The official website is here: Click Me!!
And you can see a nice shiny trailer on there. ^_^
I loved the first movie, and I'm quite looking forward to this one too, and I hope it'll be better than the second movie. I mean, it was pretty good, but the kid annoyed the hell outta me and the CG version of the Scorpion King at the end was... well... not far off terrible!!
From the trailer alone this sequel already looks better!!
