Robert Pattinson has said that it would have been impossible for the gory birth scene to have been toned down in Breaking Dawn - Part 1.
The latest installment of the Twilight Saga franchise sees Bella Swan's (Kristen Stewart) newborn eat her from the inside out, and is just one of a number of scenes that go beyond what fans have become used to seeing.
He told Premiere magazine: "It's hilarious. No movie this size dates taking those kind of risks.
"But since the craziest scenes are a big part of the story going forward, it was impossible to not have them included in the film... There was no way we would tone it down."
The 25-year-old added that his Cosmopolis director, David Cronenberg, will be amazed at his portrayal of Edward Cullen, saying: "I think he's going to enjoy certain scenes, like the one where I open her [Kristen] up by biting through her placenta.
"It was without a doubt the funniest thing I ever had to do. I’d raise my head up and I was covered with cottage cheese or whatever substance they put in there."
He also revelaed how the cast tried to make the birth scene as realistic as possible, adding: "Before filming the scene, [Twilight author] Stephenie Meyer, a midwife, Kristen and I sat down to talk to a doctor to decide where I was supposed to bite if this situation would ever occur in real life.
"The doctor looked at us a bit puzzled and said: ‘I don’t think you could ever do this in real life.'"
The Twilight Saga: Breaking Dawn - Part 1 is released on November 18.
