Random Trivia For This Title:
- Both director Bryan Singer and actor Brandon Routh expressed interest in reprising their positions from Superman Returns on this film; Singer had originally outlined several sequels to follow his story, and Routh was contracted as well. When Warner Bros. announced this film as a "clean reboot" from Singer's film, Routh still expressed interest in returning before Zack Snyder declared that this movie would have no ties to any previous cinematic incarnation of the character.
- According to David S. Goyer, Superman's costume is defined in this film to be an undergarment: "All the battle armor goes on top of the suits. But since Superman's a refugee, his outfit doesn't have that gear, and would make him defenseless on his own Kryptonian turf." This is also a nod to pop culture's running joke that Superman's costume appears to be underwear.
- When Superman learns to fly, he has a short flyover towards the camera. This is an homage to previous movies in which Superman would fly over the Earth and then smile at the camera.
- Initially, the original ending was supposed to be Superman throwing Zod into the Phantom Zone, but Zack Snyder and David S. Goyer decided to have Superman killing Zod instead. Snyder proposed it in order to set up Superman's classic "never kill" motto. He wanted it to be brutal and jarring, so that it would forever keep in Superman's mind.
- Matthew Goode, Armie Hammer, [?] Matt Bomer, Joe Manganiello, Zac Efron and [?] Colin O'Donoghue were on the final shortlist for the lead role. Henry Cavill was finally cast. He was the front runner to play Superman in another [Superman] movie (working title: flyby) but the movie failed to be greenlit and Brandon Routh was cast in Superman Returns instead. Cavill was also runner-up to ~2655~~ for the James Bond role in Casino Royale, Christian Bale for Bruce Wayne/Batman in Batman Begins.
- The final confrontation between Superman and General Zod was filmed in Chicago's Union Station. At the end of the fight, Lois Lane runs down the station's long staircase. This same staircase was the scene of the final gunfight in The Untouchables (1987), starring Kevin Costner, who plays Pa Kent.
- To completely distinguish this film as a new film separate from previous ones, the iconic "Superman Theme" by John Williams wasn't heard. This is the first Warner Bros. [Superman] film to not incorporate Williams' score from Superman.

- Superman's Kryptonian family name El is one of the Hebrew names for God, one of many savior allusions in the character's mythos. This comes from the original comic writers Jerry Siegel and Joe Shuster, who, being Jewish, would have been familiar with this trivia as part of their cultural heritage.
- Henry Cavill refused to take steroids to muscle up for the role. He also refused any digital touch-ups or enhancement to his body in his shirtless scenes.

- Ben Affleck turned down directing the film because he wasn't experienced in visual effects shots: "A lesson I've learned is to not look at movies based on budget, how much they'll spend on effects or where they will shoot. Story is what's important." He will appear as Batman in the sequel.
- The Kryptonian ship had one pod left open before Clark entered. It was revealed in a separate comic that the ship was once occupied by Clark's cousin Kara Zor-el, better known as Supergirl. This has led to speculation that she will appear in a later film.
- Director Zack Snyder said that he really wanted to include a shirtless scene of star Henry Cavill in the film because throughout the film, you see him in a form-fitting body suit where he appears extremely muscular. He said the audience would think it was all rubber muscles, but it was important to show them it was indeed Henry Cavill's body in that suit and that it was all real.
