Thanks to an expanded collection of hidden backstage cameras, which capture unscripted action near the green room, the lobby, the winners' walk and the Governors Ball, fans can click around on Oscar.com to see various perspectives that aren't part of the main telecast.

"We want to encourage them to be part of the experience," said Christina Kounelias, chief marketing officer for the Academy of Motion Picture Arts and Sciences.

"We're giving fans the control to follow their favourites," added Karin Gilford of ABC's digital media division.

The Oscar.com site will have more than a dozen cameras filming the proceedings on the red carpet, backstage and inside the theatre, where a camera will be trained on front-row celebrity minglers during commercials.

The celebrity surveillance, which is free, will begin with the start of red carpet arrivals and continue with live feeds until the Governors Ball gets under way.

There are no hidden cameras in the theatre's restrooms.
