David Slade talks about Kristen's dedication while filming 'Eclipse' - also mentions Rob

The substance was always bloody and meaty, but Slade says the pragmatics of the whole ordeal were anything but easy. He feels exhausted just thinking about the experience.

"It was a 50-day shoot, with many 16-hour days," he says.

To make things even more challenging, the cast was losing itself in its own Twilight cosmos. All actors have to surrender to their roles and inhabit their characters to some degree for the duration of production, so Slade was pleased his cast was taking the whole project seriously and sincerely.

Everyone was committed, he says. "Kristen, in particular, was very tough on herself."

Slade says because Stewart didn't pull from her own life and her own person to play Bella Swan, she found it personally demanding to find Bella's truth. "She would say, 'I don't know who Bella is to me.' In a lot of ways, I think she felt Bella was the antithesis to her, which presented a lot of challenges for Kristen. . . . She would beat herself up about it, because she wants to be there. She never wants to leave a scene undone.

"There were tears," says Slade. "But you move on and you keep going. . . . Even in rehearsals with Rob (Pattinson), there was a similar spiralling that would happen."

Actors are people. They get insecure, and any human being facing the weight of expectation surrounding Twilight would have to buckle, if only a little. To offset as much of the thespian obsessing as possible, Slade says he's learned the value of preparation.

He says he rehearses his actors as much as possible, so they're comfortable with the material and their characters, and he gets to focus on the minutiae of performance without the intrusive presence of a camera.
