A feature-length pilot about the NASA pilot accidentally frozen for over 500 years and waking up in the far future, was released theatrically in March 1979 (capitalising on the success of Star Wars two years earlier), and spawned a television show which lasted for two seasons from 1979 to 1981.

These authentic items used in the production of the television series were photographed on display at Universal Studios Hollywood on January 7, 2011.

'Twiki' was 'Buck Rogers' robotic sidekick and often wore the computer intelligence 'Dr. Theopolis' around his neck.

Felix Silla was the actor behind the mask in the robot suit, but Mel Blanc provided his voice for the majority of the series, aside from in the second season when he was voiced briefly in a few episodes by Bob Elyea.

Twiki's catchphrase was 'bidi-bidi-bidi'.
