LONDON (AP) — Actor Ian McKellen said Monday he is withdrawing from a U.K. tour of his latest play because he needs more time to recover after falling off the stage at a London theater last month.

McKellen, 85, said his injuries “improve day by day.”

“It’s with the greatest reluctance that I have accepted the medical advice to protect my full recovery by not working in the meantime,” he said in a statement.

The “Lord of the Rings” star spent three nights in a London hospital after tumbling from the stage during a performance of “Player Kings” at the Noel Coward Theatre on June 17.

The play is an adaptation of William Shakespeare’s two “Henry IV” history plays, directed by Robert Icke. Several performances were canceled after the incident before the run resumed with understudy Devid Semark in the role of Falstaff.

Producers said Semark would continue to play the part during a national tour that runs July 3-27.

McKellen, who played Gandalf in the “Lord of the Rings,” and Magneto in the “X-Men” films, is one of Britain’s most acclaimed Shakespearean actors, with roles including Richard III, Macbeth and King Lear.

He has won a Tony Award — for “Amadeus” — several Olivier Awards, and has been nominated for two Academy Awards, five Emmys and several BAFTA awards.
