Melissa McCarthy may well have another box-office success on her hands with "Tammy" -- helmed by her husband Ben Falcone -- and hitting theaters over the July 4 weekend. A new trailer has arrived for the comedy, which follows a bumbling fast-food restaurant robber (McCarthy), and the on-the-lam road trip she embarks upon with her mother (a de-glammed Susan Sarandon). Watch below.
As per usual, there's plenty of gags involving McCarthy's physicality and her inimitable line delivery. The actress has proven herself a bankable headliner over the past three years, stealing the show in 2011's "Bridesmaids," and then delivering two hit comedies last summer -- the poorly reviewed "Identity Thief" opposite Jason Bateman, and Paul Feig's "The Heat," where McCarthy was one of an odd-couple police duo with mega-star Sandra Bullock.
