Any consideration of Iranian director Jafar Panahi’s Closed Curtain will inevitably be through the prism of how it was made, and the director’s current position in his native country. It’s his second work, after This Is Not a Film from 2011, to be made despite the 2010 prohibition from the Iranian authorities that (along with a range of other curtailments of his freedom) the director should not engage in cinema for a period of 20 years.

Fair exchange? German humour, perhaps? We send Her Maj off to the Fatherland for a State Visit, and the Embassy of the Federal Republic in London reciprocates by bringing us the popular singing phenomenon – “national institution”, as he was described in last night's introductory speech – Max Raabe, for an early celebration of 25 years of German reunification.

There is ice at the heart of German director’s Dietrich Brueggemann’s Stations of the Cross (Kreuzweg). Winner of this year’s Berlinale Silver Bear for best script – the director wrote the film in collaboration with his sister Anna – it’s a chilling look into the psychology of extreme religion, in this case very traditional Catholicism, set in small town Germany. Formally impressive, it’s unsparing in its point of view in telling a tragic tale.

Falling in love for the first time is one of the standard tropes of the movies. Brazilian director Daniel Ribeiro gives it a new twist by making the teenage hero of his The Way He Looks (Hoje Eu Quero Voltar Sozinho) blind, and realising in the course of the film that he’s gay.

We see the harshness of everyday life in Danis Tanović’s An Episode in the Life of an Iron Picker first in its snowy, subsistence landscapes, as hero Nazif goes out to the forest to bring in whatever wood he can find to keep the family home warm. But by the end of the film, which took the Jury Grand Prix at last year’s Berlinale, we have seen, much more chillingly, the harshness of human behaviour.

He cuts a dash, that man Cave. Very tall, gangly, with his idiosyncratic snub nose and upside-down-U-shaped hair, the Australian is a one-off. His growly music isn’t always easy to like. In his fury days with the Birthday Party and the Bad Seeds, he was a post-punk rock poet. He has, of course, oceans of fans. It goes without saying that they will be a-quiver at 20,000 Days on Earth (20,000 was the number of mortal days Cave had notched up three years ago when this documentary started: he’s now 57).

The Chinese thriller Black Coal, Thin Ice by director Diao Yinan won the Golden Bear at the closing ceremony of the Berlinale last night, as well as picking up the best actor prize for its star Liao Fan.

It was a night for Asian cinema in general, with the best actress award given to Japan’s Haru Kuroki, playing in veteran director Yoji Yamada’s The Little House, while Chinese cinematographer Zeng Jian came away with the Silver Bear for outstanding contribution in the technical categories for his work on Lou Ye’s Blind Massage.

You couldn’t imagine The Kidnapping of Michel Houellebecq (****) coming out of anywhere except France. Three years ago the enfant terrible of French literature vanished for some days from a book tour, giving rise to rumours as extreme as that he had been kidnapped by Al-Qaida. Guillaume Nicloux’s wry and eccentric comedy, playing in Berlinale’s Forum programme, recycles that legend, only in his film Houellebecq is vanished to a gypsy compound outside Paris where he’s held in circumstances that couldn’t be friendlier.

Back in the 1950s the Zurich underground club Der Kreis was a rare beacon of tolerance of homosexuality in Europe. Fitting then that Swiss director Stefan Haupt’s drama-documentary of the same name, The Circle (****), won this year’s Teddy award at the Berlinale, in the documentary category: the Teddies have been going since 1987, making them no less of a pioneer in the gay world, their brief to acknowledge and support LGBT cinema from around the world.

Not the least remarkable thing about Richard Linklater's Boyhood is its being shot over a decade – that’s probably a first in film history. And it’s more than a sociological experiment, portraying in vibrant contemporary detail and a lot of observational fun the growing-up in Texas of a little boy, Mason, which will surely have an extraordinary impact on the life of the actor, Ellar Coltrane, who played him. It must be a bit like having a red carpet rolled out for you before you know the meaning of or have ever uttered the words “acting”, “award” and “celebrity”.
