->''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 streets of TheBigRottenApple from a brutal kill to the next, breathing heavily and babbling incoherently all the while.

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 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 shot from a first-person perspective. It also incorporates online dating.
