Like screenwriter Dean Craig's previous film, Death at a Funeral, this (mainly) Australia-set comedy is set against the backdrop of a social function featuring a lot of people, in this case a wedding. Unfortunately, and also like the earlier movie, it's a largely unfunny blend of frantic farce and gross-out humour. Xavier Samuel plays a young Londoner who heads Down Under with his three best friends (Kris Marshall, Kevin Bishop and Tim Draxl) to marry the Aussie backpacker (Laura Brent) he fell for on holiday. However, a series of unfortunate mishaps and accidents involving a prize ram, a stash of cocaine and a vengeful drug dealer threaten to derail the glitzy wedding being thrown by Brent's disapproving politician father (Jonathan Biggins). Despite the accomplished playing of talented comic performers such as Marshall, Bishop and Rebel Wilson - plus an unexpectedly naughty turn from Olivia Newton-John as the bride's mother - director Stephan Elliott (The Adventures of Priscilla, Queen of the Desert) struggles to bring any zip to Craig's plodding, episodic script; even the bad-taste gags are rather half-hearted.
