A thin, weasel-like Russian stage actor, David Hoffman made his mark in Hollywood films of the 1940s, chiefly at Universal where, as the spirit, he opened the first five Inner Sanctum films: Calling Dr. Death (1943), Weird Woman (1944), Dead Man's Eyes (1944), The Frozen Ghost (1945), and Strange Confession (1945). Hoffman was also an effective Hawaiian-based Nazi spy in a couple of chapters of the 1943 serial The Adventures of Smilin' Jack (1943) and portrayed yet another furtive Axis agent in the Marx Brothers comedy A Night in Casablanca (1946). Often unbilled, Hoffman continued in films until the late '50s. He should not be confused with the later director of the same name. ~ Hans J. Wollstein, All Movie Guide
