As of my last update in October 2023, "Superman: Legacy," set for release in 2025, has not yet premiered, so it is impossible to determine whether it will be a hit or a flop. Directed by James Gunn, the film aims to reboot the Superman franchise and has generated significant anticipation among fans. Box office success will depend on various factors, including marketing, critical reception, and audience engagement upon its release. Keep an eye on upcoming reviews and box office numbers for a clearer picture after its debut.

Henry Cavill is no longer Superman primarily due to a change in leadership at DC Studios. After James Gunn and Peter Safran took over, they decided to reboot the DC Extended Universe, leading to a new direction for the Superman character. Cavill's return was initially announced for a cameo in "Black Adam," but plans changed, and the new vision did not include him. As a result, Cavill's portrayal of Superman was officially concluded, paving the way for a new actor to take on the role in an upcoming reboot.

Lex Luthor's hatred for Superman primarily stems from his perception of Superman as a threat to humanity and his own ambitions. Luthor views Superman's immense powers as a challenge to human authority and independence, believing that reliance on an alien savior undermines human potential. Additionally, Luthor's personal vendetta is fueled by jealousy and resentment, as he sees Superman as a symbol of everything he despises—heroism, power, and moral authority—which ultimately drives him to plot against the Man of Steel.

"Smallville" is a television series that explores the early life of Clark Kent before he becomes Superman. It focuses on his teenage years in the fictional town of Smallville, Kansas, detailing his struggles with his powers, relationships, and identity. While it offers a deeper look at his character and background, it is not the "real story" of Superman but rather a reimagining and expansion of his origin. The Superman mythos itself is rooted in comic books, particularly those created by Jerry Siegel and Joe Shuster in the 1930s.
