Unlike recent awards ceremonies such as the Golden Globes, Baftas and Emmys, the Oscars have asked nominees to attend one of the locations in person.
Mank leads the nominees with 10, but is unlikely to win the night's top prizes.
Instead, films including Nomadland, Minari, and Ma Rainey's Black Bottom could perform strongly in some of the major categories.
The main elements of the ceremony will come from Los Angeles, as usual. The event will be split across two venues in the city - the Dolby Theatre and Union Station.
