->''I warned you not to go out tonight.''
-->-- '''{{Tagline}}'''

A horror film from 1980. It was directed by William Lustig (''Film/ManiacCop'', ''Film/UncleSam'') and stars Joe Spinell in the title role.

It follows the exploits of the [[HeManWomanHater woman-hating]] and [[FreudianExcuse mommy issues]]-ridden psychopath Frank Zito, who wanders the streets of TheBigRottenApple from one brutal kill to the next, breathing heavily and babbling incoherently all the while.

The film's effects were provided by Creator/TomSavini, which includes the infamous "Disco Boy Scene" where a man's [[YourHeadAsplode head explodes]] from a close range shotgun blast.

The film also has the dubious honor of being one of three movies the late [[Series/SiskelAndEbert Gene Siskel]] had ever walked out on.

The year 2012 was treated to a remake that was produced and written by Alexandre Aja and which had Creator/ElijahWood star as the title character. It is mostly the same story, but with the twist that almost the entire film is [[UnbrokenFirstPersonPerspective shot from a first-person perspective]]. It also incorporates online dating.

!!These films provide examples of:
* AffablyEvil: Despite being a psychotic SerialKiller who murders women for their scalps, Frank is a really nice guy when he's not sitting in his room rambling.
* BigWordShout: ''"MOTHEEEEEEER!!!"''
* CreepyDoll: Various mannequins which wear scalps from Frank's victims that he keeps around his apartment.
* FreudianExcuse: Frank's mother was a prostitute who [[AbusiveParents beat him]] and would lock him in the closet when she was with her johns. That would certainly explain his awkwardness around the fairer sex, as well as why he kills women that remind him of her.
* {{Hallucinations}}: Frank starts having these when Anna hurts him at the funeral in the original. The remake has one as well.
* JobTitle: Well, Frank is certainly maniacal.
