The Man Who Found Himself, also known as Wings of Mercy, is a 1937 American aviation film based on the unpublished story "Wings of Mercy" by Alice B. Curtis. The film marked the first starring role for 19-year-old Joan Fontaine, who was billed as the "new RKO screen personality", highlighted following the end of the film by a special "on screen" introduction. Unlike many of the period films that appeared to glorify aviation, it is a complex film, examining the motivations of both doctors and pilots.
