"Christopher Nolan has recently stated that selecting Robert Downey Jr. to portray Tony Stark in 'Iron Man' stands out as one of the most impactful casting choices in the annals of the film industry."

"By the decade's conclusion, similar acclaim may be bestowed upon the quartet recently chosen to embody Marvel's iconic superheroes in 'The Fantastic Four': Pedro Pascal, Vanessa Kirby, Joseph Quinn, and Ebon Moss-Bachrach."

Similar to Downey, each of these actors boasts recent involvement in high-profile productions: Pascal in "The Mandalorian" and "The Last of Us," Kirby in the last two "Mission: Impossible" installments, Quinn in "Stranger Things," and Moss-Bachrach in "Andor."

However, akin to Downey, none of them have previously starred in their own major studio action blockbuster prior to joining forces with Marvel.

Downey, undoubtedly, showcased an electrifying performance as Iron Man, propelling the Marvel Cinematic Universe forward for the following 11 years. He appeared in 10 films, collectively amassing $12.5 billion in global box office earnings, before Stark's demise in 2019's "Avengers: Endgame."

Following their departures, Marvel fans keenly feel the absence of Downey and Chris Evans' Captain America, who bid what might be their final farewells in "Endgame." These two characters epitomized the yin and yang of the early MCU: Stark, the bold and charismatic genius, and Cap, the steadfast and humble warrior, collectively forming the franchise's focal point.

Amidst the disbandment of the Guardians of the Galaxy, Spider-Man (Tom Holland) and Thor (Chris Hemsworth) taking breaks, and the heartbreaking loss of characters like Black Widow (Scarlett Johansson) and the late Chadwick Boseman's Black Panther, Marvel finds itself in need of new characters to anchor the most prosperous movie franchise in Hollywood's annals.

These revamped Fantastic Four could embody those pivotal characters, transitioning from the pages of comic books to the grandeur of the silver screen, a journey that began when Stan Lee and Jack Kirby conceived them in 1961, heralding the inception of the Marvel universe as we recognize it today.

Reed Richards (played by Pascal) and Johnny Storm (played by Quinn) serve as reimagined counterparts to Stark and Cap. Reed embodies Mr. Fantastic, a steadfast and humble genius, while Johnny, as Human Torch, exudes brashness and charm. Sue, as the Invisible Woman, develops an impressive array of powers in the Marvel canon. However, unlike characters like Captain Marvel or Scarlet Witch, she remains grounded, grappling with earthly, everyday challenges.

Ben Grimm (portrayed by Moss-Bachrach) embodies profound pathos, a resilient and amiable individual trapped within the seemingly monstrous form of the Thing, composed of rugged orange boulders. He shares similarities with the Hulk, yet lacks the uncontrollable rage, and with Rocket, but without the antisocial misanthropy.
