The repercussions of the revelations about intelligence gathering by American and other surveillance services made by US whistleblower Edward Snowden have proved huge. Laura Poitras’s documentary CitizenFour is no less revelatory about the process of their appearance, about just how Snowden came to be in that Hong Kong hotel room with reporter Glenn Greenwald, and what happened there.

The TV series on which Guy Ritchie has based his new spy-buddies movie first appeared on the small screen (in black and white) in 1964, when Napoleon Solo and Illya Kuryakin welcomed us into their secret lair in New York and introduced themselves as "enforcement agents" for U.N.C.L.E., apparently a sort of UN/CIA hybrid. The grandfatherly Mr Alexander Waverly, resembling a retired bank manager in venerable tweed, announced himself as their boss.

The idea of a movie spin-off from BBC One's spy show Spooks has been lurking with intent ever since the tenth and final series ended in 2011. Finally it's here, helmed by director Bharat Nalluri (who shot the first and last episodes for TV) and with Peter Firth's Sir Harry Pearce at its centre. Where, as the Spookfather-in-chief, he had to be.

During its 10-season run on BBC One between May 2002 and October 2011, Spooks built a lasting reputation as a superior espionage thriller, charting the battle of a squad of MI5 agents to protect the realm against its fiendish and unscrupulous adversaries. Despite the inevitable plot-holes and sometimes incredible storylines, Spooks managed to keep itself anchored in the bleak realities of intelligence work, where it was wise to trust nobody and if you were paranoid, that's because the bad guys really were out to get you.

Rum old business, espionage – at least in the way we Brits are still pursuing it. For all the reality that the existential threat has long moved locations, in its television incarnations we remain addicted to the Cold War, the attraction to those gloomy postwar years seemingly a fatal one. The BBC’s new spy drama The Game was back in prime le Carré territory and the early Seventies, with industrial unrest and power cuts further turning down the visual wattage.

“The righteous traitor” must be as provocative a subtitle as any when the subject is espionage. Director George Carey nevertheless used it in this highly revealing film about George Blake, the “spy who got away”, which proved as much about the anatomy of treachery – its correlation with the uneasy relationship of the outsider to a dominant establishment – as it was an investigation of the intelligence world in which Blake played so notable a role.

Imitation is the sincerest form of flattery, the saying goes – and Kingsman: The Secret Service is a cracking part-homage, part-pastiche of the James Bond franchise (and other British spy movies) done with knowing comedy, élan and obvious affection. It's based on The Secret Service comic book created by Dave Gibbons and Mark Millar, and is directed by Matthew Vaughn (Kick-Ass, X-Men First Class), and here he reunites with Jane Goldman, who also provided scripts for his previous works.

No one could have known it would be one of his final screen appearances – there’s another still to come in a further installment of Hunger Games – but Philip Seymour Hoffman’s role in Anton Corbijn’s A Most Wanted Man proved, with hindsight, a fitting farewell. This was Hoffman living the part, as on-the-edge, largely off-the-radar Hamburg spymaster Gunter Bachman, whose life and professional energy seems fuelled by cigarettes and whisky.

The recent comedy awards on Channel 4 threw up little in the way of surprises – or, indeed, laughter for that matter. It was, however, notable for the first real-time, on-screen mugging at an awards bash, as Harry Enfield strolled off with the Best Comedy Actor gong, leaving Mathew Baynton looking very much the wronged man. That James Corden wasn’t even nominated was another crime.

Finding a clear narrative among the deadly uncertainties of the long-lasting stand-off between Israel and Palestine is a challenge. Israeli documentarist Nadav Schirman, drawing on a real-life story, has honed The Green Prince down into a bare story of the ongoing contact between Gonen Ben Yitzhak, an officer of Israel's Shin Bet intelligence service, and Mosab Hassan Yousef, a young man from the very centre of the Palestinian leadership who becomes his agent.
