Bridesmaids star Melissa McCarthy is back on the big screen with her latest comedy flick. In a new trailer released today, McCarthy robs a fast food joint with a paper bag over her head, Coolio's "Gansta's Paradise" providing the soundtrack.

The trailer is actually a teaser for McCarthy's latest flick, Tammy. According to E! Online, the comedy flick kicks off with McCarthy hitting the road with her rowdy grandmother, played by the legendary Susan Sarandon, after she finds out her husband has cheated on her, her car has been totaled, and and she gets fired from her job during the course of one day.

In the teaser, McCarthy hops out of her car and makes her way into the fast food joint, a paper bag wrapped around her right hand in what appears to be a gun. As she tries to make her way over the counter, she fails a couple times before she gets over and demands that they give her all the money...and some pie. She then makes them hide in their walk-in freezer, warning them to not try anything, before trying (and failing) to lock the door with a wooden spoon.

The film was penned by McCarthy and husband Ben Falcone, whom is also directing the comedy.

Tammy also stars Allison Janney, Gary Cole, Kathy Bates, Sandra Oh, Toni Collette and Dan Aykroyd. The film is set to hit theaters on July 2.
