Produced, directed and scripted by Peter Ustinov (who did not star), Secret Flight was released in Great Britain in 1946, but not distributed in the U.S. until 1951 -- at which time it was panned as being out-of-date! The fact-based screenplay details the efforts of five dedicated British scientists to develop Radar and other preventative measures on the eve of WW II. The five "boffins" are played by Ralph Richardson, Raymond Huntley, John Laurie, Ernest Jay and David Tomlinson. Some excitement is engendered when a test pilot (Richard Attenborough) cooperates with the scientists' remote-control airflight experiments. Given the film's sober treatment of certain British wartime military maneuvers, it is surprising that Peter Ustinov frequently chooses to depict the scientists as Dr. Watson-style comic figures.
