Meet Bill Foster
Laurence Fishburne portrays Bill Foster in Ant-Man and the Wasp. Disney’s official set report introduces him as a UC Berkeley physics teacher and former colleague of Hank Pym, with professional rivalry part of their history. That background gives the scientific discussion a personal dimension before the film reveals more of his role.

Notice how Bill and Hank respond to each other’s claims and who else is affected by the problem they are discussing. Their different priorities can be followed without this introduction deciding the conflict for the viewer.
