6. James Cameron Used His Own Hands For The Scene Where Jack Sketches Rose - Titanic
Titanic is known for being "that film that made all that money," and also because it gave us a scene where Kate Winslet exposed herself (although you could probably randomly pick any movie from her filmography to see her doing that). In one of the movie's most famous scenes, third-class scumbag Jack (Leonardo DiCaprio) shares an intimate moment with first-class beauty Rose (Winslet), who asks him to sketch her wearing nothing but a glamourous neckless. Whilst watching these scene, one could be forgiven for thinking that DiCaprio was allowed to play his own character's hands, but no - director James Cameron had a different idea. "Wouldn't it be better if I were actually Jack's hands in this scene?" he presumably said. "Not because of the nudity or anything, but because of the..." But he trailed off, having already taken his position on set. And that was the story of James Cameron's hands in Titanic. Probably.
