The film showing at the drive-in when Nancy goes on her rampage is Attack of the 50 Foot Woman (1958). The catering van in the dinner scene reads Arkoff and Corman, Industrial Caterers, a reference to American International Pictures producer Samuel Z. Arkoff and director Roger Corman (neither of whom was involved in the original Attack of the 50 Foot Woman (1958), which was released by Allied Artists).
