Mortal Remains (1972)

A group of jaded 1920s socialites defile the shrine of an ancient, evil sect and suffer horrific consequences as a result. Screened publicly only once, this film is considered lost as the answer print was badly damaged following its premiere screening. No other prints are known to exist, though fragments and still photos have surfaced from time to time.

Unfortunately the movie Mortal Remains is not yet available on Disney Plus.
