A slow tracking shot over the gassed corpses of soldiers, their masks having failed the ecstasy of fumbling, opens The Guardians. This French art house film would perhaps have been better served by the English title The Caretakers; it's closer to the original French meaning and would have made it less likely to be confused with a superhero movie.

This should have been the third much-anticipated Prom of the City of Birmingham Symphony Orchestra's inspiring communicator-in-chief Mirga Gražinytė-Tyla. She's now on maternity leave. So those of us who hadn't experienced Ludovic Morlot live before had a chance to witness what a splendid moulder and shaper he is, here in a skilfully co-ordinated all-French programme.

It was Simon Rattle’s first visit to the Edinburgh International Festival for – well, really quite a few years. And the first of his two concerts with the London Symphony Orchestra drew, perhaps predictably, a capacity crowd in the Usher Hall, for what was in fact quite an odd, uncompromising programme – if one that ultimately delivered magnificently.

So much of Japan can be lost in translation, and yet the West is fascinated by a culture that articulates the possibilities of belief and being in such a different mode than our own.

“When you were our age, how did you imagine your life? What did you hope for?” It is a video of a classroom south-east of the Périphérique separating Paris from the working-class suburbs. The students are mostly girls between fifteen and sixteen and they wear make-up, jewellery, low-cut tops – we understand they’re sexy, confident, cool. Several are African, North African, Caribbean.

What’s that? Joan Crawford had no sense of humour? Well, take a look at It's A Great Feeling. It’s a pretty bizarre (and pretty bad) 1949 musical with Jack Carson and Dennis Morgan playing themselves running round the Warner Brothers lot attempting to make a picture.

"When the new god approaches, we surrender, struck dumb". Especially if, for the singer of those words, popular entertainer Zerbinetta, the “new god” takes the shape of same-sex love.

There's surprising and then there's The Lehman Trilogy, the National Theatre premiere in which a long-established director surprises his audience and, in the process, surpasses himself. The talent in question is Sam Mendes, who a quarter-century or more into his career has never delivered up the kind of sustained, smart, ceaselessly inventive minimalism on view here.

You come to Christopher Ian Smith’s New Town Utopia expecting a damning indictment of post-war British planning. But while there are melancholy moments, this is mostly an upbeat documentary. Smith manages, without the use of CGI, to make the much-maligned Essex new town of Basildon look uncommonly attractive. The spiritual home of Essex man, this solidly Conservative town isn’t what you’d expect.
