to boot , there are a number of histrion whose contract with Marvel Studios are just about up . While a issue of these character can just be written out , which we can expect to see in next year’sAvengers 4 , some of other fiber are just too good to for good kick out of the MCU .

Though some worker like Robert Downey Jr. and Chris Evans may be on their way out , it does n’t mean that Iron Man and Captain America have to leave too .

With that in thinker , here are the13   Stars Who Should Leave The MCU ( And 13 Actors Who Should Replace Them ) .

Should Leave: Robert Downey Jr.

Robert Downey Jr. may be the lead of the MCU , but that is n’t always inevitably a effective thing .

think how well known Robert Downey Jr. is , he now charge Marvel load of money for every single performance , with every appearance cost Marvel millions more than the last one .

Considering this factor and the fact that his contract is up afterAvengers 4 , there ’s no denying that Robert Downey Jr. ’s time in the MCU is number to an end , for proficient or for big .

Hopefully , in the absence seizure of Robert Downey Jr. , Marvel can use the unreasonable money that they usually spend on his paycheck to amend the overall calibre of their film in other departments .

Replacement: Jeffrey Dean Morgan

Jeffrey Dean Morgan has become an incredibly popular player in recent years , primarily due to his office as Negan inThe walk Dead .

Because of this , not only would Morgan answer as an telling permutation to Robert Downey Jr. in the mantle of Iron Man , but he would also be able to drive sales , which is arguably the most important cistron on Marvel ’s mind .

TheWalking Deadactor was previously report to toy a larger role in the DCEU , set to play the alternating universe version of Batman inFlashpointfollowing his show as Thomas Wayne inBatman v Lucy in the sky with diamonds : Dawn of Justice .

Unfortunately , it looks like theFlashmovie will no longer watch over theFlashpointstoryline , so this may be the perfect opportunity for Jeffery Dean Morgan to jump ship from the DCEU to the MCU .

Should Leave: Natalie Portman

Black SwanandStar Warsactress Natalie Portman appeared as the fiber Jane Foster inThorandThor : The Dark World . Unfortunately , Portman really did n’t fit the theatrical role of Jane Foster well , becoming a flavourless love interest .

Whether this was at the demerit of Natalie Portman herself or at the fault of the writer and directors remain to be seen , but regardless , a numeral of MCU fans were disappointed with her lineament .

If Marvel wants to go on grow Jane Foster in the movies like they did in the comedian , perhaps a recasting is in order .

Replacement: Emma Watson

Harry Potteractress Emma Watson would be the perfect replacement for Jane Foster , especially if Marvel follows Jane ’s story line from the comics .

Recently in the comics , Jane Foster became the new Thor , wielding Mjolnir in the absence of Thor himself .

Emma Watson has proven herself clock time and time again to be a terrific actress .

to boot , she on a regular basis takes stands against unexploited distaff persona in movies as part of the feminist movement . Having Watson become the new Thor would do work both for Emma Watson ’s ideals and as an entertaining and believable casting .

Should Leave: Ross Marquand

Earlier this twelvemonth , Avengers : Infinity Warbrought the return of Red Skull , the HYDRA baddie fromCaptain America : The First Avenger .

Unfortunately , rather than bring back the original actor Hugo Weaving , Marvel replaced him withThe Walking Deadactor Ross Marquand .

Rather than adding anything to the function of Red Skull , Marquand jolly much just did a Hugo Weaving imitation .

While we did n’t really get too much of a probability to see his performance , it still felt flat . If Red Skull were to render in the MCU down the route , it would believably be for the dear if he was recast with a more viable player .

Replacement: Liam Neeson

Takenactor Liam Neeson would be the perfect replacement for Red Skull in the MCU .

Not only does he have the right geezerhood ambit to attend like an onetime , yet still physically capable version of Red Skull , but his act performances in the yesteryear would make him the perfect villain .

Neeson previously play a supervillain inBatman Begins , and he did a in truth fantastic chore .

Emma Watson in This is the End

If he were able to bring the same level of confidence in his evil actions that he had inBatman Beginsto the character of Red Skull , the   HYDRA villain could finish up becoming a better adversary than even Thanos .

Should Leave: Sebastian Stan

Bucky Barnes , the old warfare buddy of Steve Rogers / Captain America , has become an important part of the MCU sinceCaptain America : The Winter Soldierin 2014 .

In the near hereafter of the MCU , Bucky   has the electric potential to become   an even more significant character , as many sports fan foretell that he will become the next Captain America .

Despite this , something just does n’t clack with the current position that Bucky is in .

Despite being an implausibly vital character , Bucky ’s performance feel flat and unrelatable , which can be credited to both his writing and act .

If Marvel hopes to have Bucky take up the curtain of Captain America , a unexampled actor may be necessary for the role in orderliness to keep audiences entertain and buying ticket .

Replacement: Kit Harrington

Game of Thronesactor Kit Harrington ’s schedule is set to open up a lot more in about a year after the final season of the HBO serial .

Not only is Kit Harrington perfect for the part of Bucky , consider his telling carrying out as Jon Snow , but he also has enough star business leader to carry on theCaptain Americafranchise after the inevitable departure of Chris Evans .

Harrington ’s forcible appearance and personality would make an fabulously entertaining interpretation of Bucky Barnes .

While it would be lamentable to see Sebastian Stan leave the role , it would hypothetically be worth it to see Kit Harrington become the next Captain America .

Should Leave: Marisa Tomei

Though Marisa Tomei may be a fantastical actress , a number of Marvel buff are still having difficultness image her in the part of Peter Parker ’s Aunt May .

While the reasoning for Marvel ’s decision to cast her makes perfect sense , as they are hoping to invest by casting an actress in her 50 rather than one in her 80s to keep her around long full term , the cast occur at a cost .

Though Tomei gave a great performance inSpider - Man : Homecoming , it was still not credible enough forSpider - Manfans who adore the performance of Rosemary Harris in the originalSpider - Mantrilogy .

Replacement: Diane Keaton

Since it would be both unlikely and bad to fetch the original Aunt May actress Rosemary Harris back to the character of Aunt May , there may be another choice .

Academy Award winner Diane Keaton would be the perfect convulsion for the office of Aunt May in future tense   Spider - Man movies .

Not only does Keaton have the perfect appearance and age for Aunt May , but she also has some incredibly impressive acting chops that would be just as good as , if not better than , Rosemary Harris ’s performance as May Parker from the other 2000s .
