A brand-new trailer for "Doctor Who: Robot of Sherwood" has been released, showing the Doctor and Robin Hood in an unusual "sword" fight.

This coming weekend's adventure sees the TARDIS materialise in Sherwood Forest, home to the legendary Robin of Locksley — a.k.a. Robin Hood — someone, the Doctor insists does not exist.
Written by Mark Gatiss (Game of Thrones) and directed by Paul Murphy, Robot of Sherwood follows the Doctor and Clara as they unearth "an evil plan from beyond the stars [and with] all of Nottingham at stake, the Doctor must decide who is real and who is fake."
Described by Den of Geek as somewhat "Arrow-esque in [its] parkour-style moments",
The third episode of Season 8, Doctor Who: Robin of Sherwood stars Peter Capaldi as the Doctor, Tom Riley as Robin Hood and Jenna Coleman as Clara Oswald portaying an ersatz Maid Marian. Riley is already well-known to genre fans for his role as in Da Vinci's Demons, the Starz-produced American historical fantasy drama series that is filmed in Swansea, just down the road from Doctor Who's Cardiff home, in Wales, in the UK.
Other cast members include Ben Miller (Death in Paradise) Joseph Kennedy as Will Scarlett and Ian Hallard (An Adventure in Space and Time).
An earlier trailer for the episode, and a clip for the following one, Listen, can both be viewed elsewhere on Digital Journal.
