On the Set of 'Vampire Academy!'

Vampire Academy, the big-screen adaptation of the first novel of Richelle Mead's best-selling series, is one of the most highly anticipated movies of 2014 -- and ET is on the UK set of the film, which promises plenty of romance and action!

In the addicting series, Zoey Deutch plays Rose Hathaway, a half human/half vampire who runs away from her school, St. Vladimir's Academy, with her best friend Lissa (Lucy Fry). When she is brought back by Guardian Dimitri Belikov (Danila Kozlovsky), the two develop intense feelings for one another when he begins to serve as her mentor, but face complications given their age difference and the fact that he's her instructor.

But according to Deutch, their romance runs far deeper than just the idea of forbidden attraction.

"Well I think there's a definite sense of 'Yeah, you want something you can't have,' but at the same time it does feel like from the moment they see each other, it is love at first sight," she tells ET. "There is some sort of undeniable connection that even when they do end up 'doing the do' -- or whatever you call it -- it's just not something that couldn't happen and therefore they're attracted to one another. I really feel like they are in love with each other."

"I love what's happening between me and Rose," echoes Kozlovsky. "It's very special, a very unique relationship, and I love it. It's sort of a lot of tension between me and Rose. I think it's gonna be very interesting for you."

However, the series' author Mead downplays the taboo nature of their romance.

"The idea for Rose and Dimitri's romance was one that was kicking around in my head for awhile. It's difficult being a former teacher to be writing about a student and a teacher who have a romance together -- because we're always taught that that's a very wrong thing -- and certainly it absolutely can be in that situation, so I'm certainly not encouraging that in people," she explains. "The age difference isn't that great between them. Mainly, you know, what the romance's big point is, [is] it's about love that has to challenge society's ideas -- that's what they're facing, and that's what it comes down to."

As for if the film stays true to the book, Mead says that she was pleasantly surprised by the faithfulness of the adaptation.

"What surprises me the most is how true it [the script] is to the book. I came in fully expecting, 'OK, we're going to slash and cut and change all kinds of things from the book to the script,' and [screenwriter] Daniel Waters just did an amazing job. He's got all the main parts of the books -- all the main beats are there -- all the parts from the characters we love, he's got all of those. He really gets it. He gets what I was trying to do with the balance of action and romance and humor."
