Shooting films and television shows in UK locations boosts their tourist appeal, new research has shown.

Alnwick Castle in Northumberland was the setting for Harry Potter's Hogwarts school. It has seen an estimated rise in trade of 120 per cent, according to the survey.

It was commissioned by various tourist bodies and shows stately homes, historic and religious buildings and village locations are most likely to benefit from a star appearance.

Lincolnshire's Burghley House recorded a 20 per cent jump after it featured in the Pride and Prejudice movie while Lyme Park, Cheshire, saw triple the visitors after its role in the television production of the story.

John Woodward, chief executive of the UK Film Council, commented: "British films and television programmes play a powerful role in showcasing the UK to the rest of the world and boosting tourism.

"There are countless examples of visitors flocking to locations they’ve seen in films or on TV and the effect can last for years."

Margaret Hodge, minister for film and tourism, added: "We have beautiful scenery and awe-inspiring buildings across the length and breadth of Britain.

"Our thriving film and television industries provide a platform to show the rest of the world just how much we have to offer."
