How could this happen? This is the thinking: Price Waterhouse has two envelopes (two copies) for every winner. So when they handed the envelope to presenters they opened that for Emma Stone for Best Actress rather than the envelope for Best Picture.

This has happened before, according to our colleague Pete Hammond, back in 1964 when Sammy Davis, Jr. also got the wrong envelope for the two music categories.
