'True Blood' star Alexander Skarsgard goes nude for 8 hours on set

True Blood star Alexander Skarsgard literally spent eight hours naked on set, according to his co-star.

While everyone involved with the show is pretty much tight-lipped about what to expect in season four, E! reports that show's creator Alan Ball will have Skarsgard stripping down again.

"He was once naked for about eight hours and he's completely comfortable with it," the Daily Telegraph quoted Kristin Bauer, who plays Eric's devilish sidekick Pam, as saying.

"He's Swedish. My husband's band toured in Sweden and he said that just how it is. There's no puritanical background there."

Speaking to Rolling Stone magazine in September, Skarsgard commented on his attitude to being naked on set. Referring to the 'sock' used to cover actors modesty, he said: "I don't want a sock around it, that feels ridiculous. If we're naked in the scene, then I'm naked. I've always been that way."
