The 1929 film "The King of the Kongo" featuring Boris Karloff was the first movie sound serial, not seen for more than 80 years. The surviving prints of the film do not include sound, because the sound was originally played from Vitaphone discs that have long been lost.

Film collector and preservationist Eric Grayson discovered three of those discs and has restored one chapter of the serial including original sound. The surviving film was dark and substantially worn, but Grayson painstakingly cleaned up and enhanced the picture quality along with music, effects, and dialogue.

Screening of the restored 16 mm film will be preceded by a discussion and demonstration of the restoration process by Grayson
