Rebel Wilson and Olivia Newton-John deliver massive laughs in this wickedly funny comedy about supporting your best friends "for better or for worse." When David unexpectedly gets engaged during a whirlwind vacation, his best friends are determined to send him off into married life in signature style. But when they arrive in Australia, the nuptial plans go from bad to worse as the guys discover that unpredictable relatives, a cross-dressing sheep and a deranged drug dealer don't necessarily equate to a match made in heaven. It's going to be a day no one will forget in this hilarious film from the acclaimed director of The Adventures of Priscilla, Queen of the Desert. © 2011 Universal Studios. All Rights Reserved.
