Doctor Who: 10 Terrifying Moments In Under The Lake

10. Moran Returns From The Dead

Audiences had already caught their first glimpse of Paul Kaye's Victorian Gentleman-style ghost onboard the ship but it wasn't until the terrified crew started running for their lives that they - and the audience - got their first proper look at the ghosts stalking them.

Having died just a moment earlier, Moran's appearance in the corridor is chilling. Black chasms where his eyes should be and shrouded in a misty glow, he looks the stuff of nightmares. And while audiences will have seen his ghost plenty of times in the trailer, seeing him appear for the most time is the first of many chills Under The Lake presented.
