You certainly wouldn’t let her in, would you? Today’s image  sees Doctor Who star David Tennant and his Waters of Mars co-star Lindsay Duncan seperated from a “water zombie” (as we’re calling them here at K Towers) by a plate of glass.

Broadcast this Sunday, 15th November, The Waters of Mars has got all the hallmarks of a classic Doctor Who episode, combining the base under siege storytelling best seen in classic episodes The Moonbase (1967), The Seeds of Death(1969), Inferno and even as recently as 2006’s The Satan Pit with alien takeover body horror, an aspect that again echoes 1970’s Inferno.
