8. Scarlett Johanssons Ripped Stunt Double (The Avengers)
Good stunt actors are essential to any action film, knitting movies together with their honourable disregard for safety in the name of cinema. In fact, Scarlett Johanssons noticeably more muscular stunt double can clearly be seen when Black Widow does a flip whilst tied to a chair, so you can appreciate her work for yourself next time you sit down to watch The Avengers. The ironically named Heidi Moneymaker will have received a fraction of Johansson's fee despite portraying Black Widow in some of her most memorable scenes in the movie.
