Speaking in the December issue of SFX Magazine, Ben Affleck opened up about what Joss brought the project, speaking highly of his storytelling talent. Here’s what he said:
Joss just brought to the movie what good directors bring, which is good taste. A sense of what’s gonna work in the story and what isn’t. An instinct for realism and for finding the humanity in the characters and the humanity in the conflict, then making it accessible and relevant. I think that’s one of the things he did so well with Avengers, frankly. He really defined the tone, and it felt like a lot of the movies after that sort of fell into that tone that he created. It was a very tricky dance where you have all these people who can do all these fantastic things that’s completely absurd on the face of it, and yet, a good storyteller like Joss brings us in, makes us identify with them, makes them seem real, and makes it interesting. A lot of guys know the comic books, a lot of people have that knowledge base. What Joss really has is talent.
I wish I had the gift that he was for identifying what’s the most compelling human drama in the context of superhero conflict. But he has a very sharp mind for it. He knows exactly what he wants, almost with a surgeon’s precision. he focuses in, beat by beat, on how he’s telling the story, exactly where he’ll be editorially. What the tenor of delivery of a line should be like. He gives you comfort because you feel like he has a very clear idea of what he wants, what he expects and, most importantly, what he thinks will work.
