Ashton Kutcher has admitted he sometimes wishes he had a rewind button, so he could reset his career and stay under the radar.
The Hollywood star - who is married to actress Mila Kunis - said he would quite like it if people didn't know much about him, and thinks it would make his characters more believable.
He told the Associated Press: "Sometimes as an actor I wish I could start my career over where people don't know anything about me and I'd never do an interview and I'd never do a talk show because I'd never want them to know anything about me."
Ashton, 38, went on: "Most people probably wouldn't recognise Gary Oldman in his everyday life because they have no idea how he walks and how he talks. He's such a chameleon from role to role.
"I think if you can do this job and be successful at the level of success you want to attain and do it without any of the fame -- that would be the ultimate gig."
Ashton and Mila have a daughter, Wyatt, and Mila is expecting their second child later this year.
