The party-goers are all friends and family of Sahag Gureghian.
The script was written in one night (plus later rewrites) when the writer was eighteen years old, based on his own short story.
Actor Richard C. Sarafian was first choice for the role of Dr. Schill, but he recommended his friend Milt Kogan, who got the job.
The boy Jennifer is making out with at the party is 'Elizabeth Perry''s real life boyfriend, who came on set as a favor to her when the original actor had to leave since shooting went behind schedule.
Writer Sahag Gureghian started, but never finished, a screenplay for a sequel, which was called Jennifer's Not Dead.
