Produced by Britain's Teddington Studios on behalf of Warner Bros., The Flying Fortress stars Richard Greene, who had to be furloughed from the Army to participate in this wartime morale-booster. Greene plays millionaire playboy Jim Spence, a carefree aviation enthusiast whose avocation becomes his vocation when the war breaks out. Giving up wine, women and song for the duration (well, at least wine and song), Spence mans the controls of a British "flying fortress" for periodic bombing forays over Berlin. The film's "money scene" finds Spence clambering out of his plane to repair a hole in its side in mid-air-a bit of bravado which, amazingly, is based on a true incident. For unknown reasons, Flying Fortress was heavily edited for its American release, rendering its storyline a tad hard to follow at times. ~ Hal Erickson, All Movie Guide
