In this 1974 horror film written, produced, and directed by Larry Cohen, diaper rash... turns into diaper rage.
Los Angeles PR executive Frank Davis (John P. Ryan) and his wife Lenore (Sharon Farrell) are overjoyed at the imminent arrival of their second child. Unfortunately, their baby... comes out a little odd. And it turns out to have a nasty habit of killing when it's scared. Which is pretty much all the time.
Followed by two sequels, It Lives Again (1978) and It's Alive 3: Island of the Alive (1987), as well as a very poorly-regarded 2008 remake.
Not to be confused with the show about fermentation on Bon Appétit.
This movie contains examples of:
- All There in the Manual: The novelization provides background as to why the baby turned out so screwed up (Lenore had been using experimental fertility drugs shortly after she stopped taking birth control pills).
- The Atoner: Frank reappears in the sequel trying to atone for his actions in the first film by helping other parents of mutant children, though unfortunately this results in a Sudden Sequel Death Syndrome about halfway through.
- Cat Scare: While Frank is unscrewing a basement light bulb to change it, something emerges from behind him and touches his shoulder. It's a large papier-mâché doll tumbling from a shelf.
- Corrupt Corporate Executive: The company behind the fertility drugs causing the mutation wants to cover it up, and orders the babies terminated so they won't be held liable.
- Downer Ending: Frank manages to find an emotional connection with the baby, but the military kills it minutes later. Not to mention his wife has been driven insane due to the whole ordeal, and another mutant baby has been reported born in Seattle.
- Down L.A. Drain: Where the baby is tracked at the film's climax.
- Enfant Terrible/Fetus Terrible: The entire premise of the series, the mutant babies are extremely deadly and hostile from the second they're born, and will viciously attack anyone they see as a threat... which is basically everyone.
- Oh, Crap!: Frank, waiting in the hospital hallway, sees an intern emerge from the delivery room... and collapse to the floor.
- What the Hell, Hero?: Frank and his wife give each other this exchange in regards to the infant. He wanted to kill it, while she wanted to hide it.
- Woobie, Destroyer of Worlds: The infant, whose homicidal rampage turns out to be driven by birth trauma and separation anxiety, and who longs only to be reunited with his family.
