A HARRY Potter fan who lost his sight has become an advisor to film company Warner Bros, helping it produce an audio-guide for its famous London studio tour.

The 12-year-old from Idle, who was diagnosed with rare children’s cancer Neuroblastoma in 2003, got the role after writing to the studios in Watford following a first visit.

His mum, Lisa Moorhouse, said: “When we went as a family he was really disappointed there was nothing for blind people, so he wrote them a letter and told them so.

“They were really lovely about it and invited him back to hear his ideas, and after that they created an audio tour and he’s been back to test it out.

“We’ve always taught Louis that you can’t change anything if you don’t tell people about it and he took that board.”

Louis, who is a pupil at Woodhouse Grove in Apperley Bridge, also had input when the National Media Museum hosted its recent Dr Who exhibition and now he has inspired the Yorkshire-based children’s cancer charity Candlelighters to produce its first ever braille newsletter.

Candlelighters community fundraiser Beth Kaminski said: “We were so inspired when we heard about the influence that Louis has had on the Warner Brothers studios that we decided to print our newsletter in braille so that children like Louis can stay up to date with Candlelighters’ news.”

As well as reading braille and sending letters, Louis’ other passions are making podcasts, swimming and music – playing the drums and keyboard. Just this week his band, The Rise, won the audience’s vote in a Battle of Bands contest at his school.

“There’s no stopping him in anything he wants to do. He’s a determined young man and gives everything his all,” his mum said.

A recent email from the Warner Bros studio tour said its staff had valued Louis’ input along with that from other families who had trialled its braille guides.

The Studio Tour’s communications co-ordinator Sara Mitchell added: “We are delighted to hear that Louis is continuing to be an inspiration.”
