Get ready, movie lovers: Stars will descend on the Dolby Theatre in Hollywood on Sunday night to celebrate the 90th annual Academy Awards.
This year, Guillermo del Toro’s “The Shape of Water” has the most Oscars nominations, leading with 13. That’s just short of "All About Eve," ''Titanic" and "La La Land,” which all received a record-setting 14 nods in the past.
Ahead of one of the film industry's glitziest events, here’s what you need to know.

The Oscars, also known as the Academy Awards, are presented at a ceremony honoring the film industry. The event is hosted annually by the Academy of Motion Picture Arts and Sciences.
Each year, a total of 24 awards are given out. The categories include best picture, lead actor, lead actress, supporting actor, supporting actress, best director, animated feature, animated short, adapted screenplay, original screenplay, cinematography, best documentary feature, best documentary short subject, best live action short film, best foreign language film, film editing, sound editing, sound mixing, production design, original score, original song, hair and makeup, costume design and visual effects.
Winners receive a gold statue that is formally called an “Academy Award of Merit.”

Aside from “The Shape of Water,” “Three Billboards Outside Ebbing, Missouri” and “Dunkirk” fared well, with seven and eight nominations, respectively.
“Dunkirk,” Christopher Nolan’s World War II epic, has most of its nominations in technical categories. Additionally, Nolan also received a nod for best director for the first time.

Actresses Eiza González, Ashley Judd and Nicole Kidman will present as well, the show's producers said, along with Matthew McConaughey, Helen Mirren, Rita Moreno, Lupita Nyong’o and Christopher Walken.
Why is the award called an Oscar?
While no one knows for sure how the statuette got the nickname, an urban legend says the name came about after Margaret Herrick, a librarian for the Academy, said the statuette resembled her uncle whose name was Oscar. The Academy first used the nickname in 1939, a few years after the moniker officially came about.
{{#rendered}} {{/rendered}}What actors and actresses have the most-ever Oscar nominations?
Meryl Streep, Katharine Hepburn and Jack Nicholson have the most-ever nominations. Streep has 21 nominations and three wins. This year, she’s up for best actress for her role in “The Post.”

Preventing last year’s envelope mix-up
Last year, an infamous envelope mix-up led to "La La Land" being incorrectly announced as the best picture before "Moonlight" was crowned.
PricewaterhouseCoopers (PwC) is an accounting firm that counts the votes and keeps the results a secret prior to the event. During the Oscars, PwC officials stand backstage and hand presenters the envelopes before they walk on stage to announce the winner.
{{#rendered}} {{/rendered}}But last year, Warren Beatty, who announced the best picture award alongside Faye Dunaway, was accidentally handed an envelope for best actress instead of best picture — ultimately leading to the mistake.
This year, to prevent another mishap, the academy has prohibited the PwC accountants who handle the envelopes from using cell phones or social media during the show. Several other reforms were announced ahead of the awards show, including the addition of a third balloting partner in the show's control room.
