Fans of Henry Cavill have gone into a frenzy over claims that the actor may join the Marvel Cinematic Universe.

The 40-year-old actor has apparently been cast as Doctor Doom, an esteemed villain from Marvel Comics, in the movie.

In a tweet earlier this week, journalist Matt Reeves teased the casting on X, which was previously Twitter.

“From the greatest superhero Superman, to our greatest Marvel villain Doctor Doom…Henry Cavill,” tweeted Matt Reeves, accompanied a photo of Marvel CEO Kevin Fiege at Comic Con.

“Nah this would be the most insane casting announcement probably of all time #TheFantasticFour,” he said.

A film insider who goes by the moniker @MyTimeToShineHello on the social networking platform confirmed Cavill’s addition to the franchise but rejected his casting as Dr. Doom.

“He was offered something else, and he accepted,” they quoted Reeves’ tweet.

Fans weighed in on the probable casting, with suggestions ranging from Hyperion, an Eternal, X-Men’s Cyclops, Sentry, and Captain Britain.

If the allegation is true, it will be a big blow to the MCU’s rival property, DC, who abruptly ended the actor’s contract as Superman following the leadership transition in 2022.
