Schizo is a 1976 British psychological horror slasher film directed and produced by Pete Walker and starring Lynne Frederick, John Leyton and Stephanie Beacham.

Samantha tells her psychiatrist friend, Leonard Hawthorne, that Haskin was her mother's lover until he brutally stabbed her to death during an argument.

[citation needed] The release of Schizo (1976) was rushed to coincide with the anticipated success of Frederick’s highly acclaimed performance in Voyage of the Damned (1976).

[2] In The Monthly Film Bulletin, Tom Milne wrote "Not one of the happier Walker-McGillivray collaborations, Schizo starts off on the wrong foot with a truly hackneyed come-on (an awed transatlantic voice solemnly explaining the joys of schizophrenia), and thereafter trudges wearily into a morass of evasions and red herrings as the plot twists and turns in a frenzied attempt to obscure the fact, obvious from the very start, that beleaguered heroine and bloodthirsty killer are one and the same.

Deprived of any support from the script this time, Pete Walker's direction, all thump, scream and cut as shadows lurk and doorknobs turn – with each cliché heralded by a triumphant tremolo or bass boom from the score – reduces the whole thing to risible absurdity in which even the studiously nasty murders (Mrs. Wallace killed by a knitting-needle rammed right through her skull) are unconvincing.

"[3] Time Out wrote: "Walker and writer David McGillivray's most ambitious project to date attempts to shake off the low-budget horror/exploitation tag with a move into more up-market psychological suspense.

If the formula is thread-worn – a trail of victimisation, sexual paranoia, and murder in the wake of the heroine's wedding - at least some effort is made to locate it (rich, middle-class London).
