Why is Brendan Fraser laughing?

The hugely successful 'Mummy' franchise was no doubt inspired by the adventures of 'Indiana Jones,' so it's fitting that 'Part III' lands in theaters only months after Indy's big return.

And in 'Tomb of the Dragon Emperor,' explorer Rick O'Connell (Brendan Fraser), the world's foremost mummy expert and ass-kicker, also adventures with his son (Luke Ford), with speculation the franchise will be handed off to junior.

Though this second trailer isn't markedly different from the first, it's got enough cool battle scenes -- and yes, even a fire-breathing dragon -- to warrant a good look.
