Continuity mistake: In the absinthe-fuelled scene between Liz and Alfie when they fall about each other on the reclining sofa, the stereo remote control is visible in all shots half tucked under the pillow. Until the end when Liz gets up and the shot changes angle, the stereo remote control has disappeared completely.
Continuity mistake: In the scene where Alfie picks up Nikki and her friends at the park on Christmas Eve, as he drives away - supposedly on a limousine (this happens just a few seconds before the 49 minute mark), you can see the car isn't a limousine but a standard-sized car. Also, just a few shots before that Alfie takes a drag from his cigarette but doesn't put it back in his mouth. Yet when he starts driving he has his both hands on the wheel and the cigarette in his mouth.
