Shia LaBeouf defends ``real sex`` film role

Melbourne: Shia LaBeouf, who is set to do authentic sex scenes with Nicole Kidman in ‘Nymphomaniac’, has defended his latest film role, claiming he has "rules" when it comes to getting into a character.

He also insisted that he is not "completely out of [his] mind" when it comes to committing to a movie.

"There are rules," the Herald Sun quoted him as telling USA Today.

"I have ethics, I`m not completely out of my mind.

Shia, however, admitted that he does have limits with role immersion.

"But I don`t think there``s anything wrong with sex. Sex is beautiful if it``s done right. And I wouldn``t just do it for no reason. … Sex is different than love, and there is a separation, and that middle gap is what the movie``s about,” he added.
