There's a movie in which the lead guy knows what exactly's going to happen... He is living that day for the second time, when he can set it all right... He knows his girlfriend is going to die of a car accident... And so he makes that day really special for them both... I think he dies at the end instead of his girlfriend...

I can't think of the name of this movie nor the actors or other details... It's a love story, I believe... Please let me know if you know the name... I've missed the end, and really want to watch it.

Thanks heaps :) :)

It's that christmas movie with Charlotte from sex and the city! The guys name is andrew in the movie and hers is beth. He takes her place to die, but ends up living too!

Is it "IF ONLY"?
Summary:
