For Kristen Stewart and Robert Pattison, it was "love at first sight," "Twilight" director Catherine Hardwicke says.
Stewart, 20, and Pattinson, 24, play lovers Bella and Edward in the vampire romance movies and have long been the target of dating rumors but have not confirmed a relationship. They are currently filming the final "Twilight" film, the two-part "Breaking Dawn."
Hardwicke told Newsweek that she was initially unsure about casting Pattinson, a British actor, in the first "Twilight" film, which was the only movie in the series that she directed and which was released in 2008. She added that she has footage of the first meeting between the actor and Stewart on her dining room table.
"Kristen was like, 'It's got to be Rob!'" Hardwicke said. "She felt connected to him from the first moment. That electricity, or love at first sight, or whatever it is."
Hardwicke said she told Pattinson at the time: "'You've got to realize that Kristen is 17 years old. She's underage. You've got to focus, dude, or you're going to be arrested," adding: "I made him swear on a stack of Bibles."
Pattinson had addressed rumors of a romance with Stewart in a recent interview with Vanity Fair, which quoted him as saying: "It's just very traumatic."
When the "Twilight" mania is over, "the media will lose interest [in the relationship]," the magazine quoted him as saying. "There'll be nothing to say. It won't fit into a headline anymore. It won't fit into a template."
In November, the first image from "Breaking Dawn" was posted online and showed Bella's hand on a bed clutching feathers. In a scene from the books, the couple's lovemaking during their honeymoon becomes so frantic that they break the headboard on their bed and Cullen bites through a down pillow.
"Breaking Dawn" is directed by Bill Condon and its first part is set to be released on November 18, 2011. The second installment is scheduled to hit theaters on Nov. 16, 2012.
