Marvel Boss Kevin Feige announced that the title of Peyton Reed’s third Ant-Man is Ant-Man and The Wasp: Quantumania, but also that Big Little Lies actress Kathryn Newton was joining as Cassie Lang. She’s the daughter of Paul Rudd’s Scott Lang and she has the same powers as her father: the ability to shrink and grow in size. She did get her powers long after her first exposure to Pym Particles. She has the superhero alias Stature.
