According to producer Merv Bloch the movie originally came with an especially shot intermission which he eventually decided to cut out. During the intermission Andy Warhol was shown sitting in a chair eating popcorn until the actual movie would continue again, which was meant as a sort of in-joke to Warhol's own films that often showed the most mundane things for an extended amount of time, like a person sleeping for several hours or a person eating something without anything extraordinary happening. The footage of this intermission is currently (2010) considered lost.
A remake starring Jennifer Lawrence and directed by Darren Aronofsky was in the works, but ended up canceled a month before production after it lost its financing (partially due to the covid-19 pandemic).
The film was refused a UK cinema certificate in 1971.
