Sacheen Littlefeather has formally accepted The Academy's apology after being heckled at the 1973 Oscars.

The 75-year-old actress and Native American civil rights activist was booed at the awards ceremony when she spoke to refuse an Oscar on behalf of Marlon Brando – who had won the Best Actor gong for The Godfather – as he declined the accolade because of the treatment of Native Americans in the film industry at the time.
