The onset of puberty is difficult, and especially so for girls in art house films. Marta is 12 and has been away from Italy for 10 years. In the days after returning with her mother and sister, she contends with being prepared for her first communion and her changing body. Quietly, as if not there, Marta observes the hypocrisy of adults. Dog-tired from working in a bakery, her mother is forced into the background.

This weekend Robert Redford and his Sundance Institute are bringing a sort of taster version of the world’s leading showcase for independent (non-studio) English-language films to London. No one’s going to mistake Greenwich’s O2 Centre for an upscale skiing resort in the Rockies, home of the famed Sundance Film Festival which is held in January, but if Sundance London lacks the funky screening venues and bars of Park City, Utah, it also doesn’t require standing in line in the snow and freezing cold.

Unlike the New Seekers, Whit Stillman does not want to teach the world to sing. He does, however, want to teach it to dance, specifically to dance the Sambola (or, to give it its full name, Sambola! The New International Dance Craze). Instructions and a demonstration accompany the final credits of his new film, Damsels in Distress.

 It’s not so very rare for actors to be given a shot at directing their own film. It happens slightly less often that they find financial backing to work on their own script. What makes Breathing, which opened this week in the UK, such a collector’s item is that it is so very accomplished.

One of the most refreshing aspects of current Latin American cinema, most evident in Argentina, Uruguay and Chile, is a particular brand of off-beat romantic comedy – one with echoes of the literate and quirky US independents of the Eighties and Nineties, of Hartley, Jarmusch and Tom DiCillo, but laced with melancholy and shards of realism that are specifically Latin.

Ken Russell fans within reach of the capital will have a surfeit of goodies from tomorrow as London films clubs in the Scala Forever network open a tribute season devoted to the iconic British film director, who died last November.

The Chemical Brothers have long had one of the most vital shows around. It’s a visual spectacular that can only be likened to peak-time Pink Floyd or Jean-Michel Jarre, yet precision-tooled, without the bombast of those acts. Their long-term visual designer, Adam Smith, is mostly responsible and now he’s shot a concert film of the electronic duo’s appearance at the Fuji Rock Festival in Japan last year. Smith has directed a few bits and bobs before, notably the BBC adaptation of Little Dorrit, and he’s the perfect choice to take the Chemical Brothers experience into the cinema.

Although Lars von Trier’s latest boasts a few mainstream stars (amonst them, Kirsten Dunst, Charlotte Gainsbourg and Kiefer Sutherland) and the director himself has described the film as having not only having a Hollywood aesthetic but also - horror of horrors - a happy ending, everything is relative.

Margin Call, a smart, taut and brutally frank portrait of the money game, asks a lot of its audience. A movie about traders as, if not quite good guys, then at least rounded guys? It’s not a trick Oliver Stone ever managed to pull off, and he tried twice. Refusing to deal in the Hollywood placebos of idealism and redemption, this is not a product that the big studios would have gone anywhere near.

While the rest of the country has been busy discussing the knitwear of Denmark’s answer to DCI Jane Tennison, I found myself bereft of anyone to share my unbridled enthusiasm for this Australian adaptation of Christos Tsiolkas’s novel The Slap. Even at the virtual watercooler of Facebook, only one person gave me a thumbs up when I wrote a paragraph on its excellence. Why a fairly generic murder procedural should inspire such obsessive devotion while a completely original and gripping family drama is relatively ignored is something of a mystery.
