Cumberbatch is lone wolf in film
Benedict Cumberbatch will voice a secret agent wolf in upcoming animation The Penguins Of Madagascar.
Pictures unveiled from the upcoming movie - which is due to hit cinemas in November - show the Sherlock star reimagined as a debonair canine.
Benedict voices Classified, head of a covert protective force of animals, in the Madagascar spin-off, which sees the penguins on a mission to save their species.
The British actor said: "I don't know what it's like to be a penguin, but I do know what it's like to be a super-duper-smooth classified agent."
The film will also feature the voice of John Malkovich as octopus Octavius Brine - who also goes by 'Dave' - and is on a quest to wipe out the penguins.
The penguins - who already have their own TV series - take starring roles in the fourth Madagascar movie, following the success of the 2005 movie about a group of animals who escaped from New York Zoo.
Tom McGrath, who is executive producer and has been voicing the leader, Skipper, since the original 2005 animation said: "The penguins think there's no one better to save us than us."
Along the way, Skipper and his crew - brainy Kowalski (Chris Miller), rugged Rico (John DiMaggio) and young rookie Private (Christopher Knights) - end up joining forces with the high-tech animal organisation North Wind, whose motto is "No one breaks the Wind".
The movie will also feature the voices of Madagascar stars Ben Stiller, Jada Pinkett Smith, David Schwimmer and Chris Rock.
