Filmed in 3 days.
The movie that plays on the TV is "Nekro"
The names of the two characters are taken from two favorite films of A. Baez. Ana from Andrzej Zulawski's Possession (1981)
And Suzy from Dario Argento's Suspiria (1977). However, the character Suzy (played by Alyssa Ritchie) in "Entrails and Amour" is based off Ana from Possession.
As the film progresses and the story becomes more chaotic, carefully pay attention and you'll notice the editing will also become chaotic. The Chaotic editing consist of music skipping and/or replaying, black frame coming in and out of the films picture, unstable cinematography, voices become distant and less audible than before, as well as losing some color. The film is suppose to deteriorate just as the Suzy's story does.
