Marvel’s casting director has revealed interesting details about how the studio found the Avengers. While 2008’s Iron Man was a huge success, it was not until 2012’s The Avengers that the Marvel Cinematic Universe really exploded in terms of popularity. Fans loved the interaction between the different heroes on the team, which led to all four of the MCU’s Avengers movies so far making at least $1 billion at the box office. Now that Marvel is bringing back most of the original Avengers cast for the team’s next two films, insight into how the actors were chosen has been shared.

Speaking on The Official Marvel Podcast, Marvel Studios’ casting director, Sarah Halley Finn, revealed the secret to casting the MCU’s Avengers. According to her, it all came down to individual stories. Finn says Marvel’s thought process was focused on finding the best possible actor for each hero and building a supporting cast that would complement them, not thinking about crossovers with other heroes. When casting a less experienced actor like Chris Hemsworth was at the time, Marvel would balance that with names like Anthony Hopkins as Odin. In the end, the Avengers’ chemistry was “able to happen magically,” leading to some of the MCU’s best movies. Check out the full quote below:

Sarah Halley Finn: “Honestly it’s a little bit hard for me to talk about it from an outside perspective, because I’m so very close to it – but what I really remember when we were casting it is that our focus was very singular. It really was entirely about ‘who is the best person to bring this character to life?’ And then when we’ve got the main character, how do we best surround them, you know?

So when you have somebody that’s newer on the scene like a Chris Hemsworth, can we get an Anthony Hopkins? Could we get – like, how do we then build the ensemble if it’s Chris Pratt and he’s know more for comedy? What if we bring in Zoe, who we know is gonna up the ante for him and then make it challenging?

But you know, with every character I was always casting one movie at a time, so I was never really casting The Avengers, that all was able to happen magically, and I do think it’s a testament to the caliber of actors, to the writing, to the directing, to the vision that Kevin had throughout – and really also probably benefitted from the time we had to live with these characters and get to know them, and the stories that were being told, and the way they all were growing with us. But when they did first come together in The Avengers, the reaction to that film was electrifying, I think for all of us, and honestly humbling.”

What Sarah Halley Finn’s MCU Casting Comments Mean

Marvel Had A Clear Vision For The Franchise

Sarah Halley Finn’s comments are interesting. They reaffirm the commitment the MCU had to slowly develop its heroes before they came together. While Marvel Studios President Kevin Feige always planned for The Avengers to happen, the most important thing for Marvel was getting the individual heroes right. After all, if fans did not care for the characters separately, it would be hard for them to really be excited when they came together. Finn’s comments are also insightful in the way that they reveal how Marvel cast projects around its stars’ needs.

So, with Chris Hemsworth, who was a soap opera star, Marvel got Anthony Hopkins as Thor’s father, bringing in a Hollywood legend to challenge Hemsworth. Likewise, in Chris Pratt’s case, the Guardians of the Galaxy star was well-versed in comedy, so Zoë Saldaña was chosen as Gamora, bringing in a proven actress in drama to balance Pratt’s Star-Lord as his love interest. Those choices helped create well-rounded heroes and projects right from the start of the MCU. As such, Finn’s comments help illustrate just how crucial her work is to the franchise’s success if someone still did not realize it.

Our Take On Sarah Halley Finn’s MCU Casting Comments

Marvel Studios Always Knew What It Had To Do To Succeed

I think Sarah Halley Finn’s comments are great, showing what Marvel Studios deemed was important when casting the original Avengers and other early MCU heroes. The franchise has thrived because of that careful planning, and rushing the crossover between the MCU’s heroes would not have made it any better, as the old DCEU exemplified through its handling of the Justice League. As such, I’m glad that Finn continues to work at Marvel after all these years, and with most of the original Avengers cast back in the MCU, the franchise’s next few projects should be very exciting.
