As declared by the 'Hollywood Reporter' of 4-6 August 2000, the screen-writing credit of Raymond T. Marcus for this film is actually an alias for blacklisted scriptwriter Bernard Gordon
. Gordon once said that he thought that it was ironic that he could not put his name to the script due to a blacklist that the actual movie's star Ronald Reagan
denied ever existed (to Joseph Alsop in 1980). See more
