Opening Title appears 40+ minutes in.
Originally the butcher character had lines, but after much consideration, the lines were cut.
When filming first started, the character of Mark Moses was originally played by Addison Chapman, but Balli retooled the project and thought that Chapman would be more suitable as the villain instead.
Sect is based on a short film of the same name Balli created in 2019.
Due to Covid restrictions and Balli's heart surgery, Balli and Apaydin had not seen each other in 2 years prior to a couple days before their first scene.
