While he doesn’t make the connection himself, it’s revealed that Audra, an actress, actually looks quite a lot like his boyhood crush — especially her beautiful red hair.
The reason why this would be a savvy move for IT: Chapter 2’s casting department essentially rests in Bill’s subconscious, and the nature of his relationship with Audra in Stephen King’s novel.
It’s for this reason that finding two actresses with similar appearances would be a smart move for the sequel, and should the budget and performer interest allow, it would be amazing to see those roles go to Jessica Chastain and Amy Adams.
In the book, Bill goes through his entire adult life completely forgetting about his life in Derry, Maine and the friends that he made there, but it’s clear through his significant other that he has never fully forgotten Beverly.
