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.
