If I could shapeshift, I'd become a fly on the wall of the "True Blood" set so I could see how things are done. But thanks to Funny Or Die, fans are getting a behind-the-scenes look at the HBO series.

In the hilarious video "Method Shifting," Trubie newbie Janina Gavankar, who plays a new shifter and romantic interest for Sam (Sam Trammell), does her first scene with Marshall Allman, aka Sam's shifter brother, Tommy.

But Marshall is a method actor, who apparently believes he can actually shift into a dog or a chimpanzee. It's a confounding introduction to the show for Janina--until she shows Marshall how it's really done.

The actors are continuing the joke (or is it?) on Twitter. "@Janina you responsible for this monstrosity? Was supposed to be a closed set. #ifeelviolated," @MarshallAllman tweeted.

Search for the hashtag #ificouldshapeshift for more shifting fun. The video contains some NSFW content (although some fans might say not enough of it).
