Behind-The-Scenes Facts From The Avengers Movies That Demand A Rewatch

List Rules
Vote up the facts that made you say, 'Whoa.'

The Marvel Cinematic Universe began in 2008 with Iron Man, and for the next few years, it seemed as if Marvel Studios was trying things out to see what worked. Gradually, the studio built up enough characters for a movie featuring all of them, and in 2012, Marvel's The Avengers hit theaters to widespread critical acclaim. The MCU proved it could be done - a single movie featuring six major stars playing incredibly important characters could work, and it made the studio a lot of money.

With the success of The Avengers, it was only a matter of time before a sequel hit theaters. Avengers: Age of Ultron came in 2015, and Avengers: Infinity War and Avengers: Endgame were released in 2018 and 2019. Combined, the movies absolutely destroyed box-office records, and they helped make the MCU into the most successful film franchise of all time. All four Avengers films have been scrutinized by the fans, but there's always something new to learn about Earth's Mightiest Heroes and some of the impressive battle scenes they've been in over the years.

That's especially true when you're looking at some of the things that happened behind the scenes. The Avengers movies certainly had a lot going on that wasn't revealed until much later, and when you find out what those things were, you're going to want to go back and rewatch them all. This list compiles some of the most fascinating behind-the-scenes facts from the Avengers movies that'll make you want to sit through them all over again! Take a look down below, and don't forget to upvote your favorites before you head back to the couch to chill with Earth's Mightiest Heroes for a few hours.

    Tom Holland Improvised A Famous Line

    When characters begin to fade into ash at the end of Avengers: Infinity War, the realization that the heroes have failed can't be more apparent. It happens quickly, and in most cases, it's not incredibly dramatic. Then, Spider-Man begins to fade away, and the drama is ramped up to 11. The scene is heart-wrenching for several reasons, and they're all pretty sad. Because of his Spider-Sense (Peter Tingle), he feels himself beginning to fade away, which is why he reaches out to Tony Stark (the man he thinks of as a father).

    He says to him, "I don't want to go," and then he does, leaving Tony to deal with the aftermath and loss. That last bit of dialogue wasn't in the script. It was improvised by Holland, and they shot several takes before settling on the one that made it into the movie. It's one of those lines that seems as if it should have been in the script all along, but it was all Holland's idea. Holland discussed the scene, which was his favorite, in an interview with Deadline:

    "I don't want to go" is the one I get all the time from that scene in Avengers: Infinity War. It's amazing when people think it's some mind-blowing piece of improv because I just say the same line five times in a row. People make out like it's this beautifully eloquent sentence. But I look back on that scene so fondly. We had so much fun on those sets, but when we got into the emotion of that moment, we really dived into it. People tell me they imagine that scene must have been horrendous to shoot, but I look back on it with nothing but happiness. It was amazing. I loved it. I got to hug Robert Downey Jr., like, 60 times, and cry on his shoulder. What's not to love?

    Peter's Spider-Sense In 'Infinity War' Isn't The Product Of CGI

    One of Peter Parker's most useful superpowers is his Spidey-Sense, which warns him of imminent danger. This is typically indicated by lightning bolts shooting away from his head in the comics, but that's not something that translates well in live action. At the beginning of Infinity War, Peter and his classmates are traveling on a school bus when Peter's Spider-Sense starts tingling, and this is indicated by having his arm hair stand straight up.

    You would be forgiven for thinking that this was accomplished via CGI, but it wasn't. This was the first time this particular power was shown on-screen, but getting Tom Holland's arm hair to raise like that was achieved practically. Nobody was on-hand with a plasma globe or anything like it to achieve the effect; instead, someone was just off-camera blowing into the actor's ear. Sometimes, the easiest solutions work the best. Directors Joe and Anthony Russo explained how they made it happen:

    Joe Russo: We get asked this all the time. How did we get the hair on Tom Holland's arm to stand up?

    Anthony Russo: In our New York Times "Anatomy of This Scene," we finally revealed... a lot of people think it's a CG shot, but it was actually achieved by a very gentle blowing on Tom's ear.

    Black Widow Wasn't Supposed To Be Interrogated At The Beginning Of 'The Avengers'

    One of the best scenes in The Avengers features Scarlet Johansson's Black Widow being interrogated by some lowlife thugs. The scene unfolds with her receiving a phone call from Agent Phil Coulson, calling her in from the field. She then proceeds to beat the snot out of every one of the bad guys while being tied to a chair, and it's the perfect introduction for her character in the film.

    As it happens, that scene was originally much different in the script. According to Zak Penn, who wrote one of the drafts of The Avengers, the original concept saw Hawkeye being interrogated instead of Black Widow. Director Joss Whedon was the one who came onto the project and changed the scene (and many others), and it would be difficult to find many fans of the film who thought he made the wrong move. While an interrogation scene with Hawkeye would likely have worked, it's hard to imagine anyone but Black Widow carrying this scene.

    Captain Marvel Vs. Thanos Was A Last-Minute Rewrite

    When it comes to fight scenes, Avengers: Endgame has a lot of them. It has fights between hundreds of characters, as well as several that are one-on-one. Captain America's fight against Thanos is the stuff of cinematic legend, and while it's undoubtedly impressive, it's not the only fight that makes Thanos rethink his battle strategy. The bout between him and Captain Marvel was exceptionally well-done, and the fans loved it.

    Captain Marvel comes out of nowhere to stop Thanos from putting on the Infinity Gauntlet and snapping his fingers, and she nearly beats him. He punches her in the face, but he doesn't even make her hair move, so he pulls the Power Stone off the Gauntlet and lets her have it. It's a great scene, and it shows how the fight is balanced, even with a powerful player like Carol Danvers in the battle. While it's a beloved scene, it wasn't originally in the script.

    In an interview with /Film, film editor Jeff Ford explained how the battle made it into the movie. "When Captain Marvel arrives, that was in the script from day one, the way she comes through the ship," he revealed. "We knew she was going to do that, but what we did alter and add and expand later, mostly because of how much we loved what Brie [Larson] was doing with the character, was her fight with Thanos before he power punches her back."

    Ford explained how things changed when they got into making the movie: 

    Anthony [Russo] came up with the great idea - this was a reshoot, by the way, at the last minute - he had the great idea that Thanos pulls the power stone out of the Gauntlet, and then he punches her with the raw power stone. That is a fantastic use of that prop and that story point because that's what you want. And we had to find a way that he could sideline Captain Marvel for a minute because she's so powerful, there's no way to do it.

    Actors Had To Work Opposite A Floating Thanos Head And Shoulders In 'Infinity War' And 'Endgame'

    In the old days, actors would get onto a stage or set and act opposite one another. This was how it worked for thousands of years, but things had to change when CGI came along to dominate the industry. No longer would an actor play off the reactions of another when all they had to look at was a ping pong ball on a stick! Changes like that can be difficult for any actor to become accustomed to regardless of how long they've worked in the industry.

    When it came time to create Thanos for Avengers: Infinity War, the VFX department had to develop a way to properly represent the character. Thanos stands about 8 feet 3 inches tall in the MCU, and Josh Brolin couldn't exactly act that tall. Brolin is only 5 feet 10 inches, so to portray the Mad Titan, he wore a ton of motion-capture gear and a giant foam head and shoulders that was situated just above his head. This gave the other actors a point of reference to look at while they were acting, but it must have been hilarious because pictures of Brolin in the getup are pretty silly-looking.

    A similar method was used for Ultron in Avengers: Age of Ultron, and many of the actors who were in scenes with the character had trouble focusing on the right thing. It's more natural to look at the actual person instead of looking a few feet above their head. It took some work (and a lot of takes), but everyone managed to look in the right places when push came to shove.

    Robert Downey Jr. Hid Food On 'The Avengers' Set

    While you'd think that someone appearing in a superhero movie would be concerned about adding any unnecessary calories, Robert Downey Jr. doesn't share those concerns. While filming The Avengers, he hid food all over the set - which, it turns out, is not uncommon for RDJ. In a live interview with HuffPost for the movie The Judge, his castmates claim he continues the practice outside the MCU.

    In the interview, Vincent D'Onofrio spoke about it, saying, "Downey does hide food all over [the] set." He added, "I'm not going to tell you why. But he does. It makes perfect sense."

    He's apparently well-known for doing this while he's working, and it's said that his directors don't mind because it often adds some comic relief to the long hours of filming. In some scenes in The Avengers when he's eating food, it's from his own stash. For example, in one scene he's eating blueberries, and even offers one to Cap. Those blueberries were from his stash, and the line wasn't in the script... it was just RDJ being RDJ.
