Director Damien Chazelle revealed that Watson left the project to play Belle in Beauty in the Beast. Watson recognized that with a film like Beauty and the Beast, “...It’s like you can’t half-arse a project like this, you know, you’re in or you’re out.” Apparently, Mia wasn’t the only role that ended up being recast—Miles Teller was replaced by Ryan Gosling to play Sebastian, Mia’s love interest.
