Written by Stephen Thompson and Steven Moffat, and directed by Douglas Mackinnon, the 5^th episode of Doctor Who's 8^th season, "Time Heist," is looking like one of the most thrilling of the series. Thanks to some preview clips and photos featuring Peter Capaldi, Jenna Coleman, the supporting cast and a menacing monster, we can assume that "Time Heist" will stick with us Whovians for a while! Let's take a look at these photos and videos to get a better clue about this episode, its plot and the mysterious new monster that the Doctor has never seen before! [SPOILERS to follow]

Director Mackinnon, who also helmed last week's intensely creepy-yet-moving "Listen," detailed what he and the writers wanted to accomplish with "Time Heist" according to The Daily Record (via Radio One).

"What we wanted to do was a heist movie for Doctor Who. I've watched virtually every heist movie there's ever been, and it incorporates things into it, but because it's Doctor Who, time travel is involved," he said. "There's a real time travel twist to it that's quite amazing - it starts with the TARDIS in Clara's flat, and the TARDIS phone starts ringing - very few people have that number, so when he picks up the phone, that's when the adventure begins."
