Kit Harington has been throwing himself into his new role, as the first footage from the Spooks film shows.

The Game Of Thrones star – who plays Will Holloway, the protege of MI5′s head of counter-terrorism Harry Pearce (Peter Firth) – joins the action in Spooks: The Greater Good.

Jennifer Ehle, David Harewood and Elyes Gabel also star in the big-screen adaptation of the BBC One spy TV series.

The film sees Kit’s character Will uncovering the truth when terrorist Adam Qasim (Elyes) escapes from MI5 custody during a high-profile handover.

Harry is blamed and forced to resign, and fakes his own death – so he can go rogue and find out what really happened.
