Barking and busting balls like a young Joe Pesci, Jonah Hill is one of the best things in Martin Scorsese's insane The Wolf of Wall Street. As the right hand man to Leonardo DiCaprio's Jordan Belfort, Hill's character Donnie Azoff is pasteled down to the socks. His teeth are cocaine-white, matching all the shit he puts in his system.

Complex TV caught up with Jonah Hill to talk about what the performance required and where he drew inspiration from. Turns out the answer has far more to do with drug advisers than parties at James Franco's house. Check out the video above for insight into the making of one of the year's best movies.
