Unseen Thunderbirds films found in garden shed
A family found the cans - light-tight containers used to enclose film - in the shed belonging to their father, an editor on the show who died recently.
Stephen La Rivière from Century 21 Films, which received the 22 old cans, said they mainly contained Thunderbirds material from the 1960s, including an alternative version of an episode that was never broadcast.
It is hoped the footage - filmed on the Slough Trading Estate in Berkshire - can be shown to the public as part of the series' 60th anniversary next year.
He said they were difficult to identify because of the condition, but "clearly the majority of it was Thunderbirds".
The only way to get a proper look at the material was to transfer it to digital, and so began the "very, very slow" process of scanning it.
"Every night I'd get a link for a download of the latest one that had been scanned... you'd never know what you'd get."
