London, May 18 (ANI): Kate Hudson found it hard to film a violent scene with Casey Affleck in new movie ‘The Killer Inside Me’ because she couldn’t stop laughing.

Affleck spanks the actress, while lying semi-naked on a bed in the scene.

“There were a couple (of spankings) in there when I thought, ‘God, Casey!’ He got a bit of power behind it. It was definitely real,” the Daily Star quoted Hudson, as saying.

She added: “It depends on your sense of humour where you draw your boundaries. After about the 20th spank we all started to laugh because you become quite comfortable with the idea and it becomes about the technical side of things.

“I’ve known Casey for so long that you can’t help but laugh every now and then. I’m pretty comfortable with my body. I’m imperfect. The imperfections are there. People are going to see them, but I take the view you only live once, and, hey, I’m getting spanked today!”

Hudson plays the girlfriend of a psychotic killer, played by Affleck, in the film. (ANI)
