In a Black Adam cameo, Henry Cavill explains why he chose the Superman suit.

Henry Cavill has discussed why he chose the Man of Steel outfit for his Black Adam appearance and the "powerful moment" he experienced when donning the Superman suit once more.
Cavill appears in Black Adam's post-credits scene with the recognisable blue and red outfit used by Superman. The actor discussed why he chose to wear the Man of Steel attire for his comeback in an interview with Josh Horowitz on the Happy Sad Confused podcast, according to Variety. He also opened up about the emotional resonance of the clothing and how he felt when he put it on again for the first time.
"For me, it was a very moving time. I wasn't sure how I would feel—whether donning the Man of Steel outfit again would have a strong emotional impact, "said Cavill. "Because of the nostalgia associated with the suit, I specifically chose that one. It was crucial for me to be present at that time and to enjoy it. That ranks among my career's pinnacle moments. It's wonderful to get the chance to wear it once more."

According to recent speculations, a Superman sequel starring Cavill is already in development, so it won't be long until he might be stepping out in the costume once more. On Instagram, the actor also made his return to the DC Extended Universe official announcement and assured fans that their support and endurance would be "rewarded." Since then, he has talked about the character's "promising future."

"I have a deep connection to the character. Now five years have passed. I never lost faith, "On his half-decade wait to hear whether he will be playing Superman once more, Cavill spoke. "It's incredible to be discussing it once more right here. The protagonist has such a promising future. I can't wait to tell a tale about a Superman who is incredibly happy."
For years, Dwayne Johnson has made references to a fight between himself and Superman, telling fans that the two will "definitely" square off in a future film. Although there isn't a crossover movie in the works as of yet, if Black Adam does well at the box office, it might not be too long before that super-powered confrontation makes it to the big screen.

In our assessment, IGN concluded that Black Adam was regrettably underdeveloped and that many of its concepts were unfinished. But Johnson's all-in mindset ought to guarantee that we'll see more of him in the future.
