Jonah Hill had the world at his feet as a comedy actor, but made the brave step of drastically changing his appearance when he decided he wanted to take on more serious roles. He had us all rolling in the aisles in 'Superbad' and 'Knocked Up,' and turned in a truly memorable performance as Leonardo DiCaprio's sidekick in 'The Wolf of Wall Street.' Hill was so keen to land that role that he worked for less than a tenth of his usual rate just so he could take the part. That shows you how serious he is about his craft - as does his dramatic weight loss.
If you go back five or six years, Hill was roughly twice the weight he is now. He looks happier and healthier - but shrinking down so much has drawn attention to the fact that he's a lot shorter than people who saw 'Superbad' must have thought. Hill is 5 foot 7. He may have lost a lot of size, but he hasn't lost any of his on-screen presence! He credits acting buddy Channing Tatum with helping him to get into shape.
