Brian Austin Green

Green was born in Van Nuys, California, the son of Joyce and George Green. He has some Scottish ancestry. His middle name, "Austin", was added to differentiate himself from another actor when he joined the Screen Actor's Guild as a child.Prior to his role on Beverly Hills, 90210, Green had a recurring role for three seasons (1986–1989) on the CBS primetime soap opera Knots Landing, playing the role of Brian Cunningham, the son of Abby Cunningham Ewing (Donna Mills). He reprised his role in the television miniseries Knots Landing: Back to the Cul-de-Sac (1997). He appeared in the 1987 pilot of Good Morning, Miss Bliss as Adam Montcrief.

Producer Aaron Spelling stated that Green was cast as David Silver because of their similar personalities. The character was often scripted to reflect Green's own interests. As the series progressed, the character began to experiment with hip hop music and DJing, as did Green himself. In 1996, Green dropped "Austin" from his professional name and attempted a career as a rapper, releasing one album, One Stop Carnival, produced by The Pharcyde member Slimkid3. In the 1990s, Green was a guest star on Growing Pains, Parker Lewis Can't Lose, Melrose Place, Saved by the Bell: The College Years, Fantastic Four, Mad TV, Biker Mice from Mars, Malibu Shores, Sabrina, the Teenage Witch and Knots Landing: Back to the Cul-de-Sac.

Green appeared briefly in the multiple award-winning Showtime drama series Resurrection Blvd. as Luke Bonner (2001–2004), a police officer attending law school. He had a cameo on Hope & Faith where he met Megan Fox; they started dating in 2004. He appeared on the ABC sitcom Freddie (2005) starring Freddie Prinze, Jr. He was a guest star on The Twilight Zone, Las Vegas and CSI: Crime Scene Investigation. He also appeared alongside former 90210 cast member Ian Ziering in the Tony Scott film Domino as parodies of themselves.

Green appeared in a horror short called Grace, which was set around a miscarriage gone bad, and features Gilmore Girls actress Liza Weil as his love interest. It premiered at the Fangoria Weekend of Horrors on June 2, 2006, and was reworked as a full-length feature film (2009). He was a guest star on George Lopez in 2006 as Chris.

Green played Derek Reese in Terminator: The Sarah Connor Chronicles, a Resistance fighter sent to the past by the future John Connor. The character is the older brother of Kyle Reese (John Connor's father) and paternal uncle of John. Green was a recurring character in season 1 but became a regular at the start of season 2, following a positive response from critics and fans. His character is killed by a Terminator in the penultimate episode, but another Derek from an alternate timeline is introduced in the series finale and would have remained on the show if it had been renewed for a third season.

Green guest-starred on the season 7 finale of CSI: Miami as Anthony Green. Green was cast in The CW's new drama pilot Body Politic, along with Minka Kelly, Gabrielle Union, and Jason Dohring. The series was not picked up for fall 2009. Green said in an interview that he was co-producing a big screen adaptation of Fathom, starring Megan Fox. On September 27, 2009, Green made a guest appearance on the television series Saturday Night Live in a skit involving girlfriend (later his wife) Megan Fox. In the skit Green played a version of the Transformer Bumblebee in which Bumblebee is merely a man wearing a Bumblebee mask. Green was cast as Clay in One Tree Hill's seventh season. Green then left the cast because of scheduling conflicts and the role was then given to Robert Buckley; Green instead starred as superhero Callan in the Patrick Durham-directed movie Cross, which was released to DVD and download in May 2011.

In 2009, Green was cast as Metallo in Smallville. He appeared in three episodes in the ninth season between 2009 and 2010, the first being the ninth-season premiere episode "Savior". The character is a war-time reporter, similar to the Silver Age John Corben. As a back-story for this version, he had been recently stationed in Afghanistan. When he meets Lois Lane, he expresses his distaste for vigilantes, particularly "the Blur" (Clark Kent) due to the hero saving a prison bus only for a convict to escape and slay his sister. After being struck in a hit and run, Corben awoke to find himself possessing cybernetic enhancements - including an artificial heart powered by kryptonite. After kidnapping Lois Lane as bait, the villain was confronted and defeated by Clark Kent. It was subsequently revealed in the episode "Conspiracy" that Zod's disciples were behind Corben's revival. Corben is "reactivated" in the episode "Upgrade" after Luthorcorp scientists are able to correct the initial design flaw in the Kryptonite heart that causes an adrenal overload and resulting psychosis. Though Green had expressed willingness to reprise the character in the 10th and final season, the character was portrayed by a body double for his final appearance in the episode "Prophecy" - presumably due to budget and the cameo nature of the appearance. Green's likeness would be used however for the character's appearance in the Season Eleven comic continuation.

In 2010, Green appeared in a multi-episode story arc on the ABC series Desperate Housewives. He played Keith Watson, Bree's contractor and lover for the first part of the season.

In 2012, Green had a guest appearance in the sitcom Anger Management playing Sean, the boyfriend of Charlie's ex-wife, Jen in the first episode of the show. This episode broke a ratings record with 5.74 million viewers on its series debut night and ranks as the most-watched sitcom premiere in cable history. He returned to the show in the episode "Charlie Breaks Up With Kate", and was promoted to series regular in June 2013.

Green was a guest star in the finale episode of the second season of Happy Endings. He played Chris, who meets dateless Penny via Skype. He returned in the third-season premiere "Cazsh Dummy Spillionaires". In the same year, Green starred in the television series Wedding Band, about a group of friends who perform at weddings. In the TBS comedy, Green plays Tommy, the frontman for Mother of the Bride, a group of four buddies who aren't ready to give up the dream of being rock stars. On January 22, 2013, TBS cancelled the series after one season because of low ratings.

In 2020, Green competed in season four of The Masked Singer as "Giraffe". He was eliminated in his second appearance. Robin Thicke joined him in his encore of Kool and the Gang's "Get Down on It". He also served as a panelist on its spin-off series The Masked Dancer. In 2023, Green competed on the fifth season of the Australian version of The Masked Singer as "Crash Test Dummy". He was eliminated in the premiere episode.

In September 2021, Green was announced as one of the celebrities competing on season 30 of Dancing with the Stars. Green's dance partner was his girlfriend, Sharna Burgess. He was the third celebrity to be eliminated from the show, ultimately placing 13th.
