- Ensemble Dark Horse: Bruno Ganz as Jurgen steals the movie and swallows it whole for breakfast. With tea.
- Evil Is Sexy: Liz. If it's January Jones, certainly.
- Fridge Logic: How could someone maintain a fake identity as a university professor for so long, when it would be easy for anyone with an Internet connection (like Bressler) to discover that the university had no such person on their faculty?
- But then the hotel security actually found "Martin B"'s photo on the Langemore University site. One could only assume that the university sysadmins were celebrating Thanksgivings Day a bit too hard.
- Hilarious in Hindsight: Bruno Ganz and Frank Langella both appearing in this film is quite interesting, considering both actors appeared in 1979 film adaptations of Dracula. Ganz played the role of Jonathan Harker in Werner Herzog's Nosferatu the Vampyre, while Langella played the title role in Dracula (1979) (which is quite fitting as in this movie Ganz plays a heroic role, while Langella conversely plays a villainous role; in addition Langella costars with Laurence Olivier, who played Van Helsing and in turn costars with Ganz in The Boys from Brazil).
- Moral Event Horizon:
- The assassins see their target has brought his children (about 6 and 8) to the party they intend to blow up. They don't even flinch.
- And later, after their original plan got derailed, one of the assassins intends to stab him in the back, right in front of his kids!
- Paranoia Fuel: Could you, in a strange country for the first time, have your identity stolen and your wife deny your existence just as Martin had? Some Nightmare Retardant: You couldn't. Unlike in the film, the embassy would be open over Thanksgiving and would have evidence in your favor.
