Every Upcoming Marvel Movie: Full MCU Phase 6 List (& Beyond)
With Marvel Studios' MCU now dominating the upcoming release slate for Marvel movies, here’s what to expect in the coming years and beyond.
10"No matter what lies Erskine told you, you see, I was his greatest success!"
Red Skull - Captain America: The First Avenger (2011)
Dr. Abraham Erksine was responsible for creating Captain America. He was also responsible for creating Red Skull, a distorted mirror to the resilient Steve Rogers.When Johann Schmidt pulled off his human mask and revealed himself as Red Skull to Captain America, it highlighted the stark differences between the two characters despite both taking a form of the super soldier serum.
Red Skull is the leader of HYDRA and his arrogance shines through in this scene, which directly opposes the goodness Steve Rogers embodies as Captain America. When the villains states, “You see, I was his greatest success!” it becomes especially clear that Red Skull doesn’t see himself as a monster - instead he sees himself as the hero, the greatest success in the history of humanity up to that point.

Captain America: The First Avenger
Cast
Captain America: The First Avenger follows Steve Rogers, a frail man from Brooklyn transformed into the super-soldier Captain America during World War II. As he aids the war effort, Rogers confronts Red Skull, who seeks world domination through a powerful device for a nefarious organization.
9"Who The Hell Is Bucky?"
Bucky / Winter Soldier - Captain America: The Winter Soldier (2014)
In a tense highway fight scene that ranks among the best action set pieces the MCU has to offer, it is finally revealed that the Winter Soldier is Steve Roger’s best friend Bucky, who presumably died at the end ofCaptain America: The First Avenger. Stunned at the revelation, Captain America can only utter “Bucky?” before the Winter Soldier retorts with, “Who’s Bucky?” This moment underlines just how alienated from himself Barnes has become, cementing the tragedy of his time as an MCU antagonist.
At this point inCaptain America: The Winter Soldier, the titular villain was a mystery to Steve Rogers. The Winter Soldier being revealed as Bucky showed that their conflict would test Steve’s resolve as a human even more than his physical prowess.In that moment, it was clear the rabbit hole went farther than Captain America thought it did, altering what he thought he knew moving forward.

8"But While A Great Many People See You As Heroes, There Are Some Who Would Prefer The Word ‘Vigilantes’."
Thaddeus Ross - Captain America: Civil War (2016)
Thaddeus Ross returns inCaptain America: Civil Warin an attempt to get the Avengers to sign the Sokovia Accords as a direct result of their actions inAvengers: Age of Ultron. Thaddeus iterates that many “would prefer the word ‘vigilantes’” when discussing how the team operates and how they go about completing missions. The quote boils down the Avengers to their simplest terms while highlighting the repercussions of their actions so far.
In this moment, it seems that Thaddeus Ross also views the Avengers in the same light.This scene is the driving force behind the entire film and the point where the conflict between Tony Stark and Steve Rogers begins to root itself into other members of the Avengers.Up until now, most of the Avengers have seen themselves as the heroes of the story, but being called vigilantes and needing to sign the Sokovia Accords dictating how they will operate going forward is one of the biggest moments in the MCU.

Captain America: Civil War
Captain America: Civil War focuses on the aftermath of Age of Ultron as international governments legislate to regulate superhuman activity. This divides the Avengers, forming opposing factions led by Iron Man and Captain America, culminating in a significant conflict between former allies.
7"I Have Seen The Future, Captain! There Are No Flags!"
ThroughoutCaptain America: The First Avenger, Steve Rogers has been proudly donning the red, white, and blue of America as he works with the military to help end the war and stop the Nazis. To Steve Rogers, the war is a battle of nations, but to Red Skull, nations will cease to exist under the rule of HYDRA.While once again trying to show Steve Rogers his way, Red Skull highlights one of their biggest differences: “There are no flags!”
In a future where Red Skull is successful and HYDRA becomes the dominant power, the stars and stripes Captain America dons won’t matter anymore. Steve Rogers fights for his country and what he believes is right, while Red Skull wants those countries to become obsolete and powerless before ceasing to exist. As such, Red Skull craving the power to shape the future the way he sees fit comes through especially well in this line.

6"HYDRA Created A World So Chaotic That Humanity Is Finally Ready To Sacrifice Its Freedom To Gain Its Security."
Dr. Arnim Zola - Captain America: The Winter Soldier (2014)
When Steve Rogers and Natasha Romanoff become fugitives and go on the run, they encounter the consciousness of Dr Arnim Zola, who explains that HYDRA has continued to operate despite Red Skull dying at the end ofCaptain America: The First Avenger. He recounts the motivations of HYDRA throughout their history, how they infiltrated SHIELD, and the chaos they have created throughout humanity post World War II. The very organization Captain America was working for was compromised the entire time.
Zola claims that humanity will “sacrifice its freedom to gain its security” and allows Rogers a look behind the veil that SHIELD had turned into.Everything that Steve believed in has begun to come crumbling down, and the final steps of HYDRA’s plans are being put into place. The moment proves especially harrowing for the hero, as if humanity is truly ready to sacrifice their freedom for more peace of mind, then HYDRA has won and everything Rogers and Romanoff have been fighting for will be for nothing.
5"And The Dust Cleared… And The Screaming Stopped… It Took Me Two Days Until I Found Their Bodies."
Zemo - Captain America: Civil War (2016)
Zemo and Black Panther finally coming face to face as Iron Man and Captain America fight each other below is one of the most poignant moments in the MCU. During their confrontation, Zemo reveals that he believes the Avengers were responsible for the death of his family during their fight against Ultron in Sokovia. “It took me two days until I found there bodies,” Zemo recalls, looking off into the distance.
Captain America: Civil Wargrapples a lot with what happened in Sokovia, and this moment where Zemo reveals his motivation for attempting to dismantle the Avengers brings it altogether.It instantly humanizes Zemo and helps the audience understand his motivations, while also allowing Black Panther to step back and see where his own thirst for vengeance was leading to.Civil War’s themes are perhaps on best display here, and the moment remains a core part of the overall MCU mythos deservedly to this day.
Black Widow Secretly Explained Why Zemo Never Attacked The Red Room
The Red Room’s Black Widow agents are similar to super-soldiers, but they never made Zemo’s agenda—and Marvel’s Black Widow movie shows why.
HYDRA Agent - Captain America: The First Avenger (2011)
Following his transformation after being injected with the super soldier serum, Captain America gives chase to a HYDRA agent that had snuck in, stole the serum and killed Dr. Erksine. After the chase ends, Steve is interrogating the agent who then utters his final words, “Hail HYDRA” before taking his own life. This starts to set things into motion for Captain America, who begins to learn about HYDRA and how they are involved with the war.
This proves to be another prime example of Captain America beginning to understand that what he thinks he knows isn’t the bigger picture. The super soldier serum goes beyond just the war at hand and the introduction to HYDRA will presumably have a lasting impact on not only the war, but even further beyond that. It’s the first moment where Steve finds himself in a deeper plot than he originally believed.
3"We Knew, That Despite All Diplomacy And The Handshaking And The Rhetoric, To Build A Better World Sometimes Means Having To Tear The Old One Down."
Alexander Pierce - Captain America: The Winter Soldier (2014)
Before officially being revealed as a villain, Alexander Pierce talks with Captain America about his history with Nick Fury and what they believed in. He explains that “to build a better world sometimes means having to tear the old one down.“This way of thinking falls in line with the ideas set forth by HYDRA, and by the end of the conversation, Steve Rogers realizes that Alexander Pierce is also working for them.
When this line is spoken, the tension builds as all the pieces that Captain America has been learning about begin to fall into place. The ideals that motivate Pierce and HYDRA directly clash with Steve’s, who has shown countless times that he believes in humanity and largely in the systems that have been in place. Still, it’s through these moments that his beliefs in those systems are challenged, even though his belief in humankind remains as strong as ever - something that can potentially be seen to set the stage forCaptain America: Civil War.
2"You’re My Mission.”
The climax ofCaptain America: The Winter Soldierends with Cap and the Winter Soldier fighting on a helicarrier as Bucky tries to stop Steve Rogers and complete his mission. Barnes states, “You’re my mission,” in response to Captain America refusing to fight anymore and trying to get Bucky to understand who he is and what they mean to each other, letting the reveal of who the Winter Soldier is
come full circle as the hero commits to trying to save his friend.
This scene and quote is completely tragic, showing Steve’s strength of character and Bucky presumably beginning to grapple with who he is.Cap understands that fighting won’t necessarily bring Bucky back, but appears to register that if he can reason with him, then maybe his old friend is still in there somewhere. The moment of hesitation before Bucky says the line also indicates that it is possible that Steve could get through to him.
It’s Too Late For Bucky Barnes To Find Closure For The Winter Soldier’s Most Heartbreaking Sin
Sebastian Stan has played Bucky Barnes, the MCU’s Winter Soldier, since Captain America: The First Avenger, but his biggest sin may never be resolved.
The final confrontation between Zemo and Black Panther is full of incredible lines that stand among the best the MCU has to offer. Talking about his motivations for his actions, Zemo reveals he wanted to tear the Avengers apart and to do that he had to get them to turn on each other, comparing them to an empire. He understands that his plan succeeding will create a lasting conflict for the iconic superhero team that could be impossible to repair.
Zemo’s life was torn apart when the Avengers fought Ultron in Sokovia, and he has been planning his revenge since. Sitting in the snow, he sees his efforts come to fruition and his life seemingly coming to an end.Captain America: Civil Waris a movie about vengeance and how it can tear someone apart. With Iron Man andCaptain Americaengaging in the conflict Zemo sowed, Black Panther registers that justice and revenge are two different things because of the villain’s speech - with T’Challa and the warring heroes making the hard choice to choose the path of justice instead.
