'Gavin And Stacey' star collapses on stage

Comedy actor Mathew Horne apparently collapsed on stage during a performance of 'Entertaining Mr Sloane' today.

The 30-year-old 'Gavin And Stacey' star was said to have fallen to the floor 15 minutes into the second half of the show during a scene with actor Simon Paisley Day.

Paisley Day called out for any doctors in the house to come forward, with Horne on the stage for 10 minutes before paramedics arrived, the BBC reported.

He was treated on stage before the manager asked the audience to leave the Trafalgar Theatre in London.

Co-star Imelda Staunton was also said to have walked on to the stage and apologised to the audience for the interruption.

A spokeswoman for the theatre said she was trying to establish what had happened and said the show would go on with an understudy tonight if Horne was too unwell.

Horne’s publicist was not immediately available for comment.

John Rigby, a BBC producer in the audience, told the BBC that Horne seemed “absolutely fine” during the first half of the Joe Orton play but that there was a delay after the interval.

It was announced the play would resume in three minutes, but a further 10 minutes elapsed before the actors took to the stage.

He said that the audience seemed to believe that Horne’s collapse was part of the show until fellow actor Paisley Day called out: “I think something has gone wrong, is there a doctor in the house?”

One audience member went to help while another called out for someone to dial 999.

An actor on stage replied: “Don’t worry, it’s been done”.

Horne fell with his back to the audience and did not move except to shake his head once while the ambulance crew was treating him, the BBC reported.

Rigby said: “I think everyone was just trying to show their concern for Mathew’s well-being.”

Horne has recently starred in 'Lesbian Vampire Killers' with James Corden.

The busy pair also have a sketch show on BBC3 called 'Horne and Corden', which has received mixed reviews.

The Bafta-winning duo became household names after the phenomenal success of the BBC show 'Gavin and Stacey'.

Last month, Corden said that the thought of being over-exposed was a “constant worry”.

Horne added: “We are very mindful of it, yeah, but you have to understand that a lot of that is not to do with us.”

Horne is not the only celebrity to be forced off the stage after becoming unwell.

Last year 'Doctor Who' star David Tennant had to sit out of the Royal Shakespeare Company’s production of 'Hamlet' for much of its London run due to a bad back.
