The following is part two of Clatto’s ranking of the hottest actresses working in the horror, sci-fi, and fantasy genres as selected by my discerning penis. Unlike most scream queen lists, this one does not include starlets from yesteryear, but instead focuses on women that are currently stroke-worthy working.

Rank was determined by the actresses’ looks, body of work, and likelihood of continuing to work in the genres. Feel free to argue and comment (to see #20-to-#11 go here). Now, check out #10-thru-#1:

10. CHRISTA CAMPBELL

If you’re the kind of guy who enjoys watching movies with his penis, then you’ve probably sat through stinkers such as Mansquito and 2001 Maniacs: Field of Screams just to catch a glimpse of busty, 5-foot-8 stunner Christa Campbell.

The 38-year-old actress—and 2007 Playboy cover girl—has appeared in over 50 movies, usually in criminally small supporting roles. To her credit, she’s not afraid to steal scenes with her God-given gifts—as seen during her nude cat-fight with Amber Heard in the absolutely awesome Drive Angry 3-D.

Campbell will, however, be front-and-center in Grindstone’s shape-shifter thriller Hyenas and Nu Image Films’ upcoming theatrical 3-D release Spiders.

9. ODETTE YUSTMAN

Odette Yustman doesn’t have a lot of creds under her Hollywood garter belt, but the 25-year-old starlet whipped horror fans into a frenzy last year when her gorgeous posterior was featured on the poster of Rogue Pictures The Unborn.

Yustman, who is a mix of Cuban and Colombian linage, starred in the supernatural thriller as a woman tormented by the evil spirit of her unborn twin brother. The film earned over $42 million domestically and $76 million worldwide.

Just one year prior to The Unborn, Yustman played damsel-in-distress Beth McIntyre in director/producer J.J. Abrams’ monster hit Cloverfield. That film went on to earn over $170 million in worldwide coin.

Up next for the starlet is a turn in Anchor Bay/Studio Canal’s upcoming remake of the 1970 British abduction-thriller And Soon the Darkness. She and costar Amber Heard play American tourists on a bike-riding excursion in Argentina that goes terribly wrong when one of them is kidnapped. Check out images from the film here.

8. MARY ELIZABETH WINSTEAD

Mary Elizabeth Winstead made her horror film debut in 2005 with a bit part in Japanese director Hideo Nakata’s first American film The Ring 2. A lead role in James Wong’s Final Destination 3 followed in ’06 and quickly put Winstead on track for scream queen status.

Wong, impressed with Winstead’s performance, hired the leggy brunette for his remake of the 1974 slasher Black Christmas. The film was a commercial flop, but earned Winstead a nomination for Best Scream Queen at the Spike TV 2007 Scream Awards.

That same year, she scored the role of aspiring actress Lee Montgomery in Quentin Tarantino’s Death Proof. Though she doesn’t get much screen time in the flick, her character’s ditzy nature and short cheerleader skirt make her performance quite memorable … especially in the bathroom after the wife has gone to bed.

This year, Winstead was front and center in director Edgar Wright’s big screen adaptation of Byran Lee O’Malley’s graphic-novel series Scott Pilgrim VS. the World. The film got its ass kicked at the box office, but garnered good reviews for the 25-year-old starlet.

Up next for Winstead is a starring role in Universal Pictures remake of John Carpenter’s The Thing.

7. KATIE CASSIDY

Katie Cassidy, daughter to ’70s teen idol David Cassidy, made her horror debut in 2006 as Camilla Belle’s slutty BFF in Screen Gems remake of the 1979 classic When a Stranger Calls. That same year, she took a supporting role in Anchor Bay’s The Lost and nailed the lead in Dimension Films’ redo of the 1974 slasher Black Christmas.

A recurring role as demon-babe Ruby on season three of the CW’s “Supernatural” series followed in ’07. She was replaced after six episodes by Genevieve Cortese due to a reported salary dispute. Cassidy returned to TV in the 2009 CBS horror/mystery series “Harper’s Island,” in which she played the starring role of bride-to-be Patricia Wellington.

Cassidy scored her most successful film to date this year in Platinum Dunes’ reboot of Wes Craven’s 1984 frightener A Nightmare on Elm Street. The 23-year-old starlet played the role of Tina (renamed Kris for the remake), one of Freddy Krueger’s most brutal kills.

Cassidy’s favorite horror films include The Texas Chainsaw Massacre (old and new) and The Ring.

6. NATALIE PORTMAN

It may seem surprising to find Oscar-winner Natalie Portman on a list such as this, but the 29-year-old critic’s darling appears to once again be embracing the horror/sci-fi/fantasy genres long after starring as the iconic Queen Padme Amidala in George Lucas’ Star Wars: The Phantom Menace, and its sequels Attack of the Clones and Revenge of the Sith.

Portman, who played anarchist Evey Hammond in the 2006 Wachowski Brothers-produced dystopian-actioner V for Vendetta, spent most of the past four years starring in mind-numbingly dull indies and period pieces that we watched anyway in the hopes that she’d flash some skin ala Hotel Chevalier and/or Closer. This year, however, saw Portman lining up a series of projects guaranteed to please genre fans.

First up is director Darren Aronofsky’s acclaimed supernatural-thriller Black Swan, in which Portman plays a ballerina tormented by evil while competing to land the lead in a production of Swan Lake. She and Mila Kunis share a heated lesbian sex scene.

Portman is also serving as producer on the film adaptation of author Seth Grahame-Smith’s best-selling novel Pride and Prejudice and Zombies. She was set to star as the book’s heroine Elizabeth Bennet, but scheduling conflicts prevented her from doing so. Up next for the petite stunner is director Kenneth Branagh’s Thor and a possible role in Ridley Scott’s eagerly anticipated Alien prequels.

5. MILLA JOVOVICH

Despite having topped our list of The Ten Hottest Horror/Sci-fi Babes of the Past Decade back in January, Ukrainian-born actress/model Milla Jovovich continues to be one of the genre’s most prolific performers. The 34-year-old stunner’s most recent creds include last year’s creepy alien abduction thriller The Fourth Kind and the white-knuckle survival-frightener A Perfect Getaway.

This year, she reprised her role as Alice in Resident Evil: Afterlife. The film, shot in authentic 3-D, has grossed over $211 million in worldwide coin. Plans for a fifth installment are already underway.

Up next for Jovovich is a starring role in Julien Magnat’s Faces in the Crowd. She plays Anna Marchant, a woman suffering from prosopagnosia (inability to make out faces) after surviving a serial killer attack.

Jovovich made her sci-fi debut as the orange-haired, half-naked Leeloo Dallas in the 1997 Luc Besson actioner The Fifth Element.

4. JAIME KING

Jaime King first made a name for herself at age 15 modeling for Abercrombie & Fitch and posing for fashion mags such as Vogue, Allure, and—your favorite spank publication—Seventeen. Her first lead role in a film was that of kick-ass babe Jade in Lakeshore Entertainment’s failed 2003 adaptation of Michael Avon Oeming’s comic book series Bulletproof Monk.

King fared much better in 2006 when she played twin prostitutes Goldie and Wendy in Robert Rodriguez’s hardboiled actioner Sin City. Starring opposite Mickey Rourke, she goes topless during the flick’s best sequence “The Hard Goodbye.”

The following year, King took roles in the Canadian thriller They Wait and actor-turned-director David Arquette’s ode to old-school slashers The Tripper. She reunited with Sin City graphic-novelist Frank Miller in 2008 for his directorial debut The Spirit.

King scored a major one-two-punch in ’09 when she headlined Patrick Lussier’s surprise box office hit My Bloody Valentine 3-D and was cast to voice bounty hunter Aurra Sing in the George Lucas Cartoon Network show “Star Wars: The Clone Wars.” That same year, she cameoed in hubby Kyle Newman’s much-delayed ode to Star Wars geeks Fanboys.

This year saw King mentoring a slew of wannabe horror starlets on VH1’s reality-competition show “Scream Queens 2.” She will next star as a home-invasion victim in Darren Lynn Bousman’s Mother’s Day.

3. MEGAN FOX

Megan Fox hit instant stardom bent over the engine of a yellow 1976 Camaro in director Michael Bay’s 2007 box office hit Transformers. Her performance as  mechanically-inclined hard-body Mikaela Banes drew ire from fat and ugly women everywhere who watched helplessly as their man-child boyfriends stained their Optimus Prime Underoos.

She reprised the role two years later in Transformers 2: Revenge of the Fallen, solidifying her sexpot status early on in the film by straddling a motorcycle while wearing daisy-dukes. Unfortunately, her off-the-cuff criticism of director Michael Bay (she likened him to Hitler) in the media would see her replaced by Victoria’s Secret model Rosie Huntington-Whiteley in Transformers 3.

Fox headlined director Karyn Kusama’s (Aeon Flux) criminally underrated teen-horror film Jennifer’s Body in 2009. The role of high school man-eater Jennifer Check was written specifically for her by Oscar-winning director Diablo Cody (Juno).

Jennifer’s Body collapsed at the box office, earning only $16 million and a slew of bad reviews for Fox and Cody. The 24-year-old starlet didn’t fare much better in this year’s comic book-based Jonah Hex, despite playing the part of hatchet-wielding prostitute Leila in a corset cinched to give her an 18-inch waist. While it sucks that neither of these films found an audience, it does make the likelihood of seeing Fox in more horror/sci-fi projects all the better.

Fox will next play an angel-like creature trapped at a circus sideshow in director Mitch Glazer’s supernatural-romance story Passion Play.

2. DIORA BAIRD

Miami-born model-turned-actress Diora Baird and her mesmerizing 32-DD’s made their horror film debut in Platinum Dunes’ 2006 prequel The Texas Chainsaw Massacre: The Beginning. Roles in forgettable comedies and TV guest spots followed up until 2009 when Baird took a role in the unwatchable horror-spoof Stan Helsing. That same year, she scored a part in Paramount Pictures’ Star Trek reboot, but was cut out for not having blown J.J. Abrams.

This year, Baird appears to have finally given up on her childhood dreams of movie stardom and embraced the straight-to-DVD horror market. The 27-year-old starlet appears in Ghost House Pictures’ vampire-frightener 30 Days of Night: Dark Days and director Adam Gierasch’s Night of the Demons remake, in which she experiences demonic possession through anal sex.

Up next for Baird is After Dark Films’ violent bank-heist thriller Transit opposite LOST’s Harold Perrineau and “True Blood’s” James Frain. Her best work, however, can be seen in the pages of Playboy’s August 2005 issue.

1. AMBER HEARD

All the boys love Amber Heard … and for good reason. The 24-year-old Texas starlet has a penchant for going topless and a love of horror that began with the titular role in the little seen 2008 teen-slasher All the Boys Love Mandy Lane.

The film got stuck in distribution hell, but Heard went on to make a name for herself with memorable eye-candy roles in Summit Entertainment’s Never Back Down, Judd Apatow’s Pineapple Express, and Senator Films’ big screen adaptation of author Bret Easton Ellis‘ novel The Insiders—for which she went nude.

On the topic of nudity, she told FHM:

I did plenty of topless scenes too, which are in movies for no reason other than they’re topless. I paid that small price, which you have to do to go further. But I always knew what I was doing in a movie. If my role was nothing but that, I could make the decision, as an adult, whether to use it to my advantage or not.

Heard returned to horror in 2009 as Jesse Eisenberg’s sexy undead neighbor in Columbia Pictures’ horror comedy Zombieland. A bikini-clad role in Screen Gems remake of The Stepfather soon followed. This year, she stars alongside Danielle Panabaker in John Carpenter’s all-girl madhouse thriller The Ward and with Odette Yustman in Studio Canal’s tourists-in-trouble frightener And Soon the Darkness.

Next up for Heard is a ride-along with Nicolas Cage in Summit Entertainment’s supernatural road-rager Drive Angry 3-D. Directed by Patrick Lussier, the film stars Heard as a rough-and-tumble diner waitress out to help a man (Cage) take vengeance on the assholes that killed his daughter and abducted his grandchild.
