It's been five years since "Man of Steel" hit theaters and launched the DC Extended Universe. Love it or hate it, it's a film that has profoundly shaped the course of DC's superhero movies. So why not celebrate this milestone by learning a few interesting facts about Superman's latest reboot?
1. Henry Cavill has said that the physical training involved for Superman's two shirtless scenes was the most difficult part of filming. It didn't help that Cavill refused any steroids or digital enhancement, feeling those methods would be dishonest.
2. Part of Cavill's training regimen involved drinking five 1,000 calorie protein shakes per day.
3. Though Lex Luthor and Bruce Wayne wouldn't appear until 2016's "Batman v Superman," various corporate logos seen in the film allude to the existence of both characters.
4.Amy Adams is one of no fewer than eleven actresses and actors to have appeared on the TV series "Smallville" prior to working on "Man of Steel."
6. Ben Affleck was offered the chance to direct "Man of Steel" but declined, citing his inexperience with effects-heavy films. Affleck went on to star as Batman in several sequels and was at one point attached to direct "The Batman."
7. Gal Gadot was cast in the role of Faora but had to drop out after becoming pregnant. That clearly worked out for the best, as Gadot went on to play Wonder Woman in several DCEU films instead.
8. A promotional tie-in comic book revealed that the alien ship Superman encounters in the Arctic was actually carrying his cousin, Supergirl. Despite this, Supergirl has yet to appear in the DCEU.
9. In the scene where Zod first unleashes his heat vision, a small sign can be seen in the background that reads "Keep calm and call Batman."
10. "Man of Steel" became the first Superman movie not to feature the Jimmy Olsen character. It was rumored that Rebecca Buller's character was a gender-swapped Jimmy Olsen, but her name is Jenny Jurwich.
12. The film came under fire from the National Weather Service, which has long been combating the erroneous belief that highway overpasses are safe places to hide during tornadoes.
13. Several images and lines of dialogue are pulled directly from DC's Superman comics, including "Superman: Birthright," "Superman: Secret Origin" and "All-Star Superman."
