Visible crew/equipment: After Agent Ballard enters the house and confronts Mr. Minor in the kitchen, the camera goes back to Agent Ballard. In the reflection from the oven, you can see a camera man holding his camera and filming.
Trivia: Before Dollhouse, Olivia Williams had a bit part as Moira McTaggert in X-men 3. She was showing a patient who had no conscience. Xavier then brought up the ethics of placing the conscience of one person into another which is what Ms. Williams does now as Ms. Dewitt in Dollhouse.
