Steve McQueen as Thomas Crown. - He was excellent at acting with his mouth shut. He had very few lines in some of his best movie performances, and the lines he did have were very short (for example "The Thomas Crown Affair", and "Bullitt").
During the filming of "The Great Escape" Steve McQueen, James Garner & Bud Elkins blew off some steam racing go-karts. This pic may be back then, but this go-kart is different from the one most photographed in those races.
