Gerard Butler said that as soon as he read the word 'God' in the script to describe his character, he knew would have to embark on a huge bodybuilding process. He said he started his work-outs immediately because he plays a God in the film and 'wanted to make sure he looked liked one by the time shooting began.'
In Egyptian mythology, Set (also spelled Setesh, Sutekh, Setekh, and Suty) is a god of the desert, storms, disorder, violence, and foreigners. In Ancient Greek, the god's name is Seth. Ra employed Set on his solar boat to repel Apep, the serpent of Chaos. Set was also lord of the red land (desert), where he was the balance to Horus' role as lord of the black land (soil).
The architect of the tower dedicated to Ra says it's 2,220 cubits high, 1,015 meters or 3,330 feet. When the film was released, the tallest structure in the world was the Burj Khalifa, at 829.8 meters or 2,722 feet.
Lionsgate/Summit's exposure on the production budget is only around $10 million, because Lionsgate/Summit were able to recoup most of the budget via international pre-sales and Australia tax incentives.
In the film, souls pass to the afterlife by having their richness weighed on a scale against a feather by Anubis. In Egyptian mythology, the souls placed their hearts on a scale (as a symbol of the flaws and virtues), which why internal organs such as the heart were mummified. The movie apparently sets the version of mythology that is known today.
