The latest film from acclaimed Japanese director Hirokazu Kore-eda (Still Walking) tells the story of two young brothers who are separated when their parents divorce and who attempt to bring their family together again. While its prosaic subject matter might sound far from must-view material, I Wish is absolutely a film to savour, one whose considerable folksy charm, humour and authentic spirit will take you hurtling back to your own childhood adventures.

It’s not often that a performance’s technological properties leaves you simply slack-jawed. Robert Wilson’s very long Swedish-language version of Strindberg’s A Dream Play did – at the same venue, though this time in 2001 – when the surtitle machines broke down (the audience gave an audible gasp of horror and then settled to its collective fate), but that was for altogether different reasons. Compared to what Ryoji Ikeda and his team are capable of, even the beautiful crispness of Kraftwerk’s stage shows fade into the realm of the bland.

“Improvisation? That?” whispered a Japanese lady to her friend at the end of the afternoon concert. She was making a good point. Half the performers in this programmed jam were glued to their scores. It was the low point of a mixed day at the Barbican Centre that began with a very enticing premise of offering to immerse us in the “Sounds from Japan”. We barely dipped our toe. The problem wasn’t simply the variability of the music; it was also the laziness of the curatorial thinking.

There is never a dull moment in this three-hour historical epic, even if it is not always clear what is going on. Directed by Gregory Doran, of the RSC, Anjin follows the 17th-century story of William Adams, the first Englishman to land in Japan. The production has lines in English and Japanese, with surtitles above the stage and on either side, but it is sometimes difficult to read the words and watch the characters, especially for audience members in the middle of the stalls.

The news that Studio Ghibli were making a computer game was met with resounding excitement when it was announced way back in 2010. Right from the off the possibility of being able to adventure through the dark and mystical worlds of Spirited Away or Princess Mononoke was tempered with the fear that we might end up skipping through the candyfloss Disney/Ghibli worlds of Ponyo or Arrietty instead. Unfortunately with Ni No Kuni, it’s clear to see which school of Ghibli has won out.

David Bowie already had a bit of previous with Christmas, of course, after pa-rum-pa-pumpum-ing through the tinsel with Bing back in 1977. He plays a very different kind of drummer boy in Nagisa Oshima’s uneven but oddly haunting 1983 film, in which he stars alongside Tom Conti (last seen in Miranda, of all things) and Ryuichi Sakamoto.

Joe Muggs writes: “KanZeOn is one of my favourite films – not just music films, but in any genre – of the past year. Not quite documentary, not quite art film, not quite music video, it's a slow, abstract audiovisual love poem to Japan and its relationship to sound and music.

Though this 1966 comedy was a light and fluffy thing, it was gazed upon benignly by the critics, mostly because it was a late vehicle for the well-oiled Cary Grant charm machine. It proved to be his last film, in fact. Others viewed it equally fondly because it contained scenes of Grant in his boxer shorts, a challenge he tackled with panache despite his 62 years.

With Euro 2012 about to end and the Olympics looming, we'll be hearing an awful lot of national anthems over the next couple of months. Don't we all agree that the majority of them are inadequate - often being turgid tunes with no reference to the culture of the countries involved?  Isn't it about time we had some alternatives? Here are a few suggestions.
