Still, a few interesting behind-the-scenes secrets of the Marvel movies keep tumbling out into the open now and then. Some are shocking yet hilarious, and we cannot help but share them with you.

What’s real is the training each of the heroes and supervillains undergoes to make the scenes look realistic. Jeremy Renner, who played Hawkeye, an ambidextrous archer, was trained by none other than Olympic archers!

Who can forget the smash-ing moment from Thor: Ragnarok in which Hulk turns him into a ragdoll and mercilessly wallops him to the ground? Credit to Tom Hiddleston for pulling off a Hulk-induced traumatized look later, thanks to the director violently shaking him before the shot.

As a spontaneous actor, Robert added clever ad-libs to his performance in the Marvel movies. Thanks to his shawarma line in one, shawarma sales in the U.S. skyrocketed after the movie’s release. His speech about not coming in tomorrow was a memorable addition.

Indeed, Quicksilver had to have less muscle mass to justify his speed. So, Aaron complied and gave us a leaner and meaner superhero in the 2015 movie.

To prepare for the character of meta-human Wanda Maximoff, Elizabeth trained under a dance choreographer, and we can see it pay off; she glided through her fight scenes and stole our hearts.

Though each of these actors fit perfectly into their roles, Iron Man stands out in some ways. In many cases, he is known to pull off his own stunts, amazing viewers and directors alike. That’s not all. The actor’s martial art skills come in handy when he needs to fight his way through notorious enemies like Thanos. Perhaps, that was how the lingering Civil War ended.

Therefore, to help us appreciate the person of Captain America, the cameras had to do their tricks. They made the actor look a few inches taller than Bucky Barnes when, in fact, the two actors are about the same height. So, combining the Captain’s huge shield and amazing cheekbones, the actor looks nothing less than our ideal hero.

Tilda runs her own team of highly talented workers and brings them along to make her projects all the more memorable. Surprisingly, just like Mark Hamill in Star Wars, Swinton’s team also includes her illustrious kids. They are fully involved in making the costumes, and their involvement most likely helps Marvel cut down production costs. We won’t be surprised if this wonderful family decides to roll out their own film someday.

While his eyes have always looked that way, the actor maintained a strict diet before production to ensure that he either lost some pounds or didn’t gain any extra. In the end, he looked every bit like the legendary Thor and the supervillain we all need to be rescued from.

Michael B. Jordan, one of the lead actors in Wakanda, is a good example of this. Before and during production, he spent lots of his time away from others so he could feel and think like his character: a distant fellow in conflict with others. Not everyone can stomach this.

Due to Portman’s schedule, Hemsworth decided to shoot the last scene with his wife, Elsa Pataky. All she had to do was wear a wig and kiss her husband.

That’s right! Though Cara Danvers is indestructible, a little cat hair might just lead to her downfall. Actress Brie Larson has chronic cat allergies and had to shoot her scenes with a realistic cat puppet.

Captain Marvel was the first film released after his demise and the last one to pay tribute to him. It featured an epic logo redesign and footage from his past appearances, along with a special thank-you note to their late founder.

Groot’s lines were shot in Brazilian Portuguese, Spanish, Mandarin Chinese, French, and even Russian! It’s great to know that Marvel Studios is open to diversity.

He hated wearing a wig for the first Thor movie, so he grew his hair out for the second one in just a year! If Hemsworth ever decides to publish a book on hair growth, it would certainly be a bestseller.

In the case of Paul Rudd, he learned the necessary magic skills for his role in Ant-Man and the Wasp. We applaud his efforts because learning magic is not something that can be done overnight.

It turns out actors are not left out when it comes to this rule. Scarlett Johansson showed up as a redhead to the auditions for Iron Man 2. With such commitment and confidence, she was sure to land the role, and she did!

For Mickey Rourke, he revealed that the hardest part about playing the tech genius Whiplash was pretending to know how to effortlessly use a computer.

Take, for instance, Ever Anderson who was already proficient in taekwondo and Russian when she landed the role of Natasha Romanoff. Hence, she could easily get into the character.

Nevertheless, leaks are inevitable sometimes. That’s when studios get creative and do everything possible with their scripts to keep the surprises intact. So, the next time you get wind of a big reveal, enjoy the secrecy and feel like a million bucks.

Every opportunity is a chance to grow, whether it’s adopting a new accent or jumping right into a difficult role. So don’t be afraid to take a risk and step out of your comfort zone – who knows? You may discover your next passion.

Despite this, it’s still entertaining to speculate about what might have been; for example, what if Wolverine, Magneto, and Captain America appeared on screen together? It would be a jaw-dropping performance recital.

Hogan may not have superpowers, but he’s still a vital part of the team (on top of having great taste in TV series). Next time you watch a Marvel movie, pay attention to the supporting cast; they may be the real surprise package.

Still, did you know that his name is actually an acronym? Just A Rather Very Intelligent System. As hard as it is to guess, it’s classic Tony Stark humor, which makes the character even more endearing. Here’s hoping we see more of J.A.R.V.I.S in the future.

Tom Holland later confirmed that the beloved teen from the Back to the Future franchise indeed inspired his character. The movie also pays tribute to John Hughes’ classic comedy Ferris Bueller’s Day Off, making it a fitting coming-of-age superhero flick.

It’s not surprising that Marvel creators were huge fans of Jackson and based the character of Captain Nick Fury on him. As a special nod to the actor, Fury’s tombstone even references Jules’ famous Bible verse from Pulp Fiction.

It, however, looks like the makers already knew Groot would become everyone’s favorite as a seed was saved, and a tiny tree monster was planted. While the prequel had a glimpse of a dancing baby Groot, the sequel had an entire dance sequence which apparently took two years to complete!

Luckily, screenwriter Nicole Perlman confirmed with the U.S. Air Force that someone of Larson’s age could become a pilot at Carol Danvers’ level. It was the reassurance they needed to cast Larson in the role and make Captain Marvel a reality.

The creators decided to retain this unscripted moment, as it fit right into Thor’s character. After all, who else could make smashing things look like muscle memory? Moreover, never underestimate the power of a good cup of coffee.
