Leonardo DiCaprio and Matthew McConaughey got an early start at work on the set of The Wolf of Wall Street this morning in NYC. Both guys were seen arriving in casual clothes and carrying coffee mugs before suiting up to get into character. Leo was spotted filming last week as production on the Martin Scorsese-directed project began. He and Matthew are being joined by Oscar-winner Jean Dujardin of The Artist and Jonah Hill in the film, which is set in the world of high-stakes finance in 1990s Manhattan. Both Matthew and Leo underwent a bit of a physical transformation before getting to work on the movie, with Matthew looking noticeably slimmer and Leo shaving his beard to play a stockbroker.
