Film crews outside York's Bettys Tea Room and Mansion House

Past the bustling scenes at York Food Festival and the usual queues outside Bettys Tea Rooms, tour guides are telling excited tourists about the city's past cameos in film and TV.

"We have been expecting some filming in the next week or two, so this must be it," one tour guide tells his group.

"Sometimes they keep it quiet."

The filming is taking place at York's Mansion House over the next two days while the former Post Office in Lendal appears to be in use too.

Film and TV lighting company PKE Lighting - which has helped bring productions like Broadchurch, Sherlock and Dr Who to life - are parked up in St Helen's Square.

But anyone looking to spot the stars today might be disappointed with extras expected to be the only cast members on set today.

The Press understands the filming is for upcoming ITV period drama.

It marks another moment in the spotlight for Mansion House - one of several buildings used in filming for ITV's Victoria, historical television drama series featuring former Dr Who star Jenna Coleman.
