It's Alive was a 1974 horror film written and directed by Larry Cohen. In the movie, a couple's infant child turns out to be a vicious monster that kills when frightened. Notable talents involved in the movie were Bernard Herrmann for the score and Rick Baker for makeup and puppet effects.

The film was re-released in 1977 with a massive TV publicity campaign which featured a trailer showing a basinette which slowly revolved to show the creature's claws hanging out one side.

Surprisingly, in view of the fact that some countries (Finland among them) banned the film, the movie received a PG rating in the United States. It was also originally given an 18 certificate in the UK, but was recently lowered to a 15.

Two sequels followed: It Lives Again in 1978 and It's Alive III: Island of the Alive in 1987. Like the original, both were written and directed by Larry Cohen.

As of spring 2007, a remake is being filmed in Bulgaria, with Bijou Phillips as the creature's mother.

This film was #43 on Bravo's 100 Scariest Movie Moments.

The monster in this movie originally appeared in director Larry Buchanan's earlier movie Creature of Destruction (1967) (TV).

Bernard Herrmann entitled the music cue where the milkman meets his demise "The Milkman Goeth".
