Matthew McConaughey drops weight for his new movie role

Matthew McConaughey is almost as famous for his rippling muscles as he is for his acting, so we were shocked when we saw this picture (left) of the star looking gaunt on the set of his new movie.

Matthew was snapped in New York filming The Wolf Of Wall Street and, compared to how he looked in Magic Mike (right), he has clearly dropped lots of weight.

But he isn't the only actor to change his appearance for a role - flick through our gallery to see which other stars have transformed for the big screen.
