“Twilight” star Mackenzie Foy battles an evil doll in “The Haunting Hour”

This week’s episode of R.L. Stine’s The Haunting Hour has the opportunity to satisfy two fervent fan bases.

For those rabid Twihards who can’t wait for Breaking Dawn — Part 2 to hit screens later this year, they’ll get another peek at the young actress who plays Renesmee, Edward and Bella’s half-human, half-vampire baby. And for Haunting Hour enthusiasts who were creeped out by Lilly D., the treacherous living doll who previously appeared in the two-part episode “Really You,” they’ll be able to see her in action once again.

In “The Return of Lilly D.,” Mackenzie Foy plays Natalie, a girl who goes to live with her grandparents only to discover that one of the dolls in their collection is alive and filled with evil intentions.

Going up against Lilly D. is no easy task, as another rising young star, Bailee Madison, learned the first time around. She has a way of committing terrible acts that hurt people while laying the blame on her owner, who tries in vain to convince those around her that the doll is actually alive.

Mackenzie thinks her character is up to the challenge, however. “Natalie is a sweet girl who loves to care for others, but if you mess with them, watch out!” the 11-year-old says.

STORY: R.L. Stine talks about his career, The Haunting Hour

Between this role and her high-profile turn in Twilight, Mackenzie is showing a flair for playing the supernatural. It’s an arena she enjoys, she says, because “it’s fun to be scared.” She’s already decided that acting is “absolutely what I want to do forever,” and that she hopes to eventually go into producing and directing.

In the meantime, however, Mackenzie says she is able to separate “work mode” from her regular life by pursuing her interests in painting, reading and Tae Kwon Do, a martial arts discipline for which she has earned the rank of senior red belt. Perhaps that’s appropriate right about now, as in Tae Kwon Do, the red belt is supposed to signify the color of blood.

R.L. Stine’s The Haunting Hour (“The Return of Lilly D.”) premieres at 5pm Saturday on The Hub.
