After seeing Bridesmaids, audiences and critics who enjoyed the film tended to agree that Melissa McCarthy would be one of the breakout stars of the year.  That easy prediction is already coming true with McCarthy and Bridesmaids co-write Annie Mumolo selling a pitch to Paramount, and McCarthy being rumored to co-star with Jon Hamm in a new Paul Feig/Judd Apatow comedy.  McCarthy will certainly be working with Apatow again, but he'll be directing her in his untitled Knocked Up spin-off starring Paul Rudd and Leslie Mann.  THR reports that McCarthy will play a mom at the school where Rudd and Mann’s children attend and that Super 8 co-star Ryan Lee will play her son.The untitled comedy also stars Albert Brooks, Megan Fox, Chris O'Dowd, Lena Dunham, Charlene Yi, and Wyatt Russell.  The film is set to open in December 2012.
