Burt Lancaster Biography

Burton Stephen "Burt" Lancaster (November 2, 1913 – October 20, 1994) was an American film actor and star, noted for his athletic physique, distinct smile (which he called "The Grin") and, later, his willingness to play roles that went against his initial "tough guy" image. Initially dismissed as "Mr Muscles and Teeth", in the late 1950s Lancaster abandoned his "all-American" image and gradually came to be regarded as one of the best actors of his generation.
