The cast of The Wolf of Wall Street is shaping up to be pretty epic. That's the kind of drawing power you get when you're Martin Scorsese, I suppose.

Today, shirtless lawyer Matthew McConaughey hops on board. He'll join Leonardo DiCaprio, Jonah Hill, Jean Dujardin, Jon Favreau, and Rob Reiner in the cast.

The Wolf of Wall Street is an adaptation of the book by Jordan Belfort, which tells the story of his days as a corrupt Wall Street trader, which resulted in a criminal conviction. DiCaprio will play Belfort, with McConaughey playing Mark Hanna, one of Belfort's early bosses.

Fans can see Leonardo DiCaprio in The Great Gatsby and Django Unchained this winter. McConaughey's new film, The Paperboy, will come out in October. Check out The Paperboy trailer for a look.

The Wolf of Wall Street is expected to begin production this Fall.
