The quiet drama of the "Equals" may seem on the other end of the spectrum from the epic action of "The Hobbit." Stars of the dystopian romance Nicholas Hoult and Kristen Stewart say otherwise.

The pair, plus "Equals" director Drake Doremus, sat down separately with MTV to discuss their upcoming movie and the tricky problem of shooting two people who are so different in height.

Actress Stewart, who rose to fame in the YA favorite "Twilight," described her new romance movie as a "very fundamentally basic, but really deep love story."

True enough, although "Equals" is set in a future society, the muted tone of the film is a far cry from the teenage-friendly action and angst of her former fantasy series.

"We are sort of supposed to represent these neutral un-individualized human beings, so when we find our femininity, and conversely his masculinity, it's good that we're so starkly different," Stewart explained, referencing the height difference between her and Hoult. "Because when I look up at him that is the embodiment of the male-female dynamic."

The conversation turned to "The Hobbit" when interviewer Josh Horowitz reminded her of a previous interview with MTV when her co-star talked about the immense height difference, saying shooting was "kind of like how they shot 'The Hobbit.'"

In the recent interview, Hoult continued to tease Stewart as he described the premise of the upcoming "Equals."

"You start with Kristen's character in the Shire," Hoult began jokingly. "And there's a ring. And they're going to write a book based on the movie, so that's exciting."

Even the director of the much-awaited drama got in a few choice words on the challenges of filming the couple.

"There's a lot of scenes where they're sitting on the ground which is more helpful," Doremus told MTV.

For her part, Stewart was a good sport about the ribbing.

"He's really a lot taller than me," Stewart admitted good-naturedly.

"Equals" follows the story of two co-workers Silas (Hoult) and Nia (Stewart) who live in a world where all types of emotion have been eliminated. Those who begin to feel are diagnosed with Switch On Syndrome or SOS; some are exiled from their safe reality. When Silas and Nia start to fall in love with each other, they entertain thoughts of escape to possibly find a world where the two of them can be together.

Hoult and Stewart star with Guy Pearce and Jacki Weaver.
