The bulk of Doctor Who Series 7, episode six (rumoured to be called The Bells of St John), written by Steven Moffat has been completed, with a high-profile shoot in London taking place last week.

Incorporating motorcycle antics on the south bank and around Westminster streets, plus scenes in the shadow of the Shard near London bridge – the shoot finished off with some pickups on Wednesday back at Senedd building in Cardiff.

Director Colm McCarthy wryly tweeted:

Five cameras on a corner of a street in Cardiff shooting Dr Who for an hour. Nobody has noticed yet. Too late Whovians! We’re out of here.

Joining Matt Smith and Jenna-Louise Coleman for the first episode of Series 7b will be Celia Imrie – who has previously appeared alongside Jenna in Julian Fellows damp squib, Titanic, last April – in this modern-day Earth based story which will be the first story to air in Doctor Who’s fiftieth anniversary year.

Also in the episode are: Robert Whitelock (The Hour), Matthew Earley (Life’s Too Short), and Dan Li (Ideal).
