Revealing mistake: On the episode where Diana goes to New York and visits the hospital, it is filmed in the Reynolds Building at UMIST. Visible through the window is the Mancunian way with the car travelling on the left (not right) side of the road.

Continuity mistake: As Philip paints his parrot, its head can be seen half-painted. When Parker enters the room and the camera switches focus to him, the head can be seen in the background fully-painted. However, when the camera returns to Philip, the parrot's head is again only half-painted. (00:24:42)
