Former Academy Awards host Neil Patrick Harris noticed the Oscars best picture snafu as it happened

Warren Beatty seems to be opening an envelope that says 'Actress in a Leading Role'. He must have been handed the wrong one somehow. Yikes. pic.twitter.com/Rma4wp80aX

What the what what?? What just happened?!? How did Emma Stone's name get in a second envelope? Weirdest. Ending. Ever.

I feel bad for all involved: Warren, Jimmy, Marc Platt and the incredible La La Land team. That said, congrats to Moonlight. It's brilliant.
