THIS year's biggest film opens on general release tomorrow, but one of Harry Potter's biggest fans has already given the film his own personal critique.

Luther Frost-Barnes, the eight year-old cerebral palsy sufferer who is the beneficiary of the Gazette's Luther Appeal, is Potter mad.

Luther, of Cricketts Lane, Chippenham, saw the film at an advanced screening in Bristol last weekend and was a little disappointed it wasn't strictly in keeping with the book.

"He knows all four Harry Potter books off by heart," said his mother Lorraine, 40.

"He loved the film but because he knows the story so well he was a bit upset there were a few things missing."

Luther is a dead ringer for Harry with his round glasses, and Mrs Frost-Barnes, an artist, recently transformed his bedroom into a Potter paradise.

The youngster listens to the Harry Potter stories on tape while he is having three hours of therapy every day.

Last week Luther had another £500 session of treatment, at the Advance centre in East Grinstead and doctors there said they were delighted with his progress.

The treatment is being paid for by the appeal fund and, thanks to the generosity of Gazette readers, the fund now stands at more than £4,000.

"We can really see now that he is physically changing and we are delighted," said Mrs Frost Barnes "The therapy is really working for him."

Mrs Frost-Barnes' brother Johnny, who also suffers from cerebral palsy, started the therapy last month and is already beginning to see the benefits.

Mrs Frost-Barnes said listening to Harry Potter tapes keeps Luther amused during his therapy at home.

"He is totally obsessed with Harry Potter," she said.

In nearby Lacock more than 200 villagers are looking forward to a special wizardly day on Saturday, as Warner Brothers has given permission for a special showing of the film at Chippenham's Astoria Cinema.

The Marshfield Road movie theatre had advanced screenings of the film last weekend, with queues stretching all the way down the road.

On Saturday the Friends of Lacock Church will take over one of the screens to watch Harry Potter, and any villagers who were extras in the film will be admitted free.

Friends' chairman Richard Searight said the response to the film had been huge, particularly since the film had been shot largely around Lacock Abbey and at Castle Combe.

Any money made on ticket sales from the special showing, will go towards roof repairs at St Cyriac's Church, which are expected to cost £80,000.
