London Rules – explicitly cover your arse – is the fifth in the most remarkable and mesmerising series of novels, set mostly and explicitly in London, to have appeared in years.

It’s not the first time that James Norton has kicked off BBC One’s New Year primetime celebrations in Russian style. Two years ago, he was costumed up as the courageous Prince Andrei, in illustrious ensemble company for Andrew Davies and Tom Harper’s War and Peace.

The play that famously got away when one of its stars (quite literally) jumped ship is back. In 1995, Stephen Fry abandoned the West End premiere of Simon Gray's espionage drama Cell Mates, leaving co-star Rik Mayall in the lurch and prompting Gray to write a particularly dyspeptic account of the bizarre goings-on called Fat Chance.

“There is something odd, I suppose, about anyone who betrays their country.” It’s an excellent opening line, particularly when delivered in director George Carey’s nicely querulous narrative voice, for Toffs, Queers and Traitors (BBC Four).

Over his long career – 23 novels, memoirs, his painfully believable narratives adapted into extraordinary films (10 for the big screen) and for television – John le Carré has created a world that has gripped readers and viewers alike.

Summer's here, which can only mean Hollywood blockbusters. But it's not all Spider-Man, talking apes and World War Two with platoons of thespians fighting on the beaches. There's comedy, a saucy menage-à-trois, a film about golf and even a ghost story. It's called A Ghost Story. We hereby bring you sneak peeks of the season's finest and more titles anticipated in the autumn (and hey, the trailer might even be the best part).

AUGUST

Bowie’s “Cat People (Putting Out Fire)” plays as Charlize Theron’s Lorraine Broughton makes her entrance. She’s the last Cold War super-spy, a female Bond sent to Berlin as the Wall crumbles. “Killer Queen”, prominent on early trailers, would have done just as well. Daniel Craig in Casino Royale is the last time an action star made such a startling bow.

It was a long time coming, but Homeland’s sixth series at last awoke from its early-season slumbers to put on a late surge over the closing episodes. For a while, it had seemed that the story was barely advancing at all, as the screen was self-indulgently hogged by Carrie Mathison’s emotional life, particularly her anguish over her daughter being taken into care.

The big surprise of this new-season opener of Homeland was that black ops specialist Peter Quinn (Rupert Friend) didn't die at the end of series 5 after all, despite the fact that we last saw him apparently moribund in his hospital bed, having penned a poignant adieu to sometime paramour Carrie Mathison. But, after surviving a hefty dose of sarin gas, he isn't the man she used to know.

As an old Sixties lefty brought up on paranoia-infused thrillers like The Parallax View or All the President's Men, Oliver Stone loves ripping open great American conspiracies. However, in contrast to his earlier labyrinthine epics Nixon and JFK, this account of CIA whistleblower Edward Snowden keeps clutter to a minimum as Stone fashions a tense, fast-moving drama which will leave you pondering over what's really justifiable for the greater good.

It's no great surprise to find that Stone portrays Snowden as a noble crusader for free speech and democratic accountability against the might of America's intelligence agencies, and if you happen to work for the CIA you'll hate this movie, but Stone makes Snowden's journey towards his fateful decision to spill the top-secret beans plausible and persuasive. Joseph Gordon-Levitt's Snowden (many of whose family were federal lawyers or in the US military) starts out as a sincere young patriot, training for Special Forces but rejected as not physically strong enough to make the cut (pictured below). A computer genius who's keen to serve his country, he joins the CIA instead and whizzes through the admission tests with astounding ease.

However, as he's given various postings around the world, he becomes disillusioned at how the CIA and National Security Agency are abusing their seemingly unlimited powers. He's shocked at the way Timothy Olyphant's Geneva-based CIA operative cynically compromises a contact and blackmails him into becoming an informant, then later is horrified by the way a programme he helped create, EpicShelter, is being used for marking targets for extermination in drone attacks.

The sheer extent of what the Americans were, or are, up to remains flabbergasting, with the NSA supposedly capable of tracking every mobile phone on the planet, though it's supposedly all justifiable in the name of national self-defence. They're trying to "find the terrorist in the internet haystack", as Snowden's CIA trainer Hank Forrester (Nicolas Cage) puts it.

"You didn't tell me we were running a dragnet on the whole world," Snowden protests to his boss Corbin O'Brian (Rhys Ifans), who likes to point out that "the front line is everywhere". For the the O'Brian role, Ifans (pictured below) has assumed a gravelly baritone loaded with menace, and seems to be channelling Jason Robards and Scott Glenn as he looms ominously from the screen in giant close-ups. 

Stone isn't known for his light romantic touch, but he handles Snowden's complicated relationship with girlfriend Lindsay Mills (Shailene Woodley) deftly, and the way that Agency suspicions about Snowden's attitude to his work start to cast paranoid shadows over the couple's private life effectively personalises the broader picture. Indeed, the degree of intrusion which intelligence operatives are subjected to by their employers is a fascinating aspect of the tale.

Scenes of Snowden hiding out in Hong Kong while Guardian journalists prepare to publish his reams of top-secret revelations tend towards melodrama (Tom Wilkinson seems to share only the most only tenuous of connections with defence correspondent Ewan MacAskill, while Joely Richardson makes an unfeasibly actressy hash of Janine Gibson, editor of Guardian USA). Melissa Leo's portrayal of Laura Poitras (who made the Snowden documentary Citizenfour to which Stone's movie is quite heavily indebted) is marred by the malevolent creepiness Leo brings to every role.

However, Gordon-Levitt is pitch perfect in the title role, gradually revealing the steely inner core behind his nerd-like exterior, and skilfully evoking Snowden's process of disillusionment as he sees more and more of the skull beneath the skin of his homeland. Overall, this is a much better film than Stone's recent history might have led you to anticipate.
