An odd little film based on an unpublished book by Creator/StephenKing, ''Sleepwalkers'' follows the story of Charles Brady (Brian Krause) and his mother Mary (Alice Krige), a pair of soul-sucking cat demons called Sleepwalkers. The Sleepwalkers have apparently incredible [[MasterOfIllusion powers of illusion]], but are critically weak to [[WeaksauceWeakness ordinary housecats]]. No, nothing is being spoiled here; they explain exactly what Sleepwalkers are in an expositional fake encyclopedia entry in the first ten seconds of the film.

The titular Sleepwalkers move into the town of Travis, Indiana and try to find a virgin to suck the life out of. Charles starts trying to seduce Tanya (Madchen Amick), who is [[InformedAbility apparently a virgin]]. Their relationship goes a little south when he tries to suck her soul on the first date, and a police officer shows up with an ''attack cat'' named Clovis. Charles is injured, and his mother begins a RoaringRampageOfRevenge. There are a few random car chases and murders to round out the movie.

It's also notable for being Stephen King's first collaboration with director Mick Garris.

* [[EvilDetectingDog Evil Detecting Cats]]: All cats hate the Sleepwalkers and swarm to their house to threaten them.
* EyeScream: Tanya manages to gouge Charles' eyes on two different occasions.
-->'''Charles:''' Tanya, I don't think you're entering into the spirit of this. Why don't you just think of yourself as lunch?
* GlamourFailure: You can see the Sleepwalkers true forms in mirrors. This, and their method of feeding, can make them a bit OurVampiresAreDifferent.
* [[AdultsAreUseless Humans Are Useless]]: While Tanya manages a lot of [[EyeScream eye-gouging]] on the monsters, the only named character who actually does anything useful is ''Clovis the cat''.
** Well the Shieff that came to Tanya's rescue did try, using one of the bear traps on Mary. Not his fault he was up against a supernatural monster.
* ImpaledWithExtremePrejudice: The sheriff gets body slammed on a picket fence.
* ImprovisedWeapon: Momma Sleepwalker kills a man ''by stabbing him with an ear of corn''.
* IncrediblyLamePun: One of the Sleepwalkers' notable abilities is to talk entirely in these during action sequences.
* {{Invisibility}}: One of the Sleepwalkers' powers.
* LargeHam: The Bradys. Though his mom chews the scenery, her hammyness rubbed off on Charles.
