Continuity mistake: In one of the early scenes where Baby, the pet leopard is introduced, you can tell that the scene was shot twice and overlapped. Baby's leash has an obvious gap in it, and the two halves move independently.
Visible crew/equipment: At Susan's apartment she explains to Dr Huxley that Baby responds well to music played on her phonograph. As she shuts off the record player there's a mirror in the background, and in the mirror, near the top, there's reflected a long piece of thick, black cable stretched horizontally, vibrating rather plainly.
