The Quantum Realm Explained Before 'Ant-Man & the Wasp: Quantumania'

Ant-Man and The Wasp: Quantumania is set to kick off the Marvel Cinematic Universe’s Phase 5 and bring with it the arrival of the new big bad in Kang The Conqueror (Jonathan Majors) and yet another venture into the quantum realm. This will be the third installment of the Paul Rudd and Evangeline Lilly franchise and it will serve as the most impactful one to date, not just because of the overarching villain that will be introduced, but because of the extensive dive into the quantum realm. There have been a handful of prior MCU properties that have dipped its toe into this world, including the two prior Ant-Man movies, but none of them will use it as the backdrop to tell its story.
