Two members of Thet Sambath’s immediate family were murdered during the Khmer Rouge’s time in power in Cambodia. His father was killed when he objected to the organisation's seizure of his property, while his mother was then forced into marriage with a Khmer Rouge militia. She died soon after following complications in childbirth. His older brother, who had witnessed the brutal murder of his father, was also later executed. Enemies of the People, a documentary made with Rob Lemkin, is Sambath's illuminating, admirably restrained insight into a brutal regime.

Sofia Coppola proved, with Lost in Translation from seven years ago, that there’s hardly a better location for showing the nuances of emotional dysfunction than the anonymity of an international hotel. No surprise then that much of her new film Somewhere, winner of the Golden Lion award at the Venice Film Festival, is set in the characterless corridors and rooms of the celebrity hang-out Chateau Marmont in Los Angeles, though her investigation here of a central father-daughter relationship delivers a stronger emotional reflection than in the earlier film.

Americans apparently revere their great racehorses, especially if they carry their weight in socio-political resonance - or its absence. Thus, the $58 million-grossing Secretariat, about the powerful red chestnut with the inordinately huge heart whose bid to win the 1973 US Triple Crown supposedly diverted attention from Watergate and Vietnam, arrived comparatively quickly after Seabiscuit, the 2003 Best Picture Oscar nominee and second film about the undersized knobbly-kneed bay who thrilled Americans during the Great Depression.

I've been to a fair few spoken-word events in my time, and as a rule the more upmarket they are, the worse they tend to get. The bigger the celebrity or cult cachet of an author, the more likely they are to attract a crowd that turn up mainly to be seen basking in their reflected literary glory – pulling theatrical "concentration faces" during the reading then shooting to the bar to network wildly as if the writer were mere sideshow.

Easier with Practice is a film about phone sex based on a short story that appeared in GQ magazine. It’s enough to make any right-thinking filmgoer not in the Will Ferrell/Chuck Palahniuk/American Pie core demographic head for another screen – any other screen.

As Ozzy Osbourne puts it, “He’s just Lemmy. You just take him or you fucking don’t, and he doesn’t give a flying shit whether you do or not.” It’s this irreducible Lemmyness of Lemmy which lies at the core of the gnarled heavy metaller’s mystique. Beyond fashion, as ageless as a rock’n’roll Flying Dutchman and with a constitution seemingly forged from buffalo hide and wrought iron, Ian Fraser “Lemmy” Kilmister is surrounded by his own private myth-bubble wherever he goes.

With a script co-written by the Palestinian journalist Rula Jebreal, based on her 2004 book of the same title, Miral follows the interconnected lives of four women caught up in the Arab-Israeli conflict. It’s a sprawling, epic affair, directed by the New York painter turned film-maker Julian Schnabel.

Towards the end of Of Gods and Men, nine monks sit around a table and, following the protocol of a well-known biblical meal, partake of bread and wine (and, these being French monks, cheese). As they eat and drink they listen on a cassette to the ardent swirls of Swan Lake while the camera fixes on craggy faces caught in blissful, intensely moving transports of faith. It may not sound like much of a cinematic climax. But at least as much as any film arising from the so-called war on terror, Of Gods and Men demands to be seen.

They say that crime doesn’t pay, yet the criminal underworld has certainly been good to William Monahan. His slick screenplay for 2006’s Boston-Irish gangster flick The Departed won him an Oscar, and now London Boulevard – a mean-streets-of-south-London, Lock, Stock knock-off, casual knifing of a film – sees him make the upgrade to the coveted writer-director credit.

It is not uncommon for opportunistic film-makers to put together a flashy promo in the hope it will attract enough investors to turn it into a full-length feature. When Robert Rodriguez made the Machete trailer for 2007 double-bill Grindhouse, though – an all-action spoof featuring striking bit-part actor Danny Trejo as its titular knife-wielding protagonist – he had no intention of taking this parodic in-joke any further.
