Will Smith has resigned from Oscars organiser the Academy.
He has said he "betrayed the trust" of the Academy of Motion Picture Arts and Sciences as he resigned from the organisation following his altercation with Chris Rock last Sunday night.
In a statement, Smith said: "I have directly responded to the academy's disciplinary hearing notice, and I will fully accept any and all consequences for my conduct.
"My actions at the 94th Academy Awards presentation were shocking, painful, and inexcusable."
He added: "The list of those I have hurt is long and includes Chris, his family, many of my dear friends and loved ones, all those in attendance, and global audiences at home.
"I betrayed the trust of the academy. I deprived other nominees and winners of their opportunity to celebrate and be celebrated for their extraordinary work. I am heartbroken.
"I want to put the focus back on those who deserve attention for their achievements and allow the academy to get back to the incredible work it does to support creativity and artistry in film.
"So, I am resigning from membership in the Academy of Motion Picture Arts and Sciences, and will accept any further consequences the board deems appropriate.
"Change takes time and I am committed to doing the work to ensure that I never again allow violence to overtake reason."
Smith's resignation means he loses his voting rights, but he can still be nominated for an Oscar and win an award for any upcoming performances.
The film academy says it has accepted Smith's "immediate resignation" from the organisation and will "continue to move forward" with its disciplinary proceedings against him. The details of which are to be discussed at a board meeting on 18 April.
