Claimed near the end of his life to have appeared more movies than any other actor, surpassing the record set by Donald Crisp, the Oscar-winning actor and director who had started in silent films and had appeared in numerous one and two-reel films, many of them lost. The title for actor who appeared in most films likely is a contest between Carradine (more than 300 films) and Crisp (at least 170 known films). Of the contemporary generation, Christopher Lee, who has acted in more films than his peers (over 200 films), does not come close to matching Carradine's profligacy.
