Yeah, but he is wrong. Nothing compares to a good method actor. Look at some of the most brilliant and memorable roles in movies and they were not done with merely "a strong voice and superb diction." Say Al Pacino in scarface or Marlon Brando in the godfather, these people became the character (and both had really bad diction, btw).
I think his instructions are for average actors, who think they are Marlon Brando and do a bad Brando impersonation when acting. These are the actors that drive directors crazy, so directors always tell them to keep it simple.
