These 25 Actors Passed on the Role of a Lifetime, but Most of Them Didn't Regret It

The role that won Emma Stone an Oscar almost went to a different Emma! Watson was initially attached to star (along with Miles Teller), but ended up having to turn it down in order to film Beauty and the Beast, which she had been committed to for years.

"I knew I had horse training, I knew I had dancing, I knew I had three months of singing ahead of me, and I knew I had to be in London to really do that," she said at a SiriusXM Town Hall event, according to Entertainment Weekly. "And this wasn't a movie I could just kind of parachute into. I knew I had to do the work, and I had to be where I had to be. So scheduling conflict-wise, it just didn't work out."
