I just bought the DVD of this, and I watched the Director's Cut of the movie on it. And the original ending is much more depressing.
(Spoilers)
In the Director's Cut, his mother and him visit a psychic while he's in college (just before Kaylie kills herself) and the psychic flips out, cuz Evan's got no life line and shouldn't even exist (good line though, on his part "if you're a psychic, you'll see this coming" as he takes back the money they paid her). His mother starts crying, and tells him that she was pregnant twice before, but they were stillborn.
The movie continues on without anymore major differences (except you find that his grandfather was also afflicated with the condition), until the very last time he goes into the past, while in the institution. Instead of a movie of when he first meets Kaylie, its a movie of his birth. So, he goes back to that and, as the doctors are carting his mother into the hospital (he's still in the womb), grabs onto the umbilical cord, killing himself.
So, he saves Kaylie, Tommy, and Lenny (his mother doesn't take it well though), but makes the ultimate sacrifice. You also realize that thats exactly what his potential siblings must have done as well.
Its a much more depressing ending.
