Iranian cinema is about to get a whole lot more interesting with Asghar Farhadi’s “Nader & Simin: A separation,” which in theory should be shown in limited release in about two months in the U.S.

Shot in semi-clandestinity in Tehran, it tells the tale of a couple, on the verge of separation, who are ripped apart by a parent’s Alzheimer’s disease and a caretaker hired to help him make it through the debilitating disease. Class differences and the slow disintegration of the couple’s life seem to be the order of the day in this narrative.

Farhadi won the Silver Bear for best director two years ago for his film “About Elly.” “Nader and Simin” was widely seen as a shoo-in for the Golden Bear, both for its outstanding quality in a year of insipid competition fare and the spotlight thrown on Iranian cinema by incarcerated director Jafar Panahi, for whom the festival kept an open jury seat for the duration of the festival.

The international jury of the 61st Berlin Film Festival, presided over by actress Isabella Rossellini, jointly awarded the Silver Bears for acting to the ensemble cast of “Nader and Simin.” Among the six actors and actresses who shared the two statues was the director’s teenage daughter, Sarina Farhadi. In the film, she plays the daughter of a feuding couple who is faced with choices of loyalty and ethics. The other honorees were Sareh Bayat, Leila Hatami, Peyman Moadi, Ali Asghar Shahbazi and Babak Karimi.

The Grand Jury Prix went to Bela Tarr’s sparse and minimalist “The Turin Horse,” about a coachman and his daughter going about their daily routine while an apocalyptic threat looms. The film has divided critics. Personally, I found the film’s purity and visual beauty masterful. But to be honest, the sparsely of dialogue, repetition of mundane actions and slowness make for an outstandingly difficult film to sit through (and I’m saying that as someone who watched all 7 ½ hours of “Satantango” in rapt concentration).

The separation itself is somewhat of a MacGuffin and does little more than set all the pieces in motion. The most we hear about marital disputes is in the tense opening scene, a single static shot that shows the spouses pleading their cases, from the perspective of the marriage clerk’s desk. Simin explains that she wants to take their eleven-year-old daughter to study and live abroad. Nader insists on staying behind to tend to his Alzheimer-afflicted father.
