Thunderbirds Are Go: Puppet Adventurers Of The Groovy '60s

Thunderbirds Are Go

For fans of cult '60s TV, the Thunderbirds and catchphrase "Thunderbirds are go!" bring back fond memories of sci-fi puppetry and marionette action that was far better than it should have been. Marionettes on TV -- Howdy Doody, for instance -- were not known for their sophistication. But Thunderbirds and the shows that preceded it (Thunderball XL5, Stingray and others) used its brand of "supermarionation" to deliver real drama and action over silliness played for yuks.

Thunderbirds depicts the adventures of the the Tracy family, led by Jeff Tracy, a former astronaut who works with his adult sons to form International Rescue, an organization created to save life on Earth. The squad is an unstoppable, futuristic rescue team made entirely of puppets. Thunderbirds was yet another manifestation of the 1960s spy and secret-agent craze that permeated entertainment, from The Avengers to James Bond to Get Smart to The Man From U.N.C.L.E. And in fact, Thunderbirds, produced in the United Kingdom, was breaking ground as serious action puppetry at the same time the American production Jonny Quest was pioneering serious action cartoons.

What's 'Supermarionation'?

In the early 1960s Gerry and Sylvia Anderson met while working at AP Films. He was producing a series called The Adventures of Twizzle, and she was working as his secretary. While working on the western fantasy-adventure series Four Feather Falls, Anderson hit on something spectacular a TV-ready version of puppetry he would call "supermarionation." This groundbreaking production technique combined pre-recorded audio with marionettes who were filmed as if they were live-action movie stars.

Each marionette's head held filters that converted dialogue into pulses that enabled the puppet's mouth to move in time with the recorded speech. Inspired by Ray Harryhausen's stop-motion "Dynamation," Anderson combined the words “super,” “marionette” and “animation,” to form Supermarionation. Even with a cool name and technology that made filming easier, Anderson still had some trouble with his technique. For instance, the marionettes couldn't walk convincingly. Pretty much any sequence in Thunderbirds that calls on characters to walk, fall, or jump looks hilarious, so Anderson made sure to put his characters in vehicles as much as possible.
