Amitabh Bachchan is an intelligent actor.
Actors are not necessarily smart people.
There's nothing more boring than unintelligent actors, because all they have to talk about is themselves and acting. There have to be other things.
I've been described as a smart actor because I've attended college. Or I've been called an artsy jock. And I am thinking, 'So, are actors supposed to be dumb?'
Generally speaking, actors are allowed NO input. Actors are dumb.
The better the actor, the more stupid he is.
Read more. Read. Read. Read. Deeply, widely, read. Learn all kinds of subjects. The smarter you are as an actor, the better an actor you'll be.
I know plenty of actors smarter than me with better taste than me who love horror movies and love sci-fi and it just doesn't make sense to me.
If you're ever making a television show, don't cast smart actors because they are just a pain in the ass. The moment you start to bullshit them you've lost them, so you have to either know what you're talking about or when you don't talk to them.
I do believe all actors are smart.
