When the pygmies fall into the river after they blow up the bridge, look closely. As the right hand end falls into the ravine, one end is glowing from the blast, and one of the pygmies climbs on top of it and rides it down, hand waving, exactly like the scene from "Dr. Strangelove, or How I learned to stop worrying and love the bomb". Must be deliberate, and definitely worth a look.

While reading the Book of the Dead, Alex needs help translating the hieroglyph of a stork, which Jonathan gives to him. Jonathan needed help translating the same symbol in "The Mummy."

In the tomb, Alex knocks over the columns the same way Evie knocked over the bookcases in "The Mummy."

The scene where Imhotep is resurrecting the Scorpion King, he is hitting a big gong. A bald guy, in a loin cloth, hitting a big gong...this is a nod to the opening title of any 'Rank' picture.

This is mentioned on the commentary, but I've got to mention it here because it's great. The scene where Rick's stalking Imhotep and there's a sequence of shots alternating pitch black and Rick's face illuminated, was quite tricky. They set up the camera on a dolly track, shut off all the lights, then tracked backwards while Brendan Fraser walked forwards, with two guys lighting the scene by using flamethrowers either side of the camera, trying not to fall down the holes in the floor of the set all the time. Genius.

At the start of the movie, after Evie has been kidnapped, when Johnathan, Rick, Alex and Ardeth Bay are walking to the car, watch how Rick smiles at the fact that the world will be taken over...
