Yeah. The only part of the movie which I don't think was in a book that was not realistic at all was when he cuts his glove and does the Iron man thing. Oh, he's like, flying back to the spaceship. You can't really control it, that you would spin out of control. You'd also need a big hole to really get enough propulsion, and then your suit would deflate. I mean, it's just. That's just not going to work.
