Edgar Wright is directing the superhero film with Kevin Feige producing. Wright also co-wrote the script with Joe Cornish.
Plot details are still vague, but fans have suspected Wright is taking a different approach. It is unclear who Lilly would be playing, though some insiders say she would play Pym’s (Douglas) daughter and Lang’s love interest.
Pym didn’t have a daughter in the comics but Cornish and Wright could certainly have switched things up in their version by giving him one.
Marvel had no comment.
Production is set to start in April.
Lilly was most recently seen in New Line’s “The Hobbit: The Desolation of Smaug.” She is repped by Silver Lining Entertainment.
