I will start by saying that I have read the book and it is one of my all-time favorites. The movie stuck pretty close to the book, right down to several quotes taken from the book. There were a few changes that surprised me. For example, in the book, Miles is a mild mannered person. In the movie, he's extremely bitter because of what happened to him due to his immortality. (Sorry, no spoilers) It was a good change.
The casting was amazing. Alexis Bledel plays Winnie Foster. Like Rory on Gilmore Girls, Winnie is very serious, but wants to have fun. William Hurt didn't strike me as someone old and wise, but he portrays Angus Tuck very well. Sissy Spacek was great as Mae Tuck, showing her character's motherly side toward Winnie.
Ben Kingsley plays the Man in the Yellow Suit (TMITYS). TMITYS is a great villain in the same league as Lex Luthor. He has no superpowers, but his mere presence can send super humans (immortals) running for cover. In the book, he's a vague character. He doesn't even seem to be a villain until later in the book. All we know is that he wants to find the Tucks and their spring. In the movie, TMITYS is presented as a villain, and we find out more about what he wants and how he knows about the Tucks. Bravo, Mr. Kingsley!
One last thought... (I know I said 'no spoilers', so I'll be as discreet as I can.) Don't let the ending disappoint you. I told my cousin the end of the movie and she said it was a terrible ending. It wasn't terrible. One character just made a choice. I strongly recommend this movie to people of all ages.
