When you use the same actors a lot, you get to know them and you realize that one movie can't explore all the talent that they have. You really have to give them several different kinds of roles, in completely different movies, to push them and to push yourself.
Don't give me any money, don't give me any people, but give freedom, and I'll give you a movie that looks gigantic.
Sometimes a movie series that becomes popular can be a blessing and curse because you get known for that. People don't give you a chance, after that... I'm a big proponent of getting somebody that you always admire and giving them a chance to do something else because they can redefine themselves.
