Alexander Skarsgrd says flying in True Blood was "childish" but "fun".

The actor is famed for his role as vampire Eric Northman on the popular HBO series. Alexander has recalled his favourite experience on the show so far.

"It's childish, but it was fun flying. I liked that. I want to do more of that. And the flashbacks have been fun. I mean, there are so many amazing moments on the show, but I loved shooting the stuff in Swedish the flashbacks and the Viking stuff was great," he told SciFi Now.

"I always think those are great moments, you get to learn so much more about Eric in those flashbacks, where he comes from and why he is like he is today, so those have been great to shoot."

Alexander stars alongside Anna Paquin on the show. The star finds the blonde beauty is a joy to work with.

"It's been great. We've had a lot of fun. That whole relationship has been so interesting, how over three years my character has been chasing her, and now suddenly I'm vulnerable and need her help," he said.

"It changes that dynamic quite a bit."
