John Joseph "Jack" Nicholson (born April 22, 1937) is an American actor, film director and producer. He is renowned for his often dark-themed portrayals of neurotic characters.
Nicholson has been nominated for Academy Awards twelve times. He won the Academy Award for Best Actor twice, for One Flew Over the Cuckoo's Nest and for As Good as It Gets. He won the Academy Award for Best Supporting Actor for the 1983 film Terms of Endearment. He is tied with Walter Brennan for most acting wins by a male actor (three), and second to Katharine Hepburn for most acting wins overall (four). He is also one of only two actors nominated for an Academy Award for acting (either lead or supporting) in every decade from the 1960s to 2000s (the other one being Michael Caine). He has won seven Golden Globe Awards, and received a Kennedy Center Honor in 2001. In 1994, he became one of the youngest actors to be awarded the American Film Institute's Life Achievement Award.
Notable films in which he has starred include, in chronological order, Easy Rider, Five Easy Pieces, Chinatown, One Flew Over the Cuckoo's Nest, The Shining, Reds, Terms of Endearment, Batman, A Few Good Men, As Good as It Gets, About Schmidt, Something's Gotta Give, and The Departed. 
In an 1992 interview in Vanity Fair, Jack Nicholson said, "I don't believe in God now," but he added that "I can still work up an envy for someone who has a faith. I can see how that could be a deeply soothing experience."
"I resist all established beliefs. My religion basically is to be immediate, to live in the now. It's an old cliche, I know, but it's mine. I envy people of faith. I'm incapable of believing in anything supernatural. So far, at least. Not that I wouldn't like to. I mean, I want to believe. I do pray. I pray to something ... up there. I have a God sense. It's not religious so much as superstitious. It's part of being human, I guess ... Do unto others: How much deeper into religion do we really need to go?" - Jack Nicholson, Esquire, January 2004
