Today’s newest set of presenter announcements bring the total to 24. I’ll also add the two other “presenters” announced this weekend, namely the hosts of this year’s sci-tech awards: Olivia Munn and Jason Segel (who are included in both press releases below.

We’re still missing performers for two of the nominated songs, “Simple Song #3,” which might not get a well-known name attached (at least outside of operatic circles) and “Manta Ray,” which most certainly should have its nominated singer/songwriter perform…even though that hasn’t been announced yet.

The only other tradition that is so far incomplete is the prior year’s acting winners returning to present. We have two of the four slated below, Julianne Moore and J.K. Simmons. I’m assuming that both Eddie Redmayne and Patricia Arquette will be in a future press release.
