Joaquin Phoenix
The 'Napoleon' star never took acting lessons but got into the industry when his mother met child agent Iris Burton.
Phoenix has previously bemoaned how most acting lessons are "completely wrong".
The Oscar-winner told Interview magazine: "They tell you to memorise your lines, follow your light, and hit your marks. Those are the three things that you shouldn't do.
"You should not learn your lines, you should not hit your mark, and you should never follow your light.
"Find your light - that's my opinion. Everyone else will tell me I'm wrong, but that's my opinion."
