Buster Keaton of feature films. Throughout the 1940s, Keaton played character roles in both "A" and "B" features. He made his last starring feature "El Moderno Barba Azul" (1946) in Mexico; the film was a low budget production, and it may not have been seen in the United States until its release on VHS in the 1980s, under the title "Boom in the Moon".
