The Empire Podcast with Joss Whedon is filled with Avengers: Age of Ultron goodies. One of them, is when Whedon discusses the moment in the film where Thor distrust for The Vision dissolves in a blink of an eye. Whedon explains how the scene developed, saying, “That came from a ‘Do you know what would be cool?’ moment. It’s the cheer moment of the film. And what’s great is that, like the Hawkeye thing, we’d set it up – we’d unknowingly set it up, just by having that sequence, then with Quicksilver as well, trying to grab it and it throws him off.”
