McKellen is expected to make a full recovery, the Associated Press reported, citing a theater spokesperson. Representatives for McKellen did not immediately respond to requests for comment.
McKellen was playing Sir John Falstaff — one of Shakespeare’s most famous comic characters, who appeared in four of his plays.
Shakespeare is thought to have drawn satirical inspiration for the character from Sir John Oldcastle, a powerful nobleman and soldier who was convicted of heresy. Early versions of the play bear his name, but it was changed, probably at the urging of his descendants, according to Shakespeare scholars.
In a statement shared on social media by staff of British theater publication the Stage, the producers of “Player Kings” thanked the audience and public for their well wishes after the actor’s fall.
Following a scan, doctors have said McKellen will “make a speedy and full recovery” and he is “in good spirits.”
Tuesday’s performance was canceled so the actor can rest.
