* FieryRedhead: Scully, of course, but also Scully's "double" in 1939.
* GoodIsNotNice: The ship crew are rather abusive towards Mulder and eager to torture and kill him. Even if he ''was'' a Nazi spy as they suspect, their behavior is extremely morally dubious considering he is unarmed.
* LadyInRed: The other "Scully".
* TheOner: Close to it. The episode appears to be four continuous shots, with commercial breaks between them. In reality, the Steadicam they were using could only hold four minutes' worth of film, so there are numerous disguised cuts within each "oner."
* ShoutOut: Many to ''Film/TheWizardOfOz'', of course; some of the more subtle ones include that the captain of the ship is named Yip Harburg (the film's songwriter) and the story takes place in 1939 (the year the film was released).
* TwoFistedTales: Had elements of this, especially the big ballroom punch-up between British sailors and Nazi goons, not to mention Scully as a glamorous 1930s spy in a red dress.
