Visible crew/equipment: In the toilet scene, you can see a camera reflection.
Continuity mistake: Charlie has set up a "security system" on the right side of the bed. When a double slaps Lindsay's hand, she goes over to a chair on the right side of the bed and the security system has vanished completely. It reappears when she returns to bed.
Revealing mistake: When Charlie and Lindsay are having sex, almost when they're done, a horse gets into the bed. The horse disappears too soon.
