While much is still unknown about Avengers: Infinity War, early indications are that it will be a cinematic event unlike no other. With the film boasting a growing slate of characters from across the Marvel Cinematic Universe, bringing together a cast of that size would seem like a daunting task.

But according to Kevin Feige, president of Marvel Studios, the combination of so many of the MCU's stars has created some surprising - and ultimately gratifying - reactions on set.

"There is nothing more fun about seeing superstars who carry their own franchises – and essentially have seen it all and done it all – coming onto a set and meeting other actors and A-listers and iconic characters in costumes, and seeing them get giddy." Feige explained in a recent interview with Fandango. "Seeing them turn into kids because of how excited they are on set. That is happening every day right now."

According to Feige, that camaraderie between Infinity War's cast is going to have more and more room to grow, as the film's production is set to stretch for many more months.

"We're deep into shooting." Feige revealed. "We've been shooting for 35 days. On most movies you're almost halfway there after 35 days, but on these movies we're still just scratching the surface. We'll be filming through the end of the year."

Avengers: Infinity War is described by Marvel Studios as the culmination of everything in the Marvel Cinematic Universe since Iron Man in 2008. The movie is filming now under directors Anthony and Joe Russo, from a screenplay by Christopher Markus and Stephen McFeely.

The expansive confirmed cast includes Robert Downey, Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Tom Holland, Elizabeth Olsen, Paul Bethany, Sebastian Stan, Benedict Cumberbatch, Benedict Wong, Chris Pratt, Zoe Saldana, Karen Gillan, Vin Diesel, Dave Bautista, Bradley Cooper, Pom Klementieff, and Josh Brolin as the villain Thanos. Avengers: Infinity War and its as-yet-untitled sequel are filming for a May 4, 2018 and May 3, 2019 release, respectively.
