As we learn that 3-time Oscar-winning actor Jack Nicholson is quietly retiring from acting at 76 he is reportedly suffering from memory loss, it was easy to think of some great moments in film that were all about him.

Sources told Radar that Nicholson has "memory issues" and while many might jump to the conclusion that the actor is in the beginning stages of Alzheimer's, there is no indication he is suffering from any particular disease. Nicholson hasn't appeared in a film since a supporting role in 2010's 'How Do You Know' with Paul Rudd and Reese Witherspoon.

Nicholson is the most-nominated actor in Oscar history with a total of 12 nominations (8 for Best Actor and 4 for Best Supporting Actor) and has received an Oscar nomination every decade from the 60s through the 2000s. He won in 1976, 1984 and 1996 for 'One Flew Over the Cuckoo's Nest,' 'Terms of Endearment' and 'As Good As It Gets' respectively.

Here are my favorite performances from Jack.

Batman (1989)

Sure, it's campy now, but back then we had never seen Batman on the big screen in this way. Heath Ledger really took the character of Joker Jack Napier to a darker level, but Jack's performance and 'Joker laugh' was still epic!

The Shining (1980)

I am not lying when I tell you that the trailer for this movie had me so horrified as a kid that I couldn't go outside at night alone during most of the year 1980 and 1981. The man with the axe was Jack.

Thanks.

The Witches of Eastwick (1987)

Maybe it was John Updike's writing. Maybe it was Jack, who I I never thought of as sexy. He's just not my type. I think I'm in the minority there, though.

The Radar source says that Nicholson will still attend Lakers games and the Oscars but will otherwise make like his friends Gene Hackman and Sean Connery and quietly fade away from a career on the big screen.
