After nearly seven decades in Hollywood, Michael Caine has announced that his acting career has come to an end.

The 90-year-old English actor revealed the news in an interview with BBC Radio where he highlighted the moment he decided it was time to retire.

 "I keep saying I'm going to retire," Caine said. "Well, I am now."

His latest movie "The Great Escaper," where he stars as a man who escapes from his care home to attend the 70th Anniversary of the D-Day Landings, will be his last project. The Warner Bros film released in theaters on Oct 6.

"I've figured, I've had a picture where I've played the lead and it's got incredible reviews," Caine said. "The only parts I'm likely to get now are old men, 90-year-old men, maybe 85. And I thought, 'Well, I might as well leave with all this.'"

"The Dark Knight" actor urged the importance for older actors to continue to be featured onscreen during the interview. He said his last few roles were greater parts that the ones he remembers men at 90 taking when he was younger, calling the roles "tiny old men with humped shoulders."

And while he gave a farewell to show business, he said fans will hear from him further with a future book. He said creating his debut thriller, "Deadly Game," which comes out in November, was enjoyable enough for him to commit to a future of writing. Plus, writing a book requires a lot less effort, he added.

"The thing about movie making is you have to get up at 6:30 in the morning, do a long ride learning lines in the car and then get there working until 10 o'clock at night," Caine shared. "With writing you don't have to get out of bed."

Throughout his career, Caine collected six Oscar nominations, won two Academy Awards, three Golden Globes, a Screen Actors Guild Award and a BAFTA. He's also written two memoirs including 1992’s “What’s It All about” and 2010’s "The Elephant to Hollywood.” 

The actor previously caused confusion about a false retirement in 2021 when he told a BBC radio program that his film "Best Sellers" would be his last and told the Guardian that he was stepping away from acting.

He soon clarified that he wasn't done acting yet in a post on X (formerly Twitter) where he said, "I haven’t retired and not a lot of people know that."

"Regarding retirement, I’ve spent over 50 years getting up at 6 a.m. to make movies, and I’m not getting rid of my alarm clock!" he said in a statement to Variety in 2021.
