A performance of Romeo and Juliet had to be stopped when the lead actress fell from the balcony during the play's best-known scene.
Laura Rees is recovering at home
Laura Rees suffered a badly bruised wrist and arm during the English Touring Theatre's production of the Shakespeare play in Malvern, Worcestershire, on Friday night.
The company said Ms Rees was taken to hospital and treated for minor injuries before she was released.
She fell about eight feet during the famous scene where Juliet asks from a balcony "Romeo, Romeo, wherefore art thou Romeo?".
Malvern Theatres, where the play is being shown, has refused to comment about the fall, but has confirmed that Saturday night's final performance has been cancelled.
Ms Rees, who has previously appeared in BBC programmes Holby City and Murder in Mind, is now recovering at her Northamptonshire home.
Drew Colverd, a spokesman for English Touring Theatres, who run the production, said it was unclear how Ms Rees fell off the balcony, but an inspection of the set had not uncovered any faults.
"The set has a balcony against the back wall and there's a large area for Laura to perch.
"It seems that Laura was simply acting her socks off, she was so engrossed in the part, and just leant out a little bit too far and she fell about eight feet," Mr Colverd said.
"In her own words, she got very carried away with the act and toppled over.
"She is absolutely fine and a little bit embarrassed, but thankfully she only had a few bruises."
He added: "It is very unfortunate that we had to cancel last night's performance and tonight's, but we are not the sort of company that employs understudies and there is no way we would expect Laura to carry on after what happened."
"Fortunately, we have a natural break now of around a week-and-a-half before we move on to Oxford for the next stage of the tour."
