Stuart Linnell MBE added: 'Watching Dr. Who. Like the police officer just said 'it's the night shift in Sheffield. Everything's out of the ordinary.'

'That's just how I remember it from the 70s. Great city.'

Another viewer tweeted: 'Great line in Dr. Who  '˜We don't get aliens in Sheffield' '“ are they sure?' 

Others were excited to spot Sheffield landmarks in the show. 

One said: 'This Dr. Who episode is filled a lot with Sheffield. I just recognised our bus station.'

Meanwhile Robert Ham' was hoping for a famous cameo or two.

He tweeted: 'With the first Dr. Who episode taking place in Sheffield, I'm hoping for a cameo by Jarvis Cocker.

'Or at least one of the members of Def Leppard.'

The new show premiered on BBC1 tonight but the stars, including the Timelord herself and co-stars such as Bradley Walsh, were recently treated to a preview at a red carpet event held at The Light Cinema in Sheffield.
