Sandra Bullock and Melissa McCarthy have signed on to star in an untitled buddy cop movie for director Paul Feig (Bridesmaids).

Parks and Recreation scribe Katie Dippold wrote the script, which centers on the unconventional partnership between a straight-laced FBI agent (Sandra Bullock) and an eccentric Boston cop (Melissa McCarthy).

Peter Chernin, Jenno Topping, and Dylan Clark are producing, although the project doesn't have a studio home as of yet.

No production schedule was released.
