The teaser for Tammy, which we first saw back in February, showed Melissa McCarthy robbing a fast-food chain, wearing a paper bag of the same chain as a mask. In the full trailer, we get a look at the fallout of the, let's say, heist. Tammy is on the run, with her drunk grandmother (Susan Sarandon) keeping her company. McCarthy co-produced and co-wrote the film with her husband Ben Falcone, who also directed. The film opens nationwide on July 4 weekend, because what did the founding fathers fight for, if not the freedom to have hot tub best friends.
