Fearless Fagan is a 1952 American comedy film directed by Stanley Donen and stars Janet Leigh and Carleton Carpenter. It is about a clown who is drafted into the military and tries to sneak his pet lion into the service. The film was inspired by the 12 Feb 1951 Life Magazine story Fearless Fagan Finds a Home where Private Floyd D. Humeston requested an emergency 14-day furlough from Ft. Ord, California to take care of his pet lion. Fagan played himself with the army assigning Pvt Humeston to act as a technical adviser on the film.
