The Academy Awards have issued a formal apology to an actress 50 years after she was booed off stage.
Native American activist Sacheen Littlefeather received the letter of apology from the Academy of Motion Picture Arts and Sciences, which oversees the Oscars.
Littlefeather appeared on stage at the 1973 Academy Awards ceremony on behalf of actor Marlon Brando who had refused to accept his best actor award.
Brando cited his support of Native American rights as his reason, referring to Native American activists protesting government inaction on treaties at the time.
Littlefeather made a speech denouncing the treatment of American Indians by the film industry, but guests at the awards show booed her off stage and made rude gestures.
