The Bristol Old Vic is to appeal for money from the public

Bristol Old Vic needs �2m as part of a �7m redevelopment fund, and plans to close until the end of 2008 from this summer for work to be completed.

But it has warned that if this fails, the theatre could be forced to close for good.

The appeal comes after the Tobacco Factory, Bristol's other main theatre, asked for money from its audiences and the business community.

Minister for Culture, David Lammy, said he was confident the Bristol Old Vic would survive.

But the actors' union Equity called the situation "outrageous".

Audiences have not liked the programme and it is a very uncomfortable auditorium Clarie Middleton, Bristol Old Vic

Mr Lammy MP said: "We have seen ups and downs in regional theatres across the country in other cities.

"They have all survived ultimately. I have no doubt that... we can see life brought back to this theatre in due course."

The Bristol Old Vic has previously admitted to perilous finances because of production overspending and falling audiences.

Equity has demanded a full and rigorous investigation and a clear statement from the Bristol Old Vic Trust about its plans for the future.

Malcolm Sinclair, of Equity, said: "If the theatre closed, it would have a very bad effect on the profession. It is perhaps the leading regional theatre."

'Popular pieces'

But Clarie Middleton, from the Bristol Old Vic, told BBC Points West the theatre would reopen after the refurbishment.

"We've got to do popular stuff and pieces that will stimulate, she said.

"Audiences have not liked the programme and it is a very uncomfortable auditorium. These two things are being addressed."
