Jon Hamm wants to be the next George Clooney.

The 'Mad Men' actor - who has long-been compared to the Hollywood hunk - confesses he would "love to emulate" the 'Men Who Stare At Goats' star's career because of the variation of his work.

He said: "We already have a perfectly serviceable George Clooney, but that's certainly someone whose career I would love to emulate because he's been able to work in various genres and walk the line between drama and comedy.

"He also got started very late in life because 'ER' came when he was well into his thirties, so he bounced around, not unlike me, from show to show and failed pilot to failed pilot, and then 'ER' happened and he blew up."

However, despite wanting a career like Clooney, 'The Town' star admits acting was not always his first love and he spent his childhood dreaming of working under the sea with fish and in space.

He told Total Film: "I wanted to be a marine biologist, a teacher, and astronaut and an actor, and my parents never said, 'You can't do that,' or, 'That's not realistic.' So when I decided to move to New York and try out acting on a whim, they didn't stop me.

"It turned out to be something I loved and I've been lucky enough to be able to do this for a job, so far."
