Gerry Anderson's son has discovered a treasure trove of previously unseen Tv scripts written by the Thunderbirds creator before his death.

The Tv mogul, who was famed for his puppet-based adventure shows, passed away in December (12), and his son Jamie has now found numerous writing projects on his dad's computer.

Jamie discovered his father was working on a book and a children's Tv show, and he has also unearthed completed scripts and notes dating back to the 1970s.

He tells The Sun, "We found endless ideas - jottings, project synopses, even full scripts. There's stuff going back to 1978 that's never been seen before."

Most of the work was found on Anderson's computer, which was stored in a garden shed at his home in Oxfordshire, England.
