Director Cameo: [Alfred Hitchcock] about five minutes into the movie in the town square wearing a coat and a brown hat. Ten minutes later he is one of three men on the steps of government house.
Many French critics consider Under Capricorn as one of Hitchcock's finest films.
In 1958, Cahiers du Cinema (French Film Magazine) voted Under Capricorn (1949) as one of the ten greatest films of all time.
In his autobiography "Vanity Will Get You Somewhere", actor Joseph Cotten referred to this film as "Under Corny Crap".
Burt Lancaster was the original choice to play Sam Flusky in Under Capricorn (1949), but the part went to Joseph Cotteninstead because Lancaster was deemed too expensive.
Margaret Leighton appeared with her future husband Michael Wilding in this film. After their marriage in 1964, they worked together several more times, but, by his own admission, Wilding preferred retirement and was happy just to be a supportive audience member for his wife. In this film, Michael Wilding played Charles Adare and Margaret Leighton played Milly.
According to Michael Wilding's autobiography "The Wilding Way", on one occasion while Ingrid Bergman and Michael Wilding were in the middle of a passionate love scene Hitchcock let out a howl of pain, then in the most gentle tone said "Please move the camera a little to the right. You have just run over my foot." The X-ray revealed later that the camera's weight had broken Hitchcock's big toe.
