The film's producers were forced to shoot a new version of the opening credits of Superman - Retter in der Not (1952) when Warner Brothers refused permission for the actual opening credits to be used within the film.
The film was originally entitled Truth, Justice, and the American Way, however, DC Comics refused to allow it. They also would not allow the Superman "S" insignia to be used in any of the trailers or promotional material of the film, but oddly enough allowed it to be in the movie.
The title refers to the famous Hollywood sign which originally read Hollywoodland, promoting a real estate project in the 1920s. The last four letters were removed in 1949.
The Alvis automobile George Reeves is shown washing in the film is an extremely rare model that was shipped to the location for use in the movie, as it is one of the few existing examples of the car Reeves actually owned.
George Reeves's biographer, Jim Beaver, served as a historical consultant on this film and was offered a role. He was unable to accept, due to conflicts with his Deadwood (2004) schedule. Coincidentally, two of his Deadwood (2004) co-stars, Molly Parker and Larry Cedar, appear in the film.
