Castles In The Sky' tells the previously untold remarkable story of the fight to invent RADAR by Scotsman Robert Watson Watt and a team of British scientists. It conveys the genuine human drama behind the invention which saved the nation in the 'Battle of Britain.'Eddie Izzard joined the project because he was so inspired by the character and story: I feel very privileged to be playing the role of Robert Watson-Watt. Hopefully our production will allow him, along with Arnold 'Skip' Wilkins and their team, to finally take their places in the pantheon of British greats of World War II, as the inventors of RADAR.
