Trivia / 10,000 BC

• Dark Horse Casting: The relatively unknown Steven Strait and Camilla Belle were cast in the lead roles because Roland Emmerich felt that casting names would detract from the prehistoric setting.
• Deleted Scene: An alternate ending for the movie revealed an elderly Baku was the Narrator All Along and told the events of the movie to the young generation in the village.
• Life Imitates Art: The movie shows mammoths existing when the pyramids are beginning to be constructed, which seems to be an incorrect presentation of ancient history. In reality this is accurate in regards to the fact that mammoths did still exist on Wrangel Island when the pyramids were being built. They just weren't in Egypt. Presumably the Almighty had these mammoths imported.
• Not Screened for Critics: Only a twenty minute excerpt was shown to journalists.
• Science Marches On: While the inclusion of the terror birds in this film was already a stretch even back then, for a while, it was actually considered possible (albeit heavily controversial) that Titanis (the last and one of the most famous of the giant terror birds) survived in North America until the end of the Pleistocene (circa 10,000 years ago), which wasn’t conclusively disproven by paleontologists until 2007, a year before 10,000 BC was released.
• Troubled Production: Roland Emmerich said that production was so exhaustive it made him consider retiring afterwards, as filming lasted 20 days longer than originally planned, had to add in a whole new location as he couldn't do helicopter scenes in Africa, and as he went to New Zealand for that, there was a problem with snow covering the place.
