They recruit the help of some famous faces ?including TV inventor John Logie Baird, played by the actor Kevin Eldon ?and bid to get back home. But they find time along the way to play some of the 21st century鈥檚 most famous tunes to their audience of Bright Young Things.

As well as Martins Bank, the show is also set to film at the Athenaeum this week.

Creator Daniel Lawrence Taylor said 鈥淵ou don鈥檛 see that many black people in period dramas, or in time machines, so I thought I鈥檇 try to write about both.

鈥淭here are so many great people on board and I can鈥檛 wait to get started鈥?

The Martins Bank building was designed by architect Herbert Rowse, who also designed India Buildings, the Mersey Tunnel entrances and ventilation shafts.

It opened in 1932 and during World War II its vaults housed most of Britain鈥檚 gold reserves. Martins was taken over by Barclays in the 1960s and

In 2015 it was announced that the building was to become an hotel.

The building was bought last year by the Principal Hayley Group, which wants to turn it into the city鈥檚 first five-star hotel.
