Oscars to apologize to Native American actress Sacheen Littlefeather

The Oscars Academy says it will host an evening of "conversation, healing and performances" hosted by Native American activist and actress Sacheen Littlefeather.

The event will feature a formal apology to the actress who suffered decades of abuse within the industry following her appearance at the 1973 Oscars.

Littlefeather famously took to the stage to decline Marlon Brando's best actor award for The Godfather, at his request.

Instead, she gave a 60-second speech regarding the stereotypes and mistreatment of Native Americans in the entertainment industry, and the 1973 Wounded Knee protest in South Dakota.

On Monday, the Academy acknowledged that the actress, now 75, had been "professionally boycotted, personally harassed and attacked, and discriminated against for the last fifty years" following her actions.

"On September 17, join Sacheen Littlefeather at the Academy Museum for a night of conversation, healing, and performances as we reflect on the impact of her speech at the 45th Academy Awards (currently on view in our Academy Awards History gallery)," the organisation tweeted.

"Sacheen invites you to a special celebration of live Native American Indian performances featuring a long-awaited statement of apology from the Academy."
