Jonah Hill is known for being the happily plump funny-man who wins his audiences over with his great humour.
But with his recent dramatic transformation, the actor is barely recognisable of late.
The 27-year-old has lost an impressive 30lbs to prepare for his new movie role in 21 Jump Street, a reboot of the classic TV series originally starring Johnny Depp.
The Get Him To The Greek actor signed on for the film in early 2010, but in order to convincingly play his undisclosed character he was forced to lose weight.
According to Us Weekly, Hill shed all his goal weight of 30 pounds, but like many dieters started off by gaining rather than losing.
