Newly svelte Jonah Hill (almost unrecognizably so) has been formally set to star alongside Ben Stiller and Vince Vaughn in Neighborhood Watch, the Akiva Schaffer-directed Fox comedy. Shawn Levy is producing through his 21 Laps banner. Hill will next be seen starring opposite Brad Pitt in Moneyball, which premieres next month at the Toronto Film Festival, and he stars in the David Gordon Green-directed Fox comedy The Sitter. He’ll look like a different actor in Neighborhood Watch, because you can see he has slimmed down quite a bit. He’s repped by WME.
