Sir Ian McKellen has been hospitalized after falling off stage during a performance of Player Kings at a theatre in London. The BBC reports that the 85-year-old actor was in a fight scene when he slipped and fell from the stage of the Noël Coward theatre. He cried out in pain as staff rushed to help.

The show was promptly canceled and the audience was asked to leave. Player Kings , a new version of Shakespeare’s Henry IV, Parts One and Two adapted by Robert Icke, has been at the theatre since April. McKellen plays John Falstaff alongside Richard Coyle and Ted Lasso ’s Toheeb Jimoh.

The BBC reports that one member of the audience described the incident as “very shocking”. “I really hope that he is going to be alright,” Sandro Trapani said. “As far as I saw, he was conscious because he was asking for assistance.

” The Independent has reached out to McKellen’s representatives and the Noël Coward theatre for comment. Earlier this week, McKellen said that he’d like to appear in a recently announced Lord of the Rings film “if I’m alive”. He famously played Gandalf in Peter Jackson’s blockbuster JRR Tolkien adaptations, and it has been rumored he will reprise the role for a new movie centred on Andy Serkis’s Gollum.

Those rumors began after Warner Bros announced The Hunt for Gollum last month , and McKellen confirmed in a new interview that there are “stirrings in Tolkien land”. Speaking to The Times , McKellen said he has heard that Gandalf will.
