Random Trivia For This Title:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

- 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.
- 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.
- According to Zack Snyder, the filmmakers outfitted Henry Cavill in the Superman costume to see how well he fit the role. Despite the outfit bearing a lighter blue color and red trunks, no one laughed at Cavill. Snyder knew then that Cavill was right for the role.
- Aaron Smolinski, who plays a communications officer, previously played baby Clark Kent in Superman.
- 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.

- Henry Cavill naturally has a hairy chest and left it untouched for the shoot of this movie.

- 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. He said it would have been dishonest of him to use trickery while playing Superman and he wanted to push his body to the limits to develop his physique into one that was worthy of the character.
