“There's a deliberate old-school vibe to Yana. He speaks in that slightly archaic way of classic Doctor Who - a bit gentlemanly, a bit out of his time, saying things like "So it would seem". Even when he becomes the Master, he uses that old classic, "My dear" - a phrase that we'd banned from the modern-day Doctor, because it sounds so wonderfully Pertwee. But suddenly here was a character who fitted the phrase.”

Doctor Who: Utopia

Chantho
"Bless her. What can I say?! Chan love her tho. And incidentally, her spine showing through her coat which we wanted to have was too expensive in the end!"

The Master Regeneration
"Utopia had to be very low on FX shots - a couple of digital matt paintings for the city, and a 2D rocket instead of a 3D one - to save money just for this sequence. The Mill gives us little presents sometimes , and that shot of John Simm with the glowing eyes after the Doctor's seen the tardis windows glowing was added on at the very last minute as a gift. So last minute in fact that Murray Gold's copy didn't include it - so all his music cues were a couple of secnds out afterwards and had to be rearranged! there's no such thing as a free FX shot!"
