Terrified by the prospect of marriage, an English slacker Dennis Doyle (Simon Pegg) leaves his pregnant fiancée Libby (Thandie Newton) at the altar. Five years later, the lazy and paunchy Dennis attempts to win her back, impress their young son (Matthew Fenton), and stick it to Libby’s successful new American beau (Hank Azaria) by running in a London marathon--that’s only three weeks away. Dylan Moran co-stars in this delightful comedy; Davis Schwimmer directs. 100 min. Widescreen (Enhanced); Soundtrack: English.
