Thirty Seconds Over Tokyo is a 1944 American war film produced by Metro-Goldwyn-Mayer. The screenplay by Dalton Trumbo is based on the 1943 book of the same name by Captain Ted W. Lawson. Lawson was a pilot on the historic Doolittle Raid, America's first retaliatory air strike against Japan, four months after the December 7, 1941, Japanese attack on Pearl Harbor. The raid was planned, led by, and named after United States Army Air Forces Lieutenant Colonel James Doolittle, who was promoted two ranks, to Brigadier General, the day after the raid.

James Dalton Trumbo was an American screenwriter who scripted many award-winning films, including Roman Holiday (1953), Exodus, Spartacus, and Thirty Seconds Over Tokyo (1944). One of the Hollywood Ten, he refused to testify before the House Un-American Activities Committee (HUAC) in 1947 during the committee's investigation of alleged Communist influences in the motion picture industry.
