Robert Pattinson has revealed he "loved" filming the gory birth scene in Twilight: Breaking Dawn, which he thought was like a horror movie.
After vampire Edward (R-Patz) impregnates Bella (Kristen Stewart) she has to drink blood to stay alive, and then almost dies giving birth to their child.
Robert said: "It could have been an R-rated sequence - or a really ridiculous comedy sequence.
"We kind of shot it as an adult horror and then edited out the really gruesome bits. If you went on the set, it looked like a Saw movie, not a Twilight movie."
He adds: "There's literally been no blood in the films, except for single drops here and there. I walked in and Kristen was covered in fake blood and gore."
And the 25-year-old actor also really enjoyed shooting the honeymoon scenes on a remote Brazilian island.
He laughed: "I didn't have to spend ages taking my make-up off every day because I just jumped in the sea."
:: The Twilight Saga: Breaking Dawn Part 1 opens in cinemas on Friday, November 18.
