After last appearing on an ABC drama in 2009, actor T.R. Knight is returning to the network. The actor, who played George O’Malley on Shonda Rhimes’ first hit show Grey’s Anatomy, is returning to star in a new show that is being produced by Reese Witherspoon, according to The Hollywood Reporter.

The drama will be a divorce drama, which is described a divorce drama that “centers on Gemma, a ruthless Dallas divorce attorney whose life begins to unravel when her emotionally damaged, love-addicted sister resurfaces, triggering self-destructive tendencies and exposing long-hidden family secrets,” The Hollywood Reporter said.

The website also said that Knight’s character will play Mark, a character at the same law firm as Gemma who is up for the same promotion she is.

Knight’s Grey’s Anatomy character, George O’Malley, was one of the original cast members of the show and appeared in the first five seasons of the show. When a breakdown in communication occurred between him and Rhimes happened, he asked to be released from his contract. He also cited not getting much screen time in the past season and his decision to come out as gay as other reasons for leaving the show a season early.

His character was killed off in the season five finale, when he was hit by a bus and dragged 30 feet. In a scene reminiscent of the season two finale of the show, character Izzie Stevens (portrayed by Katherine Heigl), who was also dying, heads towards an elevator and sees O’Malley standing there. O’Malley ends up dying, but Stevens survives.

Heigl’s character left the show in the middle of the sixth season and hasn’t returned since. Rhimes is notorious for saying she will never work with Heigl again.

For his role on Grey’s Anatomy, Knight was nominated for an Emmy for Outstanding Supporting Actor in a Drama Series in 2007, though he lost to Terry O’Quinn for his role as John Locke on Lost.

Since leaving Grey’s Anatomy, Knight has guest-starred in numerous shows, including a guest-starring arc in season four of the CBS legal drama The Good Wife. He played Jordan Karahalios, a political consultant that steps in to help on Peter Florrick’s gubernatorial campaign. He is currently working on Hulu’s 11.22.63, which is based off of Stephen King’s novel of the same name. He has also been in the Broadway show It’s Only A Play. He also guest starred on an episode of Law and Order: Special Victim’s Unit.

While he’s guest starred and been a recurring star on different shows since leaving Grey’s Anatomy, this will be his first series regular role.
