Doctor Who’s 770 Reference

By Kirby Bartlett-Sloan: I was watching the recent Doctor Who episode “Arachnids in the UK” for the second time when I noticed the room number the Trump-y character is standing in front of when he meets Team TARDIS, he having just escaped from a room containing a giant spider.

It was Room 770.

Coincidence, or is there an old-time fan on the production team making an obscure reference?

That is either a built set, meaning the room number was chosen when creating it, or it was location shooting – and I can’t imagine they would take the trouble to go to the 7th floor for the scene so again the room number was chosen by the production team.

I’m attaching screenshots and enhancements.
