Tom's attic was built in the Highfields Centre in Highfields Road.

The attic is the scene of some of the show's most eerie supernatural activity, and is lit up with candles and a roaring fire when Tom's young neighbours sneak into his house.

The Highfields Centre building is just outside the town centre, in an area renowned for unusual architecture. It's home to Kirklees College's performing arts students.

The students got the chance to meet and work with Michael Palin, Mark Addy and Julia Sawalha on set.

Performing arts student Will Green said: "I would love to be a comedy writer and actor like Michael Palin so when I was offered the chance to work with him I thought it would be an amazing opportunity.

“He was incredibly down to earth and had a lot of time to talk to people. He gave me a lot of advice and tips about how he started out."
