When the women of Bridesmaids board a plane bound for a bachelorette party in Vegas, it’s easy to assume that’s where the movie’s really going to get crazy. By this point in the narrative, the characters in this group have already been established as an idiosyncratic and wide-ranging set of personalities. Rather than making them a band of lifelong friends, writers Kristen Wiig and Annie Mumolo choose to make them strangers, only bonded by their independent friendships with the bride-to-be, Lillian (Maya Rudolph). The personality clashes and getting-to-know-you moments provide the basis for a lot of the initial comedy within that group dynamic; as the flight takes off for Sin City, the possibilities for disastrous hilarity seem set.
