The Lost Planet

The Lost Planet is a 1953 Columbia Pictures 15chapter serial which has the distinction of being the last interplanetarythemed sound serial ever made. It was directed by Spencer Gordon Bennet with a screenplay by George H. Plympton and Arthur Hoerl who also wrote for Rocky Jones, Space Ranger. It appears to have been planned as a sequel to the earlier chapterplay Captain Video Master of the Stratosphere and shares many plotpoints, props and sets, as well as some of the same cast. However, the Video Rangers do not appear, and their uniforms are instead worn by slaves created electronically by Reckov, the dictator of the Lost Planet Gene Roth with the help of mad scientist Dr. Grood Michael Fox and enslaved good scientist Professor Dorn Forrest Taylor.

Unlike the Captain Video serial, The Lost Planet has a female character, Professor Dorns daughter Ella Vivian Mason who strides about the Lost Planet Bronson Canyon in a fetching female version of the Video Ranger uniform. The hero is not Captain Video, but a newspaper reporter, Rex Barrow, played by Judd Holdren who had previously played Captain Video and Commando Cody. Books on the sound serials generally conclude that this is one of the worst serials ever made, but it still has points of interest. The bizarre performance of Michael Fox 19211996 as the villainous Dr. Grood is particularly memorable. This is one of Foxs first screen roles. He went on to a long and distinguished career as a character actor in dozens of feature films and hundreds of TV series right up to his final illness and death.This serial was, despite the characters names, essentially a sequel to Captain Video, from which stock footage was taken for this serial. ........
