Who is presenting at the Oscars?

Fans probably know that Chris Rock will host the 2016 Oscars and that Lady Gaga, The Weeknd, and Sam Smith, all of whom are nominated for Best Original song, will each perform at Sunday night’s Oscars ceremony. The only questions that remain are who’s presenting, and who will win?

We can’t help you with the second question (though we’ve made our predictions), but we’ve got answers for the first one. The Academy has made four rounds of presenter announcements thus far, and while there might be some additional surprise appearances this weekend, we know for sure that certain famous faces will take the stage.

Last year’s acting winners were all listed among the presenters, so we can safely assume that, as in years past, the most recent Best Actor and Actress Eddie Redmayne and Julianne Moore will present each other’s categories, and the reigning Best Supporting Actor and Actress J.K. Simmons and Patricia Arquette will also present to the opposite winner.

Olivia Munn and Jason Segel hosted the Sci-Tech Awards on Feb. 13 and will be back for the main telecast as well. In a list that includes both past winners and current nominees, the rest of the announced presenters are:
