It seems that Paul Feig has a new muse and her name is Melissa McCarthy. While she has been on the CBS show Mike and Molly for awhile, it was her comedic turn in Bridesmaids that solidified her star status. In this film, she teams up with Sandra Bullock for a police buddy comedy. I'm not sure how to categorize McCarthy's character other than to say "chick is cah-razy". Bullock, plays a straight-laced FBI agent who I think we can all assume is eventually "loosened up" by her buddy.
There doesn't look to be anything too profound, but there are several laugh-out-loud moments in the trailer and that is more than I can say for most comedies these days.
