Insanity (1982) Synopsis & Summary

Back in 1965, bank clerk Terence Stamp's obsession with art student Samantha Eggar in The Collector culminated with her kidnapping. In Insanity, Stamp is once more unduly fascinated with a pretty young thing. This time, Stamp plays a film director, and the object of his desire is an actress, played by Corinne Clery. When she expresses disinterest, he turns violent. Insanity has none of the inherent artistic quality of The Collector; it sets flat out to terrorize the viewer, and in this it succeeds. - Hal Erickson, All Movie Guide
