Plenty of people who dislike horror movies make the same complaint about horror as they do about porn: "the acting is terrible!'", "You're just waiting for the main event anyway" and "the budget on this is appalling!"
With that in mind, maybe it's not so much of a surprise that more porn actresses than you might think have appeared in mainstream horror movies... did you notice these adult stars when you watched these horror films?
Year of Release: 2010
Actresses: Ashlynn Brooke, Gianna Michaels and Riley Steele
Adult Movies: Pretty Little Lesbians, Young Girls with Big Tits 2 (Brooke), Asses of Face Destruction 4, Amazing Colossal Face Sitters (Michaels), Tara's Titties, Like Sister Like Slut (Steele)
You get more bang for your buck with a comic caper like 2010's Piranha, featuring three adult stars in one movie. They frolic around as bikini-d beauties for a short while before getting horribly munched and mangled by the killer fish, of course.
Year of Release: 1977
Actress: Marilyn Chambers
Adult Movies: Behind the Green Door, Insatiable
One of the very first actresses to move from porn to box office, legendary director David Cronenberg cast Chambers in his artsy number Rabid in the late '70s - totally worth watching if you're a fan of his (or hers!)
3. Smash Cut
Year of Release: 2009
Actress: Sasha Grey
Adult Movies: Masturbation Nation 3, I Wanna Bang Your Sister, Anal Acrobats 3
Grey has actually acted in many mainstream projects, such as HBO's Entourage and The Girlfriend Experience for Steven Soderbergh. In Smash Cut, she is a TV presenter who agrees to star in a horror movie inspired by the career of goremeister Herschell Gordon Lewis...
4. Zombie Strippers
Year of Release: 2008
Actress: Jenna Jameson
Adult Movies: Buttman at Nudes a Poppin' 7, Dirty Bob's Xcellent Adventures 35
Possibly the most famous porn actress of all time, Jenna Jameson gamely featured in Zombie Strippers alongside original Freddy Krueger Robert Englund and gave cinema a gory striptease for the ages.
5. The Human Centipede 3: Final Sequence
Year of Release: 2014
Actress: Bree Olson
Adult Movies: Rack by Popular Demand 3, Scooby Doo: A Parody
The third Human Centipede movie may have disappointed many hardcore fans by veering more towards comedy than horror, but Bree Olson's performance was a welcome addition to the deranged blend of blood and madness.
