This might be unpopular but

Who ever plays her obviously should be a great actress singer watever

But they cant be famous, cuz idk britney is a legend and if the person that plays her is famous itll be hard for me to imagine that as britney spears cuz itll be like millie bobby brown not britney spears idk how to explain it

But biopic's work best when the actor isnt famous like in Priscilla or elvis

If Priscilla was played by lana del rey, it would be hard for me to imagine Priscilla because id be like "omg thsts lana del rey"

Idk
