The film starts out with old black & white footage of World War I, along with the building of the alleged Britannic (although the number of propellers is wrong for this ship). The fate of the ship does not follow history, but the story is still engaging, despite this. As a English film, they seemed unable to portray the Irish without bias. Most Irish were not pro-British, but that did not make them pro-German. One man in the movie claims he is helping the Germans because of the Black and Tans murdering the Irish. The Black and Tans (vicious auxiliary police) were formed years after the events of this film. Amanda Ryan is believable, and has a brief nude scene when necessary to enliven the plot. John Rhys-Davies plays the ship's captain with the same subtlety that he showed in Sliders.
