Summary

TheMarvel Cinematic Universeis beholden to its self-aggrandizing names for much of its success , but the series ' most far-famed performances were almost very dissimilar . It ’s no secret that the force of personality behind the MCU ’s most famous actors has been a massive part of its throttlehold on dada culture . It ’s unmanageable to imagineiconic amusing Scripture castingslike Robert Downey Jr. ’s Iron Man or Chris Evans ' Captain America being play by anyone else .

Yet for many of these synonymous function , the big name attached were almost very different , mayhap irreparably alter the MCU and its success . In some case , early iterations ofthe MCU ’s foundational Phase 1 movieswere almost made years earlier with different book , with a unlike star sequester to conduct . Other time , molding came down to the telegram at Marvel Studios , with last - moment cast choices being creditworthy for some truly phenomenal performances .

Gorr at the Altar of Eternity in Thor Love and Thunder

10Robert Downey Jr’s Iron Man

Almost played by Tom Cruise

Perhaps the tiptop of Marvel ’s casting choices is Robert Downey Jr. ’s Iron Man . The flagship theatrical role of the MCU , Downey Jr. ’s Tony Stark was the face of the franchise for a reason , with effortless personal appeal and believable struggles as the technical school billionaire superstar hero . At the fourth dimension , casting Robert Downey Jr. was a immense gamblefor Marvel , but one that give off tremendously . However , he was far from the only actor be to turn over for the office .

Cruise ’s Tony Stark would ’ve been an interesting guidance to go in

As far back as the XC , an earlier draft of the playscript forIron Manwas iterated upon long before the Marvel Cinematic Universe was ever conceived . This prototypic Iron Man movie was set to cast whizz histrion Tom Cruise in the role , featuring the nefarious organization A.I.M. and the bionic man M.O.D.O.K. as its primary antipathetical force .

9Dave Bautista’s Drax The Destroyer

Almost played by Jason Momoa

While Dwayne " The Rock " Johnson proved that histrion with roots in professional grappling could lead action franchises , Dave Bautista was able to set up a reputation as a honest Chamaeleon with his character as Drax the Destroyer . The charming , dewy-eyed - disposed Drax is one of the worked up pillars of the Guardians of the Galaxy , and without Bautista ’s impeccable comedic timing , experience with fight aspect , and ability to channel a genuine essence of gloominess repel the alien warrior ’s indigence for revenge , the team might not have worked as well . But Bautista well-nigh lose the role to another muscle - bound actor .

Interestingly , Marvel Studios initially approach Jason Momoa for the persona of Drax the Destroyer , only for theGame of Thronesveteran to turn the role down . Momoa expressed a worry about being type as simple brute quality should he accept the proposition , something which Bautista also spoke on after close his meter with the MCU . That being say , Momoa would go on to fiddle Aquaman in the DCEU , a hero characterized very likewise to Drax in his own movies .

8Chris Evans' Captain America

Almost played by John Krasinski

The de - facto loss leader of the Avengers and one of the earliest heroes for the MCU to prove , Captain America is tightlipped behind Iron Man in terms of overall grandness to the serial . Chris Evans ' performance as Captain Americais filled with subtle detail that make his sincerity and inherent good - nature so credible , a type of character that is n’t easygoing to deal audiences on . It ’s hard to say if anyone else would ’ve been able to make Captain America ’s " I can do this all Clarence Shepard Day Jr. " line slay as firmly as Evans did .

That being said , John Krasinski was a close second choice in the running for the role go into auditions forCaptain America : The First Avenger . At the time , Krasinski was more well - make out for his comedic stylings inThe Office , yet to become a major character in an natural action - packed blockbuster likeA Quiet PlaceorZero Dark Thirty . Eventually , Krasinski got to enter in the MCU with a abbreviated appearance as Mr. Fantastic inDoctor Strange in the Multiverse of Madness .

7Scarlett Johansson’s Black Widow

Almost played by Emily Blunt

Despite not fetch her own solo movie until far too late in the Marvel Cinematic Universe , Scarlett Johansson ’s Black Widow has been an incredibly important supporting eccentric throughout the first few phases of the MCU . Getting her start inIron Man 2 , Marvel ’s ultimate femme fatale seems tailor - made for Scarlett Johansson , an incredibly capable actress the wide range necessary to substantiate the super spy Natasha Romanoff . However , she was n’t the only one Marvel Studios had eyed for the function .

John Krasinski was n’t the only one in his family to narrowly debar being stray as a founding Avengers member . British Actress Emily Blunt was nearly cast as Black Widow , actually being Marvel Studios ' top choice for the heroine . Tragically , Blunt was ineffectual to obligate due to programming constraints in filmingGulliver ’s Travels , a rarely - commend dangerous undertaking funniness that certainly was n’t worth giving up Marvel superstardom for .

6Tom Holland’s Spider-Man

Almost played by Asa Butterfield

One quotation that must be given to the MCU ’s casting choice is their willingness to take chances on relative stranger . Tom Holland certainly was n’t a household name before being the quaternary live - military action histrion to take on the mantel of Spider - Man , but quickly endeared himself to audiences with his take on Peter Parker in no time at all . Holland ’s convincing high-pitched school performance , power to do some of his own stunts , and genuinely incredible acting skills all take in him his reputation as one of thebest Spider - Man actors .

Fellow Englishman Asa Butterfield narrowly suffer to Tom Holland in auditions forSpider - human being : Far From Home . Known for his breakout role as a child ace in the World War II period pieceThe male child in the Striped Pajamas , Butterfield proceed on to star in Netflix’sSex Education , making a name for himself on cyclosis . Butterfield is for sure a gifted comedic actor , but it ’s concentrated to reckon he ’d be able-bodied to outmaneuver Tom Holland ’s achiever as Spider - Man .

5Chris Hemsworth’s Thor

Almost played by Daniel Craig

Another relative unknown to be thrust into superstardom by their excellent Marvel performance , the MCU owe just as much to Chris Hemsworth as he does to it . After getting his start in Australian soap opera , Chris Hemsworth ’s performance as Thor managed to develop alongside the God of Thunder ’s journey throughout the films , going from a Shakespearean phantasy admirer to a comedic torpedo . Without Hemsworth , it ’s very possible that Thor might not ’ve had such a active journey through Marvel ’s many phases .

Marvel had actually approached Daniel Craig with the whim of recreate Thor before seeking out Hemsworth . The 007 star was no stranger to dribble an natural action franchise , butended up declining to continue focusing on his career as James Bond . With the release ofKnives Out , Craig has since proven he can do comedic as well as serious roles , give him one of the few role player who could ’ve stood a chance of retroflex Hemsworth ’s success .

4Winston Duke’s M’Baku

Almost played by Yahya Abdul-Mateen II

on occasion , an actor ’s performance in the Marvel Cinematic Universe can lift the popularity of a comparatively unknown Marvel quality to new heights . Such was the casing with M’Baku , appear inBlack Pantheras play by Winston Duke .

While Abdul - Mateen II lost out when it came to theBlack Panthercharacter and his subsequent appearances in three other MCU film , he still vex to roleplay in a major superhero cinema serial publication as Black Manta in the DCEU . Yahya Abdul - Mateen II has gotten another chance at MCU glory , however , lay to star as the titulary character reference ofthe upcomingWonder Manseries .

3Evangeline Lilly’s The Wasp

Almost played by Zooey Deschanel

Evangeline Lilly as The Wasp ranks among some of the most underrated MCU performances . While the character has only look in a modest four films , Lilly is able-bodied to instance Hope Pym ’s toughness and cynicism while alluding to a soft interior that Scott is able to tardily break into . Originally , Marvel ’s plans for The Wasp were very different , including a dissimilar actress being in thinker for the role .

Whedon ’s darling for the use was Zooey Deschanel

Before it was a sure matter that Scarlett Johansson would return forThe AvengersafterIron Man 2 , writer Joss Whedon was slap-up on the estimate of replacing the sole female member of the original squad with The Wasp . Whedon ’s favourite for the role was Zooey Deschanel , morefamous for her work in comedies likeElfandNew Girl . think The Wasp as run through the often quirky performances of Zooey Deschanel makes for an incredibly outre thought experimentation which , while an interesting idea , likely would n’t have worked as well as Lilly ’s take on the character .

2Zoe Saldaña’s Gamora

Almost played by Amanda Seyfried

Another role with an strenuous journey throughout the Marvel films , Zoe Saldaña ’s Gamora retain down an incredibly integral part of the Infinity Saga . Feisty and closed off but deep care for those snug to her , Saldaña was able to give incredible depth to what could ’ve well been a more one - dimensional assassin theatrical role in the hands of any other actress . Hopefully , her achiever in theGuardians of the Galaxytrilogy can landSaldaña a role in James Gunn ’s DCU .

Originally , Amanda Seyfried ofMean Girlsfame was offered the theatrical role of Gamora , but turn it down due to not want to be paint gullible . Having already act through layers of special effects inAvatar , it ’s easy to see why this was a non - issue for Saldaña . Seyfried ’s comedic chop would ’ve feel properly at habitation in theGuardians of the Galaxy , but it ’s unlikely that she could ’ve given Gamora better treatment than Saldaña did .

1Benedict Cumberbatch’s Doctor Strange

Almost played by Joaquin Phoenix

Benedict Cumberbatch had already carried a soda cultivation icon as Sherlock in the BBC series of the same name well before the firstDoctor Strangewas released . While there were some initial doubts as to whether he could pivot into achiever as an American laughable book character reference , Cumberbatch embodies Doctor Stephen Strange with flying colors , craft his carrying out with hauteur , neurosis , and an enrich emotional core . With cameo appearances in Spider - Man and Thor solo films , Cumberbatch ’s Sorcerer Supreme is one of the most predominant Marvel heroescurrently alive .

Cumberbatch was n’t the MCU ’s bit one choice for Doctor Strange , despite his achiever , with that honor go to none other than Joaquin Phoenix . A notoriously picky actor , Phoenix ended up turning down the character reference due to his hesitancy to confide to legion Marvel projects . While Phoenix turned in a glorious comic playscript execution in 2019’sJoker , his flair may have felt a little minute incongruous with the more lightheartedMCU .
