'Bridesmaids' Trailer: Kristen Wiig, Maya Rudolph In New Trailer (VIDEO)

The Judd Apatow-produced comedy 'Bridesmaids' has gotten positive buzz coming out of SXSW, and now a new trailer is out.

The plot feels familiar - an unhappily single woman (Kristen Wiig) must serve as maid of honor for her best friend (Maya Rudolph) - but there might be enough potty humor and gymnastic sex (including that between Wiig and Jon Hamm, sadly absent from the trailer) to make it a hit. Ellie Kemper, Melissa McCarthy, Matt Lucas, Jill Clayburgh and Rose Byrne round out an excellent supporting cast, and 'Freaks and Geeks' creator Paul Feig directs.

'Bridesmaids' opens May 13.
