Will Smith has tendered his resignation from the body that awards the Oscars after his attack on Chris Rock during the weekend ceremony, a statement said Friday.
"I am resigning from membership in the Academy of Motion Picture Arts and Sciences, and will accept any further consequences the Board deems appropriate," the actor wrote in a statement carried by multiple outlets.
"My actions at the 94th Academy Awards presentation were shocking, painful, and inexcusable.
"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."
Attendees at the Dolby Theatre watched open-mouthed as Smith mounted the stage and slapped Rock across the face after the comic made a joke about his wife's closely cropped head.
Jada Pinkett Smith has alopecia, a condition that causes hair to fall out.
"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."
