- At least one version of the theatrical release contained no subtitles for the opening scene aboard the German submarine. This was possibly to increase dramatic effect, placing emphasis on the acting and visuals rather than the dialogue.
- The German version has a title card at the beginning, saying the movie is completely fictitious.
- The theatrical version contained some captions before the end credits, explaining that the Enigma was, in real-life, recovered by the British Royal Navy, and not by the American Navy as portrayed in this movie. The captions have been removed on the R2 DVD.
