Renowned thespian Jack Nicholson has reportedly retired from acting.
The 76-year-old film legend is stepping away from movies after a career spanning five decades, which has seen him appear in many iconic films including The Shining, , Easy Rider and Chinatown.
A source told RadarOnline.com: "Jack has - without fanfare - retired. There is a simple reason behind his decision, it's memory loss. Quite frankly, at 76, Jack has memory issues and can no longer remember the lines being asked of him. His memory isn't what it used to be."
Jack's illustrious career has included three Oscar wins, two for Best Actor in One Flew Over the Cuckoo's Nest and As Good as It Gets and a Best Supporting Actor statuette for his turn in the 1983 film Terms of Endearment.
Jack has previously singled out his role as 'The Joker' in Tim Burton's 1989 version of Batman with Michael Keaton in the lead role as a personal favorite. He said: "I was particularly proud of my performance as The Joker. I considered it a piece of pop art."
Jack is also philosophical about his fame, saying he believes he has "done OK"
In an interview published in Britain's Esquire magazine, he said: "I take responsibility for my successes as well as my failures. But when I look at my professional mistakes, I'm always left with the feeling that maybe I should have done more. These are my private musings.
"I'm such a perfectionist. I always feel over-praised, or whatever. In the abstract, I know I'm a good person, a good professional. But it's nice to be noticed a little bit, ain't it?"
The last film Jack appeared in was 2010s How Do You Know, which also starred Reese Witherspoon, Paul Rudd and Owen Wilson.
