Could We Be Seeing Surtur In ‘Thor: The Dark World’?

Apparently a recent casting call has gone out revealing that producers are looking for extras that are particular experts with fire. Could this possibly mean in the sequel we may see Thor and company exploring Muspelheim, the realm of eternal fire, home of the fire demons and their ruler Surtur?

It’s not entirely unlikely being that he was featured in the video game for the original movie. Maybe we will Thor travelling across the different dimensions? Maybe not. This is entirely speculation right now but would this be something you would want to see?
