I had to split this because I hit the length limit, and this was a pretty separate aspect of the reply:
Edmund's treachery
Ok, since it is possibly different, and I don't recall the book at all to do the comparison, let me spell out the details of that and of Aslan's sacrifice as they were in the movie, and you can compare:
In their initial encounter, the Witch offers Edmund the eventual kingship
Asking about Peter, Edmund's all "he wouldn't get to be king too, would he?"
The Witch is all, "no, no, you'd need servants".
Edmund is there for the reading of the Queen's proclamation about Tumnus' consorting with humans
They meet the Beavers and go to their place
Edmund sneaks out and goes to the Witch's
The follow and see him go in
She won't give him turkish delight until he reveals where the others are (I think those were linked, it's been a couple of weeks)
He reveals; she imprisons him
Everyone barely gets out of Beavers' in time, head for Stone Table
Witch asks Edmund where they were going, he says he doesn't know
Later, a fox (or something) who knows where they were going (I think) won't reveal, and Witch is about to kill him, and Edmund steps in and reveals the Stone Table destination. (Witch "kills" fox anyway, natch.)
Aslan sneaks off at night
Susan and Lucy follow
Aslan realizes they're following, asks them to accompany him (although I read this not so much as him wanting them to see as him figuring he can't stop them)
Aslan gets close (NOT in sight of Table) and tells them they can go no further
Susan leads Lucy up a hill until they end up with a view
etc.
Aslan appears to come back in maybe a day or so, not three.
One particular note (and I doubt this is actually different from the book), is that the Witch proposes the fantasy of Edmund's siblings being his servants, and he is happy with it and runs with it. Apparently we are supposed to think this is evil and bad, but the fantasy of all four kids being rulers with all the non-humans as their (essentially) servants: not bad or evil at all! Hooray!
