Entertainment Young actors who 'quit' acting March 11, 2014 3:33 PM Print Share fbShare Tweet Email Lena Dunham may not want to continue acting once "Girls" is over, she says in Glamour's latest issue. Yes, she's only 27 and relatively new to the spotlight, but Dunham isn't the only actor to publicly toy around with the idea of quitting on-screen work at a young age. History has shown us, however, that even the stars who claim to be over Hollywood for good end up coming back for more.

"I know 24 is a young age to retire but you heard it here first I've #retired." One month later she announced she'd "unretired," and started promoting her next movie, "Easy A."

He then showed up at a screening of his film, "Nymphomaniac Volume I," with a paper bag over his head that said "I am not famous anymore." He reportedly will not be attending the New York premiere of the film, though he appears to still be acting, with another film in pre-production, according to IMDb.

"I?m 36, but I?ve been doing this for 20 years." He must have changed his mind, because he is set to star in 2014 ABC series "Secrets & Lies."

"I don't find Hollywood interesting, so I'm thinking about studying architecture instead," he said. He has worked on about 10 films since making that statement, and is currently working on "Outcast" with Nicolas Cage, who has also said he is tired of acting.

"I've done that, but now it's important and liberating to be on the other side of the lens. I don't like to be the center of attention anymore," Ashley, then 25, said, adding that if she ever returns to Hollywood it won't be as an actress. Mary-Kate agreed, saying being out of the spotlight "just felt right." The two have since been focusing on their fashion lines.

In a 2011 interview with Australia's 60 Minutes, the star said he would remain on-screen for only three more years. "I am really enjoying the producing side and development of stories and putting those pieces together," he said. Share on Facebook Share on Twitter Comments We're revamping our Comments section.
