Film cans containing unseen footage of the Thunderbirds TV show have been found in a garden shed.

A family found the cans - light-tight containers used to enclose film - in a Buckinghamshire shed belonging to their father, who was an editor on the show and 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.
