According to a statement from the Manchester International Festival, "An actor was hurt during one of the fight scenes in a performance of Macbeth on Wednesday night. MIF has qualified medics on site during each performance and the actor was assessed and told he was fine to continue on with the evening's performance. The actor was taken to hospital afterwards as a precaution."

The actor, who was unnamed, was said not to have been one of the production's "big stars." In a radio interview broadcast earlier the same day that the incident took place, Kenneth Branagh had said, "The battle is very precisely rehearsed every single day, and in doing it there is enormous concentration. It is impossible to say that it is without danger. Metal clashes, sparks literally fly. We wanted to immerse the audience in an elemental experience."

The entire run is sold out, but the performance on July 20 will be filmed and broadcast to cinemas in the U.K. and around the world through NT Live. For further details, visit http://ntlive.nationaltheatre.org.uk/productions/ntlout4-macbeth.
