This is good news! Ant-Man, like the other films in the stable, are being revealed as more and more interesting as filming is underway. GotG was like that. It went from an agreed upon risky endeavor to a $94m opening due to how the timed reveal of information about the film came out. I'm not saying A-M opens to $94 but those that mocked GotG and do the same with Ant-Man might want to pull back just a bit. Plus, while Edgar Wright is a fine enough filmmaker, if this described scene was one of his sticking points then shame on him for not fully understanding the sandbox he agreed to play in. This is exactly the kind of world building stuff the fans of these movies appreciate, both general audiences and hard core comic fans. If this scene holds I'd imagine a younger recast Alexander Pierce just as they've done for Stark Sr. twice(one 30-ish, one 55+) is the route they'd go.
