LOS ANGELES: Variety has obtained exclusive photos of PricewaterhouseCoopers accountant Brian Cullinan -- the man behind the infamous envelope mix-up -- leading up to and during Sunday's gaffe in which "La La Land" was erroneously named best picture over "Moonlight."
PWC has already confirmed Cullinan, a top executive at the firm, as the person responsible for giving presenter Warren Beatty the incorrect envelope.
