I made this film my senior year at Wesleyan University with classic technology of 1975: Eclair, Nagra, Movieola flatbed.
And finally this (for me) daring revelation: it is based on the Julio Cortazar short story "Secret Weapons" (from his collection of short stories "Blow Up and Other Stories"). As the film has never been released, or screened at a film festival in the 40 years of its existence I guess it's time to let that cat out of the bag.
It stars Dick Bernstein, who was the only other undergraduate filmmaker making sync-sound 16mm movies. His film "A City Doctor", which was his take on Kafka's "A Country Doctor" made a big impression on me.
