A £500,000 scheme to transform Wallingford's town centre Corn Exchange theatre has been unveiled.

If all goes well and fundraising hits the target, the new facilities will be opened in time for the Players' Diamond Jubilee year in 2008. The theatre in the listed Corn Exchange is the face of Cawston Theatre in the Midsomer Murders TV series.

But in real life it is the home of the Sinodun Players and the town's cinema.

Lack of space means they cannot operate simultaneously, but the plans would give both a permanent venue.

Theatre trustee Chris Harris said: "If we are able to offer a wider range of drama without curtailing the films we present, we shall secure the future and offer Wallingford an even better entertainment venue."

The scheme includes improving the theatre bar, lavatories and public access, together with upgraded backstage facilities.

The Corn Exchange is a Grade II listed building and celebrates its 150th birthday next year.

It was converted to its present use in the 70s.

Mr Harris said: "Before this can become a reality there will be a major fundraising programme."

The plans will be on show in the Corn Exchange from 10am to 3.30pm on Saturday, October 8.

People are being asked to comment on the proposals before a finalised plan is submitted to South Oxfordshire District Council.
