Mac told David Letterman on CBS' "Late Show" that he'll retire after he finishes shooting the comedy film "The Whole Truth, Nothing but the Truth, So Help Me Mac" this fall.
"And I'm going to put it in theaters and it's going to be 30 years for me, and I'm going to call it," the 49-year-old comedian said on Monday night's show.
"I'm going to still do my producing, my films, but I want to enjoy my life a little bit," Mac told Letterman. "I missed a lot of things, you know. I was a street performer for two years. I went into clubs in 1977."
"It's a great way to make a living but it also, it takes a toll, doesn't it? It's tough," Letterman said.
"Oh, man, you miss out on so much, you know, and you live in all these hotels - I was on the road 47 weeks out of the year," said Mac, who starred with D.L Hughley and Cedric the Entertainer in 2000's "The Original Kings of Comedy."
Said Letterman: "So, one last film record of your work."
Mac replied: "That's right. ... Comedy has been so good to me. And that's all I ever wanted, watching you guys. I had great mentors - Jackie Gleason, Flip (Wilson), Redd Foxx, Richard Pryor, Bill Cosby, Buddy Hackett. I had so many people to watch, that today you don't have that anymore."
His new film, "Pride," will be in theaters Friday.
RANCHO PALOS VERDES, Calif. - Keanu Reeves was behind the wheel of a Porsche that allegedly grazed a celebrity photographer standing in the path of the sports car, investigators said Tuesday.
The photographer fell to the ground and paramedics were called after Reeves' car allegedly struck the man at 7:30 p.m. Monday, said Deputy Ed Hernandez of the Los Angeles County Sheriff's Department.
Reeves, 42, wasn't hurt.
The Associated Press left a phone message for a representative of the actor seeking comment.
"He grazed a paparazzi standing in front of his Porsche and the man fell to the ground," Hernandez said. It wasn't known how fast the Porsche was traveling.
Reeves was leaving a parking space in the Avenida Tranquila residential area near Los Verdes County Golf Course about 30 miles south of downtown Los Angeles, he said.
The photographer, whose name wasn't released, was taken to a local hospital for treatment of unknown injuries, Hernandez said.
The Sheriff's Department was investigating.
