Fox Searchlight brings three stars together for a Mark and Jay Duplass comedy. John C. Reilly, Jonah Hill, and Marisa Tomei will be teaming up for the yet untitled film.

The film tells the story of a recently divorced man (Reilly) who falls in love with a mother (Tomei) of a teenage son (Hill). The problem is that the son doesn't want to share his mother with the man.

The Duplass brothers will make their studio directorial debut on the film. Scott Free is producing. Production starts in January.

Tomei will next be seen in the Darren Aronofsky-directed film "The Wrestler," while Hill is shooting a new Judd Apatow film "Funny People." Reilly was last seen in the comedy "Step Brothers" with Will Ferrell.
