The organisers of the Oscars have said they “condemn” Will Smith’s attack on Chris Rock and have opened a formal review into the incident.

In a statement the film academy said it will also “explore further action and consequences in accordance with our Bylaws, Standards of Conduct and California law”.

The former Fresh Prince, who won the best actor gong for his role in biopic King Richard, was reacting to a joke Rock had aimed towards Smith’s wife, Jada Pinkett Smith.

Referring to Pinkett Smith’s shortly shaved hair, Rock said: “Jada, can’t wait for GI Jane 2.”

Smith can be seen initially laughing at the joke, however Pinkett Smith rolls her eyes and clasps her hands, looking unimpressed with the jibe.
