The Mother (2003)

Continuity mistake: When we first see May just after Paula punches her, she has a vivid purple bruise under her eye. She gets the train home that same day and when she is looking out of the window, the bruise can hardly be seen. Once she is home in bed that night, the bruise is vibrant purple again.

May: Oh, Darren. This cigarette's making my chest all congested. I can't breathe.
Darren: What would happen if you did breathe?
May: I'd say, would you... would it be too much trouble... spare rooms... would you come to the spare rooms with me... would you.
