Kristen Wiig, Melissa McCarthy and Rose Byrne, Bridesmaids (in theaters)
SNL standout Wiig (second from right) co-wrote and stars in this Judd Apatow-produced comedy as a down-on-her-luck baker enlisted to play maid of honor for her best friend's wedding. Mike & Molly's McCarthy (at left) and Damages' Byrne (third from left) play diametrically opposed bridesmaids, whose warring influences wreak havoc on Wiig's character. Bonus: Mad Men's Jon Hamm steals a few scenes as Wiig's friend with benefits.
