Jason Reitman (Juno, Up in the Air) is once again assembling an interesting mix of actors for his next movie. For the director is working to get Patrick Wilson to play the male lead opposite Charlize Theron for Young Adult. No deal is yet in place but negotiations are under way. The film, from Juno screenwriter Diablo Cody, centers on a thirty-something, divorced young adult fiction writer who returns to her hometown to chase the ex-boyfriend that got away. Only problem? He’s married with a child. Wilson would of course play said ex-boyfriend.

Probably best known for his roles in Todd Field’s Little Children and Zach Snyder’s Watchmen, Wilson was just in The A-Team and can next be seen in Morning Glory, the upcoming news comedy which stars Harrison Ford and Rachel McAdams. Comedian Patton Oswalt is also looking to join the group, as a self-hating man who was in love with Theron’s character in high school.

Young Adult is being produced by the Juno team of Mandate Pictures and Mr. Mudd Productions. Paramount Pictures is negotiating to distribute the film. They are the studio behind Reitman’s 2009 film Up in the Air. Production is set to begin in this fall.
