A double bill of Gerry Anderson's cult Supermarionation movies. 'Thunderbirds Are Go' was the first of the 'Thunderbirds' movies and sees International Rescue helping out with security on a beleaguered mission to Mars. Thanks to their efforts the landing goes off without a hitch, but on the return journey the high-tech spaceship is badly damaged and threatens to crash land in a densely populated area. That means it's time for the Tracy brothers to do what they do best. Scramble the rescue vehicles! Thunderbirds are GO! 'Thunderbirds Six' was the second of the 'Thunderbirds' films. This time round, Tracy Island's resident genius Brains designs a revolutionary new aircraft, the Skyship One, only to see it hijacked on its maiden voyage. The Thunderbirds team get ready to come to the rescue, but with Alan Tracy and Lady Penelope trapped on board the Skyship, and Thunderbirds 1 and 2 heading into a trap set up by the hijackers, it's not going to be that easy.
