The drive-in theater seems to show Herschell Gordon Lewis' Blood Feast (1963), but it is not. The movie showing is actually La dama de la capa roja (1972) a.k.a. "La Dama Rossa Uccide Sette Volte." It was also distributed under the name "Blood Feast," which has caused some confusion.

The Turner Classic Movies network once paired an airing of 'New Year's Evil' with the film El demonio de la navidad (1980) for a holiday-themed slasher movie double feature.
