Continuity mistake: When Mick and Maggie are talking in the kitchen after spending the night together, Mick pours himself a glass of orange juice and sets the carton down on the counter. The carton is initially in front of the glass, but then moves to sitting next to it.
Plot hole: Despite being obvious witnesses neither the prosecution nor the defense calls the gay couple (the ones that immobilized Roulet) to testify about their involvement (who called them, what they saw, etc).
Continuity mistake: After the case is dismissed, Mick finds a parking ticket on his car. When he gets in the car, he folds and puts it in his right inside suit pocket. When he gets home, he pulls it out of his left inside suit pocket.
