Sandra Bullock and Melissa McCarthy can do no wrong. In fact, the only way they can do wrong is if their characters are doing wrong. And they appear to be doing a lot of that in Paul Feig's buddy-cop comedy The Heat. McCarthy is a tough police detective willing to do anything to get her man, including literally throwing the book at him, while Bullock is a tad more straight-laced. These new clips released from the 20th Century Fox film give you a taste of what to expect.
