Behind the scenes of the production of three new episodes of the classic television show Thunderbirds - exactly the way it was done in the 60s! The team behind the Thunderbirds 50th Anniversary episodes have now produced their own show. To celebrate the 50th anniversary of Gerry and Sylvia Anderson's classic Thunderbirds, the team from Century 21 Films produced three brand new episodes of the series using all the classic techniques. The special episodes – Introducing Thunderbirds, The Abominable Snowman, The Stately Homes Robberies – were based upon three original 1960s voice recordings and produced in association with copyright holders ITV. Their task was to build sets, puppets, and models matching the originals and to marry them with those adapted voice recordings. The final effect should make the audience feel that they're watching three long-lost episodes. The series premiered at the BFI in August 2016, and has enjoyed subsequent screenings at Vue Cinemas and now on Britbox UK.
