He's the funny guy from Superbad and Get Him to the Greek, but it looks like actor Jonah Hill is taking his weight-loss plan very seriously.
He showed off his new slim-line physique at the ESPY Awards in Los Angeles last night after losing an astonishing amount of weight for his new role in 21 Jump Street, a reboot of the classic TV series originally starring Johnny Depp.
Jonah signed on for the film in early 2010, but in order to convincingly play his undisclosed character he was forced to lose weight.
The 27-year-old actor highlighted his new slim frame by wearing a smart black suit to the event, teamed with a striped purple shirt and matching tie.

The Superbad star has achieved his weight loss by seeing a nutritionist and working out with a trainer. In a recent interview with the L.A Times he admitted that the process had been a difficult one.

"It’s not fun. I wouldn’t say it’s the most fun endeavour I’ve ever took on in my life - but it’s important. And I’m enjoying it."
"If I eat something unhealthy now, I kind of feel a little weird and my body hurts."

As we remember him - Jonah with Get Him to the Greek co-star Russell Brand only last year.
