Robert Downy Jr. had been playing the character of Tony Stark for more than ten years when shooting “Avengers: Infinity War.” Thus, the filmmakers usually just let him have free reign of his quips and one-liners. After Iron Man fights Ebony Maw with Peter Parker and Doctor Strange, Peter Parker says that he’s back up.
Stark quickly tells him that the adults are talking, and the little bit of humor it brought was unscripted. It was all RDJ. Of course, Iron Man soon after dubs Spider-Man to be a full member of the Avengers. We’re not sure if that was in the script. Doesn’t matter!
It Was Inevitable
In a scene that will go down in movie history for what may be centuries, after Thanos delivers his line of “I am inevitable,” Iron Man responds with a reprise of the very first MCU movie: “And I...am...Iron Man.” It sent chills through everybody watching, but it originally wasn't in the script.
During editing, the scene felt lackluster, with the Russo brothers trying a number of things to punch it up. Editor Jeff Ford suggested going back to Iron Man's beginning, and the team scrambled to get cameras set up and call Robert Downey Jr. It looks seamless, and it will echo in cinematic history.
The Chants From Black Panther Return
“Black Panther” and “Avengers: Infinity War” were being shot at the same time, so when it came to the huge battle outside Wakanda at the end of the latter, the Russo brothers got a surprise. Winston Duke, who plays M'Baku, randomly led a war chant that had first appeared in “Black Panther.”
It led to the equally-unscripted moment of T'Challa roaring out the very real word “Yibambe” to his army. It was the perfect way to bring the fun culture of Wakanda into this huge movie in an impactful, immediate way.
Who Are You?
There had been superhero movies before it, but 1989's “Batman” changed the game. It grossed over four hundred million dollars worldwide and started a trend that now dominates the box office.
When Michael Keaton dangles a goon off a roof, he's asked “Who are you?” While the script called for Keaton to respond with “I am the night,” he decided to trim it a bit, and he instead responded with “I'm Batman.” It was snappier, punchier, and so much more memorable.
Anthony Hopkins's Incredible Snarl
The emotions that flow during one of the most emotional scenes of the first Thor movie are well-known, since giving a legendary actor like Anthony Hopkins free reign makes good things happen. His noteworthy performance brought Tom Hiddleston and Chris Hemsworth to tears, but one element of the scene was totally improvised – the fierce snarl Odin delivers to shut the “brothers” up.
The shock on Tom Hiddleston's face is entirely genuine. It also feels very much like what a father, fed up with his sons, would do – he'd respond to their pointless arguing with wordless rage. Maybe Hopkins knew this, or maybe he just voiced the character's disappointment in the way that worked the best.
