I haven'tread the books but do like Tom Cruise so I will probably go see the movie. I read an interview with Lee Child who said TC was not his first choice but after he saw the movie, he did approve of him. So often the video depiction of books really changes them; for instance, Temperance Brennan, aka "Bones" is nothing like her counterpart in the books by Kathy Reichs. I think that was what was so amazing about the Harry Potter movies; the characters really looked liked the descriptions in the books and I loved that they stayed the course for all of the movies!
