This 1982 horror film stars Joe Spinell and Caroline Munro.
Spinell (Rocky, Maniac) plays Vinny Durand, a New York Cabbie who fantasizes about making a horror film with scream queen/actress, Jana Bates (Munro). He travels to Cannes where she's being nominated and his obsession with Jana goes awry when her friends/associates start turning up dead. This isn't bad, The late, Spinell was great as the disturbed, yet sympathetic Vinny much like his Frank Zito character, he & Munro had good chemistry and there's some bloody/gory make-up effects. If you liked
"Maniac," you might like this.
