Bridesmaids (2011)

Annie is a 30-something whose best friend Lillian is getting married, and Annie is asked to be a bridesmaid. When Helen, a snobbish friend of Lillian's, comes up with all sorts of ideas and proposals and gets all the compliments, Annie is annoyed and jealous, accepting a sort of implicit challenge. An irreverent, acid comedy about friendship that pokes fun at snobbery, with a hilarious acting duel between Kristen Wiig and Rose Byrne.
