The 89th Annual Academy Awards were held last night at the Dolby Theater in Los Angeles with Jimmy Kimmel as the host.  Adding a bit of excitement to the night was the mix-up that took place, where Warren Beatty announced the wrong film for Best Picture. Pricewaterhouse Coopers issued a statement about the incident as follows:

We sincerely apologize to "Moonlight," "La La Land," Warren Beatty, Faye Dunaway, and Oscar viewers for the error that was made during the award announcement for Best Picture. The presenters had mistakenly been given the wrong category envelope and when discovered, was immediately corrected. We are currently investigating how this could have happened, and deeply regret that this occurred.

We appreciate the grace with which the nominees, the Academy, ABC, and Jimmy Kimmel handled the situation.
