THR was also in attendance and wrote the following in regards to what they saw:
It began with Falcon and Black Widow (Scarlett Johansson), working with Captain America to take down Crossbones (Frank Grillo) in a crowded urban environment. “You know, he remembered you. Your pal, your buddy, your Bucky,” says Crossbones to a confused Cap. It then cuts to a speech from General Thunderbolt Ross (William Hurt), who lectures Cap in Avengers headquarters.
“The world owes you an unpayable debt. A lot great many people see you as a hero,” says Ross. “There are some who prefer the word vigilante. People are afraid.”
The biggest applause came from this line from Iron Man (Robert Downey Jr.) to Captain America, who are arguing about the ethics of being a superhero: “Sometimes I want to punch you in your perfect teeth.” It also appears Winter Soldier (Sebastian Stan) is a good guy in the film, which deals with the downside of being a superhero. “In this job, we try to save as many as we can. Sometimes that doesn’t’ mean everybody,” said Captain America.
The footage also featured Black Widow fighting her old pal Hawkeye (Jeremy Renner) and glimpse of Black Panther (Chadwick Boseman) as well as a funny scene with Ant-Man (Paul Rudd) gushing over Captain America, who has recruited him to be on his team.
Finally, IGN had this to say about the trailer:
The footage opens with Captain America, Black Widow, and Falcon dealing with Crossbones as the villain attempts to blow up a truck. During the fight, Crossbones tosses a magnetic explosive at Cap’s shield, and the hero throws it into the air so that the explosion avoids the crowd.
So footage opens with Cap, Widow and Falcon stopping a truck bomb and then battling Crossbones and his goons in the streets. A magnetic explosive is tossed on Cap’s shield who then throws it into the air so it explodes away from crowd.
Crossbones removes his mask and reveals his scarred face, turning to Cap and saying, “He remembered you, you know. You’re little pal Bucky.” The footage then cut to the scene during the credits of Ant Man, where Cap and Falcon are talking to Bucky. Bucky tells Cap that he remembers his mom’s name was Sarah, and that he used to stuff newspapers in his shows. Cap smiles, knowing that some trace of his old friend is still in there.
We then see General Ross (William Hurt, reprising his role from Edward Norton’s Incredible Hulk) telling Cap how the country owes him an impossible debt, but that for some he’s not a hero now but a vigilante. Cut to shots of Cap and Tony talking about what comes next, that Tony says how they’re operating with oversight so how does that make them different from villains? “That’s what this is about to you? Protection?” says Cap. While continuing to argue, Iron Man tells Cap, “Sometimes I want to punch you in your perfect teeth.”
The footage then rolls into quick shots of the heroes delivering some pretty great lines. “In this job, you try to save everybody you can. Sometimes that doesn’t mean everybody,” say a stoic Captain America.
Black Widow and Hawkeye, caught on opposite sides of the Civil War, are about to fight. “We’re still friends right?” Black Widow asks. “Depends on how hard you hit me,” Hawkeye replies.
The footage ended with Hawkeye opening a van, revealing Paul Rudd’s Ant Man. He’s absolutely starstruck by Captain America. He’s shaking as he meets him, and fumbles the greeting. “You know a lot of super people, so thinks for thanking of me.”
Turns out that leaked trailer description wasn’t accurate then, but it still looks like we’re in for a wild ride here. Deadline went onto describe the footage as “awesome,” while Variety called it “bananas.” More reports on the trailer can be found at The Wrap, Mashable, CBR and JoBlo, so be sure to check those out as well and let us know what you think.
