The latest Doctor Who series, starring David Tennant, will see BBC One's time traveller and his sidekick Rose tackle predators including a werewolf.
Doctor Who will face the werewolf in episode two
The second episode sees the Doctor face the creature - a man transformed into a wolf - in Scotland in 1879.
Tennant had his first outing in the role for last year's Christmas episode. The new series begins on Saturday.
He and co-star Billie Piper attended a Glasgow preview of the werewolf show although it was filmed in Wales.
Torchwood, a spin-off of Doctor Who, starring John Barrowman who plays Captain Jack in the series, is currently being filmed.
Written by Doctor Who executive producer and lead writer Russell T Davies, it will be shown on BBC One and BBC Three later in the year.
