Ok but Sinise wasn’t an amputee at the beginning of the movie so that is a bad example. The laws of physics exist and it’s much easier to make a leg disappear on film than it would be to make an actual amputee appear to have fully functional legs. Besides the fact that he was an amputee was only one aspect of his character. I hope we don’t go down the path of characterizing an entire person based solely on their disability.
