The 90th Academy Awards begins at 8 p.m. EST and will be broadcast live by ABC from the Dolby Theatre in Los Angeles.

The ceremony, to be hosted again by Jimmy Kimmel, will be the crescendo of one of Hollywood’s most tumultuous awards seasons ever — one that saw cascading allegations of sexual harassment topple movie moguls, upended Oscar campaigns and new movements launched to improve gender equality throughout the industry.
