"I'm very proud of my performance in One Flew Over the Cuckoo's Nest, but my teenage self would be most impressed that I played the Penguin in a Batman movie" DeVito told The Big Issue in his 'Letter to My Younger Self'.
"He has the comic book on his bed. I'd have to tell him that it would turn out a bit different from the comic though, because of this crazy thing called Tim Burton."
He added: "If I told him he was going to direct and perform in all these movies and have three kids and live the life I've lived, I think he'd close his eyes and smile and say, 'Fantastic'."
