Schizo 1976 is a slasher film directed by Pete Walker and starring Lynne Frederick.
Time Out wrote Walker and writer David McGillivrays most ambitious project to date attempts to shake off the lowbudget horrorexploitation tag with a move into more upmarket psychological suspense. If the formula is threadworn a trail of victimisation, sexual paranoia, and murder in the wake of the heroines wedding at least some effort is made to locate it rich middle class London. But things collapse disastrously in the second half. Caught between sending itself up and taking itself seriously, the film ends closer to the silliness of Francis Durbridge than to the menace of Alfred Hitchcock.
