I might very properly be mistaken right here, but it surely’s doable that the footage shared by Robert Downey Jr. is from the unique model of Tony Stark’s loss of life – because the second was notably reshot when Avengers: Endgame was in post-production. It was editor Jeff Ford who got here up with the thought for the hero to answer Thanos’ “I’m inevitable” with “And I’m Iron Man,” and the scene was redone on a studio lot in Los Angeles (humorous sufficient, it was the identical location the place Downey Jr. first display screen examined for the Marvel function). What we see within the behind-the-scenes video above could also be from the scene that was filmed throughout principal images in Atlanta, however except somebody from the manufacturing confirms it we can’t actually know. It additionally might simply be that the star did a wide range of takes, together with one the place he took a peaceable beat after delivering his iconic line. Or this might simply be from an on-set rehearsal. Regardless, it is superior that we get to look at the efficiency in its rawest type.
