Kristen Stewart wowed Twilight director Bill Condon with her “vampire orgasm”.

The 25-year-old actress famously starred as Bella Swan in the teen horror movie franchise.

Bill helmed the final two installments in the series – The Twilight Saga: Breaking Dawn – Parts 1 and 2.

And he says that while Kristen has attracted her fair share of criticism throughout her career, she consistently impressed him with her work ethic.

“I’d been a fan of Kristen’s before Breaking Dawn, and I loved working with her,” Bill told Vanity Fair magazine. “She’s incredibly smart and committed, she played such a range of emotions across a single film, from wedding jitters to death throes to vampire orgasm—I mean, if you can pull that off, you can do anything.”

Since Twilight, Bill has directed Mr. Holmes with Ian McKellen and Laura Linney. He is also helming the upcoming live action remake of Disney’s Beauty and the Beast, with Emma Watson and Dan Stevens in the lead roles.

But while Bill has been blasted by many peers for his decision to direct the Twilight movies, the filmmaker insists he was thrilled to have been given the opportunity to include references to some of his favourite horror flicks.

“One of the reasons I wanted to do Breaking Dawn was that it really was a chance to channel my love of classic horror films into this massive pop phenomenon,” he said. “In a lot of ways, the climax of Breaking Dawn, Part 1 is a recasting of one of my favourite films, James Whale’s Bride of Frankenstein. Bella’s death and rebirth represents Edward turning her into a monster, re-creating her in order to save her. It was something that I felt reflected my lifelong love of the macabre . . . to say nothing of the fun I had shooting a huge wedding cake made of bloody corpses. I’m glad they let me drop that in.”
