Sir Ian McKellen, 85, reveals he suffered 'injuries to wrist and neck' after shocking stage fall during West End show that left him hospitalized for three days

Sir Ian McKellen got candid about the injuries he suffered after his shocking stage fall during a West End production two weeks ago.

The 85-year-old X-Men alum — whose recovery was aided by his BFF Anthony Hopkins — took to his X on Tuesday to share an update after he revealed he had pulled out of the national tour of Player Kings a day before. 

'Just two weeks after my accident onstage I want to assure my many well-wishers that the injuries (to wrist and neck) are on the mend,' he wrote. 'My doctors promise a complete recovery - but only if I avoid work over the next few weeks.'

Sir Ian was playing John Falstaff in a production of Player Kings at the Noel Coward Theatre on June 17 when he lost his footing in a fight scene and plunged from the stage into the audience. 

After the shock incident, he was rushed to hospital to receive treatment and the remainder of his performances for the week were cancelled to allow him to rest. 

'Meanwhile the show goes on and the Player Kings company start their four weeks’ tour without me,' Ian continued on X. 

'Any actor will say that missing a performance feels somewhat shameful, even when he is not to blame. None of us ever wants to let down our audience,' he added.

Sir Ian announced last Thursday that he was having 'physiotherapy, light exercise and a lot of essential rest at home' after three nights in hospital.

The actor was in a scene involving the Prince of Wales and Henry Percy when he fell off the front of the stage, and was heard to cry out in pain as staff rushed to help.

In his statement last Thursday, Sir Ian said: 'After three nights in hospital, the effects of my fall onstage have been fully analysed and I'm now having physiotherapy, light exercise and a lot of essential rest at home.

'Meanwhile, my part in Player Kings is filled by the redoubtable David Semark supported by Robert Icke's amazing production and cast. 

'The many messages of love and support will, I am sure, aid the speedy recovery that my doctors have promised me.'

Player Kings, a production of Henry IV, parts one and two, adapted and directed by Robert Icke, ended its run at the Noel Coward Theatre on Saturday.

The play will then move to the Bristol Hippodrome next month before being staged in Birmingham, Norwich and Newcastle.

A post on the Player Kings X account said last Thursday: 'David Semark will be playing the role of Sir John Falstaff for the final three scheduled performances of Player Kings at the Noel Coward Theatre in London while Ian McKellen recuperates following his fall on Monday 17 June.'

It added: 'We look forward to Ian returning to the production, which begins a national tour in Bristol on Wednesday 3 July, before visiting Birmingham , Norwich and Newcastle.'

Last Friday, audience member Johanna Dart described the dramatic moment Sir Ian McKellen 'flew head first' into her when he fell off stage, adding: 'Getting crushed by Gandalf the Grey, that's something you don't expect.'

Ms Dart, who was in the front row, said Sir Ian seemed to trip on a stage prop before falling – with his head hitting her knee 'quite hard'.

The 30-year-old, from Leatherhead, Surrey, was later pictured sobbing in hospital where she said she was taken with soft tissue injuries after the incident.

Understudy David Semark, 52, is taking his place as Falstaff, Shakespeare's irreverent comic character. Semark said Sir Ian had called him to let him know he would be playing the role.

He said: 'The first person I heard it from was Sir Ian. We then had a discussion about the role... But I am holding a place open for Sir Ian. I walk in the shadow of greatness.'

Audience member Paul Critchley said last Monday that it was a 'shock' to witness the fall.

The Methodist minister from Downham Market, Norfolk recalled how Sir Ian seemed to trip as he moved downstage to take a more active part in the scene before falling off the stage directly in front of the audience.

Sir Ian's career has spanned more than six decades and seen the actor perform at theatres around the country.

On screen he is best known for playing Magneto in the X-Men films and Gandalf in Peter Jackson's fantasy trilogy, based on the books from JRR Tolkien.

On the stage he has played a number of Shakespearean characters including Richard II, Macbeth, Coriolanus, and King Lear.

His many acting credits have led to a number of accolades over the years including several Olivier Awards.

A spokesman for the Noel Coward Theatre said: 'We are very sorry this rare accident occurred during a performance of Player Kings.

'We maintain the highest standards of safety and are conducting a thorough investigation with the producers.'
