- Produced by Audrey Hepburn's then-husband, actor Mel Ferrer. Hepburn's film residence is at 4 St. Luke's Place in Manhattan.
- Audrey Hepburn and director Terence Young attended a school for the blind to learn more about the visually impaired. Hepburn even learned to read Braille.
- Hepburn had to be fitted with special (and painful) contact lenses because her eyes were deemed too expressive for a blind person.
- Despite getting an Oscar nomination for this movie, Hepburn would not make another film until Robin and Marian (1976).
- When the film was released, the theatres darkened all their lights "to the legal limit" during the last twelve minutes of the film, each light going out as Audrey Hepburn smashed each light bulb. The one remaining light in the theatres would be switched off as the last light source in the film went out.
- The role that eventually went to Alan Arkin was difficult to cast because the producers couldn't find actors willing to be cast in such a villainous role -- not only terrorizing a blind woman, but terrorizing beloved Audrey Hepburn to boot! Hepburn tried to get this film shot in Europe, but relented when she was told not filming it in the US might have led to the closure of underused studio facilities in Hollywood.
