement in writing and screen entertainment.
It remains unclear whether he intends to focus primarily on acting, writing, filmmaking, or another creative field over the long term. His existing work indicates that he is comfortable experimenting with several roles rather than limiting himself to one area.
That makes the next stage of his career worth watching.
Instead of simply following the conventional path of a celebrity child entering mainstream Hollywood acting, Kassius appears to be gaining experience through smaller, more independently produced creative projects.
Interesting Facts About Kassius Lijah Marcil-Green

He has four younger paternal half-brothers.

Most importantly, his recent projects show a developing professional story separate from his famous parents’ relationships and careers.
Conclusion
Kassius Lijah Marcil-Green may have first attracted public attention as the son of Vanessa Marcil and Brian Austin Green. Still, his story is gradually expanding beyond his famous family background.
Born on March 15, 2002, Kassius grew up with direct connections to the entertainment industry. His mother became famous through productions including General Hospital, Beverly Hills, 90210, and Las Vegas, while his father achieved widespread recognition as David Silver on Beverly Hills, 90210.
Kassius nevertheless appears to be developing his own creative path. Acting credits introduced him as a performer, while projects including Class Acts, A Night at the Park, and This is NOT a Cult have demonstrated his interest in writing and other aspects of production.
His family connections will inevitably remain part of public interest surrounding his name, especially given the fame of Brian Austin Green, Vanessa Marcil, and Megan Fox. Yet focusing only on those relationships overlooks the most interesting recent development in his story.
As Kassius Lijah Marcil-Green continues building experience in entertainment, his identity is increasingly tied not simply to being the child of famous actors but to his own work as a developing writer, performer, and creative professional.
