At this point in the new series of Doctor Who, designer Stuart Manning's exclusive posters for every episode are almost as anticipated as the adventures themselves. After Deep Breath and Into the Dalek comes Robot of Sherwood, with Manning taking more retro inspiration from classic sci-fi.
"Gotta love a robot!" he enthuses, "This one has definite shades of Metropolis, particularly on the logo itself and the symmetrical robot image. It's a great, lurid episode title, so I took the lead from that."
"The end result is probably somewhere between a pulp novel and the packaging for a 50s tin-plate toy… I'd happily buy a wind-up Doctor Who robot knight, now you mention it."
