Fan Casting Janet van Dyne in Edgar Wright's Astonishing Ant-Man

Janet van Dyne was the youngest child and only daughter Vernon van Dyne, CEO of Dynatechnics, a materials processing corporation based out of Chicago but with plants and offices across the Rust Belt. Because of her father's insistence that only her brothers enter the family business, Janet found herself growing increasingly bored with the role of a high society socialite. It was at a party that she'd been invited to where she met Dr. Henry Pym, a scientist who worked at Dynatechnics. It wasn't long before the two began dating. Janet possessed a sharper mind than she let on, and quickly discovered that Pym was the adventurer Ant-Man. Janet asked him to help her gain powers of her own so that she could aid him. Hank resisted at first, but Janet's youthful enthusiasm and subtle half-joking hints of blackmail convinced him. Sneaking her into the laboratory one night, he performed surgery on her which grafted wasp-like wings to her back and boosted her natural bioelectricity to enable her to fire short-ranged electric bolts from her hands. He then gave her a supply of the Pym particles for her to use. Designing an outfit for herself and calling herself the Wasp, she became Ant-Man's partner. As the Wasp, Janet was present at the first meeting of the Avengers, and suggested the team name. She has managed to keep her identity as the Wasp secret by not allowing herself to be photographed at her full height; unlike the others, however, she doesn't really care if her identity as the Wasp is revealed.
