Factual error: When Debra Messing and Dermot Mulroney 1st arrive in London Debra goes to a pub to change her outfit, the shot showing the outside of the pub you can see an American style traffic lights eg walk, don't walk which are nothing like the English green man red man traffic lights.
Continuity mistake: In the scene where Debra Messing and Dermot Mulroney first arrive in London at the first party, Debra's jacket belt is undone when they enter through the door, then done up tightly when they are shot from a different angle, and undone again as those move from the room.
Nick Mercer: Close your eyes. Close your eyes. Close... Your... Eyes. You're safe. You can relax. I'm not going to kiss you. He's gonna be so sorry he lost you, so stop worrying. Forget the past. Forget the pain. And remember what an incredible woman you are. You do that and he'll realize what he lost.
Kat Ellis: Holy crap. You're worth every penny.
