The president of the Academy of Motion Picture Arts and Sciences has said the organisation's response to Will Smith's infamous Oscars slap in 2022 was "inadequate".
Janet Yang said the incident was "unprecedented" and "unacceptable".
Smith stormed the stage at the 94th Academy Awards last March and slapped Chris Rock, following a joke the comedian made about Smith's wife, Jada Pinkett Smith.
Yang made the comments during her opening remarks at the annual Oscar Nominees Luncheon at the Beverly Hilton hotel in Beverly Hills on Monday.
"I'm sure you all remember, we experienced an unprecedented event at the Oscars," she said.
"What happened onstage was fully unacceptable and the response from our organisation was inadequate.
"We learned from this that the Academy must be fully transparent and accountable in our actions, and particularly in times of crisis we must act swiftly and compassionately and decisively for ourselves and for our industry.
"You should and can expect no less from us going forward."
In the aftermath of the slap, Smith, who went on to win Best Actor on the night, apologised to both Rock and the Academy.
He later resigned from the organisation and was banned from attending all Academy events for the next 10 years.
"We are committed to maintaining the highest of standards while creating the changes we wish to see in our industry," Yang told the audience on Monday.
"I want to remind us of the deep respect and love for our colleagues and for the art of filmmaking.
"I invite us to grow together, because the collective power of this room and this industry are unstoppable."
Among the guests at this year's luncheon were the stars of Martin McDonagh's dark Irish comedy The Banshees of Inisherin, Colin Farrell, Brendan Gleeson and Kerry Condon, who were joined by writer-director McDonagh and their fellow Irish nominees.
The 95th Academy Awards are due to take place on 12 March at the Dolby Theatre in Los Angeles - and will be hosted by US comedian and talk show host Jimmy Kimmel.
