Some scenes were shot at Simon Fraser University, at the top of Burnaby Mountain outside of Vancouver, BC. Although Vancouver attracts frequent film business today, in 1972 this film was a bit unusual for being shot in what would become known as "Hollywood North."
Production was temporarily halted due to the death of Michael Sarrazin's father.
Due to Carol White's prior commitments she was replaced by Christine Belford in the role of Nicole Devon.
Christine Belford remembered in an interview that the area in Canada where this movie was shot on location at was freezing cold and almost completely bereft of any people outside of the film crew.
Announced in trade papers as "The Plastic Man."
