Thirty Seconds Over Tokyo is a 1944 American war film released by Metro-Goldwyn-Mayer. It is based on the true story of the Doolittle Raid, America's first retaliatory air strike against Japan four months after the December 1941 Japanese attack on Pearl Harbor.
Mervyn LeRoy directed Thirty Seconds Over Tokyo and Sam Zimbalist produced the film. The screenplay by Dalton Trumbo was based on the 1943 book of the same name, by Captain Ted W. Lawson, a pilot on the raid. The film stars Van Johnson as Lawson, Phyllis Thaxter as his wife Ellen, Robert Walker as Corporal David Thatcher, Robert Mitchum as Lieutenant Bob Gray and Spencer Tracy as Lieutenant Colonel Jimmy Doolittle, the man who planned and led the raid.
In the book Lawson gives eyewitness accounts of the training, the mission, and the aftermath as experienced by his crew and others who flew the mission on April 18, 1942. Lawson piloted "The Ruptured Duck", the seventh of 16 B-25s to take off from the aircraft carrier USS Hornet. The film is noted for its accurate depiction of the raid and use of actual wartime footage of the bombing aircraft.
