Americans are chastised, often wrongly, for possessing a scant sense of irony, so I mean it as no criticism whatsoever of The Kids Are All Right to point out that the title of Lisa Cholodenko's wonderful film is altogether un-ironic. In less caring or careful hands, or a not so fully empathic context, this might be a portrait of irretrievably damaged youth with the parents deemed responsible, of the sort that proliferates on the London stage.

John Landis will always be loved for writing and directing An American Werewolf in London (1981), the definitive horror-comedy. That - and The Blues Brothers, and Trading Places - was reason enough for Simon Pegg and Andy Serkis to agree to star as 19th-century grave-robbers Burke and Hare in Landis’s first feature for 12 years.

This first feature from Swedish writer-director Ruben Östlund arrives heavy with awards, the seasoned and decorated product of film festivals across Europe. Brutal, quirky and elegantly self-conscious, it does little to challenge the trends that have recently made Swedish cinema (Let The Right One In, The Millennium Trilogy) such hot property. The title serves as agent provocateur for the action that follows: a fractured and wilful deconstruction of group dynamics, of the pressures and “victims” of the social collective.

RED has an interesting backstory: rather than being an adaptation of a novel, or the umpteenth reworking of a Hollywood formula, it has been adapted from the graphic novel of the same title by Warren Ellis, illustrated by Cully Hamner and published by the DC Comics stable. And its origins show in its slick editing, sly humour and original take on what is, let’s face it, hardly a fresh format. But where else can you see an action movie in which the youngest participant is well into his fifties?

Verbatim drama, long established in theatre, has rarely been used in film. But director Clio Barnard uses the device to magnificent, and sometimes deliberately disjointing, effect in The Arbor, to tell the story of Bradford playwright Andrea Dunbar, who wrote The Arbor and Rita, Sue and Bob Too (made into a film in 1986) before she died at the age of 29 in 1990.

A journalist’s car breaks down on a mountain road in the middle of nowhere. He’s towed to a tiny hamlet, where small stone houses are overshadowed by huge painted images of the bearded Ayatollah. A woman wearing a black chador insists on speaking to him. "There are things in this village you do not know about," she hisses. Melodramatic, yes, but this powerful, disturbing film is based on a real event in mid-Eighties Iran, which makes it easier - or perhaps harder - to bear.

Success has many parents, the old saying goes. And that’s certainly the case in David Fincher’s new film, an enthralling dissection of one of the great success stories of our age. When Harvard undergraduate Mark Zuckerberg devised a putative version of the Facebook website in October 2003, he can not have imagined it would spawn a global phenomenon with more than half a billion users. Nor could he have predicted it would result in a sea of litigation that would pit him and his company against both aggrieved former friends and slighted foes alike.

Howard Marks was a pothead Errol Flynn, living a life of remarkable escapades and hair's-breadth escapes. A Welsh working-class Oxford graduate in nuclear physics and philosophy, he’d be fascinating company even if he wasn’t once the world’s most successful dope smuggler, and an associate of the IRA, the CIA, the Mob and MI6. His autobiography, Mr Nice, has let Marks earn a living reminiscing about it ever since. But Bernard Rose’s adaptation casts inadvertent doubt on such cult heroism. Marks’s life here seems somehow inconsequential.

The most surreal scene in this searing, adrenaline rush of a documentary about a US platoon in Afghanistan is the sight of three soldiers dancing madly in their bunker to "Touch Me, I Want to Feel Your Body" on an iPod.
