The Behind the Scenes Video
I'd recommend it- there's more about how Jakyll is involved- including the name of the people/place he's working for/with, they let S.B. talk a bit about her Princess/Mummy character, you get to see some stuff that has some hints about just how butt-kicking they will make the Mummy herself, plus some other tidbits.

That is the link, it should take you to the video where they go behind the scenes. Way more convincing than the trailer, I'm afraid. It is more about the Mummy and less about a single stunt.
