Character actor Tony DiBenedetto (famous for being the Chicken Pimp in The Exterminator) has a non-speaking uncredited cameo bit at the beginning of the film exchanging mean glances with Jan-Michael Vincent. Meaning Tony was the reason Vincent was kicked off the ship they were both on. Thus setting the film in motion.
Because of this film Theresa Saldana gained a stalker. The Stalker stabbed her ten times in the torso. Theresa survived and went on to play herself in a Television Movie based on the events.
