The first posters for the upcoming Spooks movie have been unveiled.

Described as “a high-octane espionage blockbuster”, the big screen spin-off of BBC One’s long-running spy drama arrives in UK cinemas on 8 May 2015.

Spooks: The Greater Good stars Kit Harington (Game of Thrones), Tuppence Middleton (Sinbad), Elyes Gabel (World War Z), Eleanor Matsuura (Utopia) and Jennifer Ehle (Pride and Prejudice), alongside Spooks stalwart Peter Firth, who appeared in every episode of the TV series, as MI5 chief Harry Pearce.

A trailer for the movie will go online at 8am tomorrow morning.

The official synopsis reads: “When charismatic terrorist Adam Qasim (Elyes Gabel) escapes from MI5 custody during a high profile handover, the legendary Harry Pearce (Peter Firth), Head of Counter-terrorism, is blamed. Disgraced and forced to resign, no-one’s surprised when Harry disappears one night off a bridge into the Thames…

“With MI5 on its knees in the wake of the Qasim debacle and facing controversial reform, former agent Will Holloway (Kit Harington) is brought back from Moscow to uncover the truth they feared – Harry’s still alive. He’s gone rogue, and needs Will’s help.

“As Qasim prepares his devastating attack on the heart of MI5 in London, Will must decide whether to turn Harry in – or risk everything by trusting the damaged, dangerous master spy who has already betrayed him once before…”

It emerged at the weekend that another classic Spooks character will appear in the movie.
