Continuity mistake: Near the end of the movie, Kate's hair is wet and she has a bloody nose. When she finds the platform again her hair is a lot dryer is and her nose is not bleeding.

Continuity mistake: The amount of dirt on George's helmet changes between shots after he gets covered in sewage.

Continuity mistake: The first train Kate boards (where Guy gets dragged off the train by a mysterious attacker) is one of the new Jubilee Line trains built in 1996. However, when Kate escapes from the train through the rear cab, the train has become a much older model built in the 1960s/70s. (00:21:00)

Kate: I don't know what to say. It's like a penis... just smaller.

Jimmy: Homeless people don't go missing, homeless people are missing.

Arthur: It depends which area you're in. If you're in the areas around Chinatown, there's a strange sort of seafood smell, whereas in Soho.
George: Oh wow wow wow stop right there! This ain't the fuckin' Discovery Channel.
Arthur: I'm just trying to educate you, that's all.
George: Trust me, there's nothing I wanna know about shit.
