High Quality Content by WIKIPEDIA articles! Thunderbird 6 is a 1968 British science-fiction and adventure film written by Gerry and Sylvia Anderson, directed by David Lane and produced by Century 21 Cinema. A sequel to 1966's Thunderbirds Are Go, it is the second film to be adapted from the 1960s television series Thunderbirds, which combined scale models and special effects with marionette puppet characters in a filming process that the Andersons termed "Supermarionation." Intended to provide a lighter-hearted cinematic experience to contrast with the harder science of Thunderbirds Are Go, the Andersons elected to base the plot of Thunderbird 6 on Skyship One, a futuristic airship that is the latest project of the scientist Brains.
