Jason Segel (Forgetting Sarah Marshall) and Ed Helms (The Hangover) will star in a new stoner comedy titled Jeff Who Lives at Home. Segal will play Jeff (who lives at home with his mother) and is unmotivated to change his life. Helms will play the brother who is more successful but can be overbearing. It’s about time these two guys worked together. Especially on a stoner film.
