Goof--Though the scene is set in Moscow, the text displayed by the entrance computer is Dutch.
- At minute 15 there is a brief shot of ID-information, the bulk of the text is in Dutch. The height of the character is mentioned in the imperial system, in Holland we use the Metric system. Furthermore, all headings include De (the) which is uncommon on ID cards etc. Another translation error is "De hoogte", which should be "Lengte" (length), and on the bottom the status of "Current" is translated as "Stroom", which is actually current in the electrical sort (measured in Amps). That one should read "Geldig" if pertaining to the status of the document.
Trivia--Number 47: The room Will is taken from is room 147.
- The entire 'train' set, as well as the exterior CGI shots of the train were recycled from the fourth season opener, "Authorised Personnel Only (Part 1)".
