Verbatim theatre has been the flavour of political theatre for the past two decades, and no theatre has done more to promote this style of public witnessing than the Tricycle in Kilburn, north London. Its artistic director, Nicolas Kent, has created a special style of verbatim drama called tribunal theatre, where the results of long-running public inquiries or trials are edited into an evening’s viewing. His latest venture, Tactical Questioning: Scenes from the Baha Mousa Inquiry, which opened last night, illustrates the pros and cons of this type of infotainment.

Peter Mullan’s incendiary and long-overdue third feature is an unflinching, often hilarious look at a teenager’s inexorable descent into delinquency. NEDS (or Non-Educated Delinquents) begins in Glasgow in 1972, immersed in a rosy haze of promise as the chubby-cheeked, saucer-eyed John McGill graduates from primary school. Moments later he’s being threatened with a beating to end all beatings by a malevolent peer.

Hanna begins with a bang, and there will be those for whom the excitement never lets up – especially if you like your action movies all but bereft of chat. The young assassin of the title scarcely needs words when her days are given over to taking careful aim. Sure, her father makes a case for the need for language, but determination and a good eye take the feral Hanna infinitely further than pleasantries such as “Hello”.

Mark O’Rowe is one of Ireland’s leading contemporary playwrights, and Terminus was first produced in 2007 by the Abbey Theatre in Dublin. It transferred to the Edinburgh Fringe in 2008 and is now being revived by the Abbey in an international tour. His play charts another ordinary night in Dublin city, but as this captivating triptych unfolds the events his characters - simply named A, B and C - describe are anything but. A man and two women deliver a series of overlapping monologues about love, sex, loss, regret and acts of shocking violence, but also of angels transporting souls to the afterlife, a demon made of worms and a pact made with the devil. The language - sparkling, funny and heightened - is poetic and fantastical, Molière meets magic realism.

Route Irish isn’t the St Patrick's Day parade along Fifth Avenue in New York, but the “most dangerous road in the world”, from Baghdad airport to the relative safety of the heavily fortified Green Zone.

This debut feature by writer/director Thomas Ikimi was shot in 22 days on an infinitesimal budget, and while it's easy to point out some obvious flaws, it's far more constructive to look at what Ikimi has achieved. Chiefly, he wrote a script intriguing enough to lure Idris Elba on board, and he not only agreed to play the central role of Malcolm Gray, but additionally gave the project a hefty professional shove.

Recently, some British playwrights have gone back to school, and found that it feels very much like a war zone. All the old tensions between teachers and pupils have escalated into open conflict: knives are drawn, punches thrown and arguments are settled by fights. Likewise, the language is disrespectful at best, and always expletive-heavy. Vivienne Franzmann’s new play, which visits London after opening in Manchester last month, frankly refers to a war zone in its title, and its action is scarcely less antagonistic.

The animals 17-year-old Josh Cody has to survive are his own criminal family. The Codys are hardly the Corleones. Led by sweetly smiling, grandmotherly matriarch Smurf (Jacki Weaver) as they fume and feud in Melbourne’s suburbs, this motley gang of five’s only outstanding quality is their ruthlessness. Deposited with them when his mum overdoses on drugs, the shy teenager navigates between armed robber Uncle Pope (Ben Mendelsohn) and wired drug dealer Uncle Craig (Sullivan Stapleton).

Based on a novel by Kanae Minato, Tetsuya Nakashima’s provocative, serenely sinister thriller is fuelled by the murderous desire of its teens and the righteous anger of their teacher. Best known for the inebriated mania of Kamikaze Girls and Memories of Matsuko, in Confessions Nakashima trades his outrageous rainbow hues for a distinctly funereal aesthetic. It’s as if a dark veil has been drawn across his signature style, with the film bowed in sombre recognition of its troubling subject matter.

Actor/director Peter Mullan describes NEDS, his third film as director (after Orphans and The Magdalene Sisters), as “personal but not autobiographical”, although it undoubtedly draws heavily on his working-class upbringing in 1970s Glasgow. He was, like his lead character John McGill, the academically gifted younger brother of a local hard man, determined to do well at school and escape the violent life he saw around him.
