Revealing mistake: When Graham and Stella are in bed, the camera shows only their arms intertwined as if he's lying on top of her. She's gasping loudly in response to his thrusting, but their arms never move back and forth to reflect this, so it's clear they're not really having sex.

Continuity mistake: When Graham is trying to electrocute his wife, he leaves the end of the black sticky tape on the opposite side of the bulb to the chain. When his wife tries to put the electricity back on, it's moved half way round the bulb. (00:30:00)
Robert Benham: This isn't exactly comfortable for me, I know you wanted this job. I suppose if we were rival princes, I could just have you killed. It would save a lot of politics.
Graham Marshall: It's not that easy to kill someone and get away with it.
