Before You Say 'I Do' (2009)

George Murray's fiancée Jane Gardner gets cold feet after accepting his ring, terrorized by her first wedding with Doug, who cheated that very day with their wedding coordinator. After a car crash, George finds himself 10 years in the past, just days before Doug's day. And before he and his colleague-friend Harvey Blinton are to be cheated out of a brilliant career in advertising by sleaze-bag Jack Harrington. However, every change to the past starts a whole series, not necessarily for the better.
