Jean-Luc Godard has lived in self-exile for most of his film-making life, a now 80-year-old enfant terrible. After the seismic ruptures to film grammar in his self-aware, playful Sixties work, he largely abandoned narrative and popularity at the start of the Seventies.

Great idea. Geeky Hasidic kid from Brooklyn's claustrophobic Jewish community finds his attention wandering during his rabbinical studies, and falls under the raffish spell of the older and wilder Yosef Zimmerman. He finds the slope is slippery indeed, and with head-spinning speed he's enmeshed in a transatlantic drug-mule racket. He's making big piles of wedge, but losing his immortal soul in the process.

At the end of last week it was reported that a Connecticut cinema, besieged with requests for refunds, had posted up a sign warning punters that The Tree of Life “does not follow a traditional, linear narrative approach to storytelling”. And so what? Terrence Malick’s Palme d’Or winner is certainly elliptical and impressionistic, but it’s also spellbinding, and as lofty and luminous as the stars in the sky. Above all, it’s a film which is buoyed – and which sometimes threatens to be sunk - by its own formidable ambition.

If you had a quid for every time a nerdy character in a contemporary comedy made reference to Star Wars, in particular to the gnomic wisdomous utterances of Yoda, you’d be richer. Maybe not as rich as George Lucas. But it happens. It happens a lot. A country short on mythology sources its gods and heroes in kiddie lit and stores them in the toy box. Over here we’ve got Homer.

Do you know where your teenagers are? If they're smart, they'll be somewhere watching Trust, the sophomore directorial effort from actor David Schwimmer that turns out to be as deftly compelling as it is unnerving.

The capture and arraignment of Ratko Mladic has brought atrocities committed in Bosnia back onto the front page. As Martin Bell used to argue, the Bosnian war struggled to hold the world’s attention even when it was going on. Two much more major conflicts, in which we have been doing the bombing rather than the peacekeeping, have since sent Bosnia plummeting down the squash ladder of important contemporary conflicts.

What is it with Hollywood and education? Hot on the heels (shamelessly come-hither pumps, in fact) of Cameron Diaz in the lamentable Bad Teacher, we now get Julia Roberts as a disaffected babe who, we're told, is a teacher even though she spends precious little time in actor-director Tom Hanks's new film doing anything of the sort. Still, at least Roberts's unquenchable radiance lends Larry Crowne some measure of class; otherwise, here's another movie that merits detention for failing to make more than a passing detour in the direction of real life.

Some directors are just grateful that their movies get funded and released, but Robert Redford has loftier aspirations. Scornful of the routine popcorn-spattered multiplex-filler, he thinks we should be prodded to improve our lot by learning the lessons of history, and says he wants to tell stories about "ordinary people that are affected by larger forces out of their control". This lofty blueprint has brought us Bob's latest behind-the-camera odyssey, The Conspirator.

When the infantilisation of Hollywood started in 1977 with Star Wars, as a 10-year-old I was all in favour. The hugely successful Transformers franchise based on a series of clever 1980s toys - they’re a car; some Origami-style fiddling later, they’re a robot! - probably isn’t where that trend bottoms out. Michael Bay, the most bombastic, critically derided and commercially unsinkable director around, has as the title suggests gone prog rock for this third film, pumping up the Transformers “mythos”, and dragging it out to triple-album, 154-minute length.

Asghar Farhadi’s new film unostentatiously suggests that Iran has many of the same things we have: cars, cash machines, schools, sex, divorce, Alzheimer’s. It doesn’t, we gather, have modern law. Before howls of protest erupt over so banal and Western-slanted a generalisation, I stress that this is the film’s contention: the madness of law the film proposes is not necessarily fact.
