EXCLUSIVE: Sony Pictures is setting Patton Oswalt, Bob Oedenkirk and Ian Roberts to round out the cast of Kitchen Sink, the genre mash-up that stars Nicholas Braun, Mackenzie Davis, newcomer Josh Fadem, Joan Cusack Keegan-Michael Key, Ed Westwick, Vanessa Hudgens and Denis Leary. The pic, directed by Robbie Pickering from a script by Oren Uziel, is just getting underway in Los Angeles. Matt Tolmach is producing with Ron Schmidt and Jonah Hill exec producing.

The action takes place in Dilford, a place where vampires were at the top of the social order, zombies were at the bottom, and the humans were in the middle. This all goes awry and it’s a battle, and it’s up to three reps of those groups to restore harmony. Said Tolmach: “Kitchen Sink has all the chaos and carnage of a classic genre movie, but at its heart it’s a comedy about three kids just trying to survive the pain and awkwardness of high school, where every day feels apocalyptic.”
