Anyway, according to IMDB, the movie is about a handsome, roguish, secretly romantic womanizer (is there any other kind in movies?) who is "haunted by the ghosts of his past girlfriends at his younger brother's wedding." It's kind of like a romantic comedy version of A Christmas Carol, but instead of the ghosts being conceptual -- Christmas Past, Christmas Future, etc. -- they're the ghosts of real people, women the character has ostensibly dicked over.
And here's where we run into the big problem in the story. A really big problem. Something, in fact, that I've been wondering about since this movie was first announced back in 2003.
Why are all his ex-girlfriends dead?
