Actor Thomas Mann (It’s Kind of a Funny Story) is in final negotiations to join two upcoming projects. First up, the actor is in talks to star alongside Victoria Justice (TeenNick’s Victorious) in Fun Size. Marking the feature directorial debut of Josh Schwartz (creator/executive producer of Chuck, Gossip Girl), the film tells the story of a teenage girl who loses her younger brother trick-or-treating on Halloween. Variety reports that Mann will play Roosevelt, “the star of his school’s debate team who is in love with Justice’s character, Wren.” He aids Wren in the search for her brother. Max Werner (The Colbert Report) wrote the script.
