'Schizo' (1976) - Pete Walker.

A pretty, nubile ice skater's (Lynne Frederick) impending nuptials to handsome businessman Alan (John leyton) attracts the increasingly malign attentions of a shadowy figure from her equally mysterious past! With gruesomely orchestrated set-pieces, an unusually attractive protagonist Pete Walker's twisted, Giallo-esque slasher remains a must-see for kill-happy horror fans! The gripping plot and strong performances are compelling, and the writer's brazen pilfering of an iconic scene from Dario Argento's 'Deep Red is certainly audacious, if not entirely original.
