A bounty hunter from an extinct tribe is hired to undermine the power of an evil king, but the woman he is meant to kill is hot, and complicates things.
As long as it is taken for what it is, it will be entertaining. It is an action movie through and through, and must not be taken as having much of a link to a historical past. It's not serious, and not meant to be. It's packed with action, has a reasonable story and its lead character is spectacular.
A lot of people would take this as a direct prequel or spiritual prequel to The Mummy Returns (2001), but that perspective must not be kept in mind!
Visions of a past life lead a woman to an ancient treasure, but it is also sought by others to both raise the dead and an army.
While it would be unfair to say this movie stinks, it's not great. The computer graphics used in it are uncanny and intrusive. It has action for action's sake, and where a light bubblegum movie is what it is, this movie lays it on intentionally thick, making it aggravating. Fans of its predecessor, The Mummy - (1999 movie), will find the feelings instilled by it are not reproduced in this sequel. It is an obvious money-grab.
An ancient discovery in Egypt, from before the pyramids, is found to be a gateway to another world which is still kept as a slave planet by Ra, a self-appointed god who is an alien just trying to get by.
A fantastic movie. Not exactly mandatory. Perhaps elements of it don't feel like they have held up well, or maybe there has been so much excellent science fiction before, during and since its time.
