Oscars.ET was inside at rehearsals for the 95th Academy Awards Saturday, for an exclusive look at Sunday's show, which saw everyone from presenters and performers to the crew and even stand-in winners perfecting all the last minute details to ensure that everything goes smoothly on the big night.Mindy Kaling and John Cho nailed their parts after one or two tries, with the pair workshopping their jokes throughout. A discussion of whether to say «the winner is,» or «the Oscar goes to,» was had, with Kaling practicing opening the winner's envelope as well.
