Patton Oswalt joins the <strong><em>Young Adult</em></strong> cast
Comedic actor Patton Oswalt has signed on for the new Jason Reitman movie Young Adult, with Patrick Wilson also in negotiations for a role.

The Los Angeles Times has the news, although it isn't clear which roles Patton Oswalt or Patrick Wilson will be playing. Jason Reitman is directing from a script by his Juno screenwriter Diablo Cody.

Charlize Theron stars in the movie as a ghostwriter who returns to her hometown to reconnect with old friends and an ex-boyfriend who wants nothing to do with her. We reported in August that Josh Brolin was in talks to portray the ex-boyfriend, but it still isn't clear if he has signed on or not.

The site also reports that the movie should be ready to start shooting within the next few weeks, although there is still one more major female role waiting to be cast.
