I saw this movie a couple of months ago.

It started with some ship blowing up then this girl dying as a result, then later this assassin attempted to kill this other girl, but these two guys chased her through a street that looked like discount Blade Runner, then for some reason, this assassin turns into some kind of monster. Later the younger guy and the girl go to this lake somewhere and the guy says something about how he doesn’t like when sand gets in your eyes or something. At the end there was this big battle in a desert and for some reason they had dragged Christopher Lee into this and he had a swordfight with this lizard man who just jumped everywhere.

Can you guys help me out?
