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

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

It follows the exploits of the [[HeManWomanHater woman hating]] and {{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 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.
