The biggest night in film is almost upon us.
From how to watch to who's nominated, we've rounded up everything you need to know about this year's Academy Awards.

When does it air?

The Oscars will broadcast live Sunday on ABC (8 p.m. ET/5 PT) at the Dolby Theatre in Hollywood. The Oscars: All Access livestream from the red carpet and backstage will begin at 6:30 p.m. ET/3:30 PT on Oscar.com.

How can I watch?

If you have a cable subscription, you can livestream the Oscars at abc.com or the ABC app. For those watching from outside of the U.S., you can find out which network is broadcasting the event here.

Who's hosting?

Jimmy Kimmel will return for his second consecutive stint on the awards show stage.
The late-night host told USA TODAY he's ready for the return gig, so much so that he's hoping for a repeat performance of last year’s Envelopegate, in which Warren Beatty and Faye Dunaway announced the wrong film as best picture.
“I want it to happen again,” Kimmel joked, before hinting at which movie he's planning on poking fun at.
The Shape of Water is about a woman who has sex with a sea monster. So probably that one — that’s got to be right at the top."  

Who is nominated?

The Shape of Water leads with 13 nominations, including a nod for best picture. Behind it is Christopher Nolan's World War II epic Dunkirk with eight nominations and the darkly comic drama Three Billboards Outside Ebbing, Missouri, which is up for seven awards.

Who are the presenters?

The star-studded list includes: Gal Gadot, Lin-Manuel Miranda, Gina Rodriguez, Armie Hammer, Mahershala Ali, Chadwick Boseman, Viola Davis, Laura Dern, Jennifer Garner, Greta Gerwig, Tiffany Haddish, Tom Holland, Kumail Nanjiani, Margot Robbie, Emma Stone and Daniela Vega.

Who is performing?

The artists who sang this year’s five nominees for best original song onscreen will reprise their performances at the awards. 
Mary J. Blige will sing Mighty River (from Mudbound), Common and Andra Day will perform Stand Up for Something (from Marshall),Gael García Bernal, Miguel and Natalia Lafourcade will perform Remember Me (from Coco), Sufjan Stevens will perform Mystery of Love (from Call Me By Your Name) and Keala Settle will sing This Is Me (from The Greatest Showman).
The Oscar will go to the songwriters.

Will there be another envelope flub?

The Academy says (and sure hopes) not!
The Oscars vow to get the "envelope ritual" right at the 2018 Academy Awards, including a new procedure to make sure celebrity presenters confirm that they've been given the correct envelope for the category they are about to present.
