 Harwood stated in an interview in a "Cinema Retro" special on the making of the film that she had been a screenwriter of several of Harry Saltzman's projects; she claimed both her screenplays for "Dr. No" and her screenplay for "From Russia with Love" had followed Fleming's novels closely.During the series' decades-long history only a few of the films have remained substantially true to their source material; "Dr. No" has many similarities to the novel and follows its basic plot, but there are a few notable omissions.Major elements from the novel that are missing from the film include Bond's fight with a giant squid, and the escape from Dr. No's complex using the dragon-disguised swamp buggy.
