Mickey punches Danny in the face, causing a split lip. The location of the blood on Danny's chin changes during the split shots.
Continuity mistake: The scene where Danny is lying on the sofa in the flat listening to music. Stacey throws down an envelope of money onto his chest. The banknotes spill considerably out of the envelope in the first shot. Two shots later and without either Danny or Stacey having touched the money, the banknotes are mysteriously tucked back inside the envelope.
