The New 'Tammy' Trailer Proves Melissa McCarthy Will Win Fourth Of July Weekend

Warner Bros.

We saw the first teaser for "Tammy" back in February, but the full trailer shows us so much more. Melissa McCarthy plays Tammy, who robs a fast-food chain while wearing a paper bag, and now we find out she's on the run with her hammered grandmother (hey, Susan Sarandon!). Directed by McCarthy's husband, Ben Falcone ("Bridesmaids"), "Tammy" also stars Dan Aykroyd, Allison Janney and Kathy Bates. It hits theaters Fourth of July weekend, which is the perfect time to convince a fast-food employee to become your best friend so you can use their hot tub ... and wear crocs with socks.
