Trivia: According to director Stephen Sommers, Universal Studios phoned him the morning after the film's release and said "We need another one."
Trivia: The scene where the library shelves fall like dominoes was not CGI, and was done in one take - a reshoot would have taken an entire day to set up.
Trivia: Production designer Allan Cameron found a dormant volcano near Erfoud in Morocco where the entire set for Hamunaptra could be constructed.
Trivia: Almost all of the muzzle-flashes in the film were digitally added, for two specific reasons. The first being that sometimes muzzle-flashes simply don't show up on film. And second, due to the environment in which the film was made, sand would constantly jam-up the guns the production was using, often in the middle of a shot.TedStixon
Trivia: The soldier-mummies were not in the original script. Instead, Jonathan would accidentally bring to life a giant statue. It was cut for the enormous cost the computer effects for the statue would have incurred, and replaced with the soldier-mummies, since they could be accomplished mainly with old-school suit effects mixed with only minimal CG for specific shots.TedStixon
