A Rumer grows in Hollywood

When you’re the daughter of a couple of the sexiest screen stars of their generation, going into the family business is a no-brainer.

“My earliest memories were from movie sets,” says Rumer Willis, daughter of Bruce Willis and Demi Moore. “I got to see my parents doing that work every day and I couldn’t think of a more fun job to have.”

Her new movie, the horror flick “Sorority Row,” is Hollywood royalty’s version of paying one’s dues. So was her last film, “The House Bunny,” and her role on TV’s “90210.”

“I don’t think I realized until I started working myself what it was that I’d been privileged to see, growing up,” Willis, 21, says of her parents. “I saw two actors who were in a place that I would want to be, someday, at the top of their profession.

“When I started acting, I had to realize that they were at a different level than me and that the roles would be smaller, that I’d have to work my way toward what they have. It was a conscious decision on my part to try and do this on my own.”

So while she still lets Mom and Dad read her scripts or listen to her audition, she’s determined to “make it by myself.”

As for “Sorority Girls,” she’s film-savvy enough to know where her character, Ellie, fits in.

“Somebody’s got to play the girl who can’t handle this situation at all,” says Willis. “That’s Ellie. She’s the one overwhelmed by all this.

“But I’m perfect for that. I barely got through ‘The Ring’ the one time I tried to watch it.

“It’s not blood that gets me. It’s the stuff we can’t see that freaks me out.”
