Skarsgård plays vampire sheriff Eric Northman on the popular HBO series, but admitted that fans may be shocked at the dramatic change to Eric's demeanor after he suffers from extreme amnesia.
"This powerful character is just gone, it's not what we've built up over the past three years, it is just gone," Skarsgård explained, according to E! Online. "It's a lot of fun for me because it's the polar opposite of who Eric really is, he is lost."
"He's so sweet and cute, because he's got amnesia," Skarsgård's co-star Kristin Bauer, who plays Eric's right-hand vampire Pam, added. "So our whole dynamic has changed."
True Blood returns to HBO for a new season this summer.
