Anna Kendrick had trouble shooting the wedding scene in 'The Twilight Saga: Breaking Dawn' because it was so cold.

Anna - who plays the role of Jessica Stanley in the vampire movie series - has revealed it was difficult to film the eagerly-awaited wedding scene between lead characters Bella Swan and Edward Cullen for the next movie 'Breaking Dawn Part 1' because of the freezing cold, and she thinks a lot of money will be spent digitally removing the breath.

She said: "Oh yeah it was I would say maybe 40 degrees in little dresses pretending that it is summer.

"I think lots of digital breath replacement will be a big part of the budget."

However, Anna, who stars alongside Robert Pattinson and Kirsten Stewart in the franchise, was thrilled to be part of the scene.

She said: "I'm only on set for a couple of weeks but, it's always really good fun."

Anna admits that the popularity of the films mean they have to go to special lengths to keep filming as secret as possible especially with the wedding scene.

She added to 'This Morning': "We are out in this forest that's like miles away from absolutely anything trying to shoot in secrecy trying to manage to keep any photographs from leaking and that kind of thing."

'The Twilight Saga: Breaking Dawn Part 1' will be released on the November 18 2011 with the final movie of the franchise released in 2012.
