Famous actors/Actresses in Horror/Sci-fi Films before they were famous

OK so I am a fan of B Horror Movies and Science fiction especially from an insomnia addled adolescence when all you could see on cable at 2 in the morning were B Horor Movies, Science Fiction Movies, or Softcore Porn. Sometimes you wuld even get a crossover like Frankenhooker which would fall into Multiple categories at once. I can't believe how many now famous actors I've scene doing these. I saw an episode of Red Shoe Diaries (Soft Porn) with Matt LeBlanc (Pre-Friends). Here are some others I know of some I've seen some I haven't in no particular order:
The Burning (Jason Alexander, Ned Eisenberg, Holly Hunter)
Lepricaun (Jennifer Anniston)
Parasite (Demi Moore)
Troll (Julia Louie Dreyfuss)
Friday the 13th (Kevin Bacon)
Nightmare on Elm Street (Johnny Depp)
Nightmare on Elm Street 3 (Patricia Arquette)
Texas Chainsaw Massacre (John Larroquete was the voice of the narrator)

Does anyone know any others?

how about ol jack? Jack hes been in quite a few b movies of which i can recall at the moment he he rock on Jack!!

 

"The Terror" Jack Nicholson and Boris Karloff I forgot that one. Jack was in quite a few Roger Corman flicks.

Here's one to prank your girlfriend with:
"The Texas Chainsaw Massacre: The Next Generation" starring Matthew Machonohay and Renee Zellwiger. It exists it's on DVD and they both tried to sue to get an injunction. Here is how the prank works. On your way home stop at the video store and pick up the movie. Then call your girlfriend on the phone and tell her you are bringing home a Matthew Machonohay Renee Zellwiger flick. While she's at home thinking you're you're a sensitive guy bringing home the chick flick you know what's in the bag. Now how your girlfriend is going to react depends on how well you know each other. Mine would laugh her ass off. You can also use this prank on your guy friends because of the mental connotations are the same but different.

Aw and I was just going to mention Johnny Depp in Nightmare On Elm Street but I was beat to it! lol XD
There's also Chris Sarandon (Susan Sarandon's ex) who was the detective in Child's Play (the first Chucky movie and imo the only good one!), and would later on voice Jack Skellington in The Nightmare Before Christmas and Kingdom Hearts, lol.

 

Nice one. I just saw the movie "Evil Bong" and on the bonus features the director shows a 4 minute montage of movies he's done with famous people back in the day here are some from his list:
Prison (Viggo Mortenson)
Cannibal Women (Bill Mahar)
The Pit and the Pendulum (Lance Henrickson)
Meridian (Sherilyn Fenn)
Metal Storm (Kelly Preston)
Trancers (Helen Hunt)

Two I remember that he didn't make that he didn't make but to me deserve to be mentioned:
The Texas Chainsaw Massacre II (Dennis Hopper did it right after Blue Velvet Yeah I know he was famous then too)
Leatherface The texas Chainsaw Massacre III or IV (I don't remember which) (Viggo Mortenson. God he made alot of these craptastic classics.)

Leslie Nielsen (from Airplane, Police Squad movies) was in "Forbidden Planet", 1956.
Micheal Landon (from Bonanza and Little House tv series) was in "I Was a Teenage Werewolf", 1957

 

Nice and wasn't Steve McQueen in "The Blob". Also Charles Bronson was in the Original "House of Wax" with Vincent Price credited under his birth name.
