Captain Kronos: Vampire Hunter (1974, Brian Clemens)

Contrary to his entry in IMDB, the World's Phoniest Bat does not appear in this film. Rather, the part of "Bat" is played by his cousin, the World's Most Immobile Bat. Born with rigiditis, a disease that only afflicts sentient bat puppets, TWMIB admired his cousin's success in the film industry, and yearned to live what he thought was his cousin's glamorous Hollywood lifestyle. Although TWMIB found a few paying jobs -- Captain Kronos was his most high-profile appearance -- there simply wasn't demand for a bat that had to be held in place by the "victim" to simulate a vicious attack, and TWMIB soon retired from the industry. He currently runs a BP station in Medford, Oregon. Ironically, he is unable to pump your gas.
