Video: Meet Tom Woodruff. You've seen him in movies but probably didn't even realise he was in them because he specialises in playing creatures. That is, he's been the alien in Aliens, a gorilla in various TV shows and movies, done work for Jumanji, and so much more. What's cool is to hear him talk about his craft and process and to see him act it out in an actual suit versus doing motion capture (not that there's anything wrong with that).
It's just really, really neat to see how movie monsters work.
