This month we endure six hours in make-up to bring you three Doctor Who adventures notable for their use of prosthetic masks (to varying effect). First up, it's off to the planet Dido [N.B. CHECK SPELLING], where the First Doctor makes a new friend, and Ian and Barbara are ready for cockylickin'. Then we drop by Oodsphere, where the Tenth Doctor and Donna encounter Spartacus with tentacles and a huge, ever-growing pulsating brain. And finally, a long-awaited return to Telos, where the Cybermen are getting nostalgic and Sarah Greene is encased in sticky-back plastic. Along the way, we ponder the UK space programme, what it's like to be at a dreary sales conference, and exactly what's wrong with Eric Saward's writing.
