This is a Caricature of Matthew McConaughey from the 2014 Academy Award nominated film, Dallas Buyer's Club. Matthew won best actor for his performance as well. It was a powerful movie and he did a wonderful job. He was almost unrecognizable with all that weight that he lost to fit the role in the movie. So much that a lot of people don't recognize this painting as him. But if you saw the movie, you'd know right away who it is and what scene this is from.
