Black is a celebrated screenwriter.
But, he learned to collaborate when working with Robert Downey Jr.
Black revealed that shooting on Iron Man 3 would stop because Downey wanted to rewrite the scene.
---Downey would be like, ?Time!? and I?d be like, ?We?re shooting!? and he?d be, ?No, shut the cameras,? and we?d go back to the trailer and we?d all write because he wanted new lines.
