 During the scene where Norma is leaving, she stands in front the car  from _Psycho (1960)_ (qv). The music playing in the background at  this part is also from Psycho. Janet Leigh (qv), who plays Norma,  played Marion in Psycho. The license plate on the car is also the  same as the second car Marion buys in Psycho, NFB 418, which are  Norman Bates initials.
