I was in the National Academy of Fine Arts and Design, on a scholarship. I was - still am - an artist. They were looking for an actor for 'Take a Giant Step,' and a producer liked my look and asked if I could act. I said, 'Yep!' Then I got into acting more or less just to make money for paints and canvases.
