Bob Bell (March 21st, 1918 - June 6th, 2009) was the art director and supervising art director on Thunderbirds season 1 and 2 respectively. The same goes for the two feature films Thunderbirds Are Go and Thunderbird 6. Other work includes Supercar, Fireball XL5, Captain Scarlet and the Mysterons, UFO, and The Protectors.
He gave invaluable help with research for 21st Century Visions and was interviewed for Mr. Thunderbird: The Gerry Anderson Story. Additionally Bell - with the help of assistants Bill James, Mark Harris, and Mark Woollard - reconstructed the interior of Thunderbird 1 for the Thunderbirds Kit Kat advert.
