Rob Pattinson: 'Twilight sex scene incredible'

Robert Pattinson has promised that a sex scene featured in the upcoming Twilight Saga: Breaking Dawn - Part 1 is "incredible".

Earlier this week, the British actor charged that those who illegally released unfinished photographs from the film are not true Twilight fans.

Speaking to MTV News, Pattinson promised that the vampire series' devotees will not be disappointed when they see his character Edward and Bella's (Kristen Stewart) sexual encounter.

"It's kind of incredible," he said. "I saw a prelim of it. [Director Bill Condon] has really, really good ideas for it."

The star also explained that the sequence proposed difficulties for Condon because it needed to evoke eroticism while also not violating the Motion Picture Association of America's content restrictions.

"It's kind of interesting, as well, having to do it in the context of PG-13," Pattinson asserted. "You can't do blatant… That's all been done in other stuff anyway, like saying, 'You just do it really, really fast!'"

His co-star Jamie Campbell Bower claimed earlier this week that Stewart is "perfect" in her role as a vampire.

The Twilight Saga: Breaking Dawn - Part 1 is to be released in UK and US cinemas on November 18.
