Trivia: Luke Ford, who played Alex O'Connell as an adult in this film, was initially signed on for a further 3 potential sequels and was destined to be the new main action hero of the franchise, succeeding Brendan Fraser, but the sequels were never made.
Trivia: A fourth film in the series, under the working title "The Mummy: Rise of the Aztec," was rumored for a number of years after the release of this third film due to its financial success. Brendan Fraser, Luke Ford, John Hannah and Maria Bello were reportedly all contracted for the film, while Antonio Banderas had been approached for the part of the villain. After significant progress had failed to be made by 2012, the film was quietly cancelled, and the series was eventually rebooted in 2017.
Trivia: The film made $400m, the lowest in the franchise, and had mediocre reviews.
Suggested correction: Actually, "The Scorpion King" has by far the lowest gross of the '99 "Mummy" franchise. Additionally, I don't see how reviews constitute trivia.
