Jack Nicholson reportedly retired from acting?

If true, news so sad it’s tough to even contemplate. From RadarOnline.

He’ll still sit court side at Los Angeles Lakers’ games, but Hollywood legend Jack Nicholson has quietly retired from the movie business, RadarOnline.com has exclusively learned.

The 76-year-old icon has no plans to appear in films again after a career spanning five decades.

“Jack has — without fanfare — retired,” a well-placed Hollywood film insider confirmed to Radar.

“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.”

The three-time Academy Award winner has not worked since How Do You Know in 2010 starring Reese Witherspoon, Paul Rudd and Owen Wilson.

Tellingly, producers for the forthcoming film Nebraska had wanted him to play the key role of an aging, booze-addled father who makes the trip from Montana to Nebraska with his estranged son in order to claim a million dollar Mega Sweepstakes Marketing prize…

“Jack has no intention of retiring from the limelight,” said the source, who noted his regular appearances on the Hollywood party circuit, court side at his beloved Lakers and his co-presentation of the Academy Award for Best Picture with First Lady Michelle Obama, earlier this year.

“He’s not retiring from public life, at all. He just doesn’t want a tribute,” added the insider. “He’s happy to tacitly join the retirees club like Sean Connery.”
