So overt it’s covert. That’s how the famous detective explains away the crassness of his disguises. In this newest instalment of the latest cinematic incarnation of the Holmesian myth, the detective rummages through the dressing-up box for silly beards, false gnashers, stupid specs. This Holmes even wears a type of babygrow whose patterning comically blends into the decor. As with Sherlock Holmes, so with Sherlock Holmes: A Game of Shadows. This is another film by Guy Ritchie disguised as a detective story by Arthur Conan Doyle. You couldn’t ever mistake it for the real thing.

The decontamination squad scraped the remains of 38-year-old ex-City professional Joyce Vincent from her seat, in front of a TV which had flickered unseen for three years. They took her wrapped Christmas presents too, and left unsolvable mysteries. How did she die? And how does someone become so alone that they’re left in a north-London flat above a busy shopping centre till their body melts into it?

There's quite a bit to admire in DR Hood's debut feature. There's the cast for a start, headed by nascent superstar  Benedict Cumberbatch alongside Brit-dram It-girl Claire Foy. Beguiling, too, is the piece's setting in the fenlands of East Anglia (quite near Mildenhall airbase, one would guess, judging by the eerie shots of American aircraft drifting overhead).

It’s got Daniel Auteuil striding moodily (yet approachably) through the Provençal countryside so it must be Pagnol, right? Up to a point. He is best known to us as the author of Jean de Florette and Manon des sources. On paper, this is vintage Marcel Pagnol – a remake of the writer-film-maker’s 1940 film La fille du puisatier, faithful down to large chunks of dialogue – but on screen this is a rather different creature, and it’s clear that there’s a new eye behind the lens. That eye belongs to none other than Auteuil himself.

“This story is not my child, or my godchild. It is not a work of fiction. It is a diary of suffering,” a title says at the beginning of Raúl Ruiz’s magnificent Mysteries of Lisbon. A sombrely beautiful 19th-century costume drama spanning decades and continents and featuring tortured lovers, deathbed confessors, abandoned sons, femmes fatales, sniping aristocrats, Napoleonic-era firing squads and duellists, Ruiz’s labyrinthine, flashback-laden movie makes for a peculiarly heady blend of Romantic epic-cum-soap-opera and Modernist disquisition on narrative self-reflexivity.

Recorded music has a lot to answer for. Until its arrival, most people made their own music – at home, using whatever resources were to hand. If you were lucky, you might have owned a piano. The less well-off might have had access to a ukulele. Tony Coleman and Margaret Meagher’s enchanting, lo-fi documentary stakes a bold claim for the ukulele’s pivotal role in 20th-century music history.

The Shrek series is resurrected once again for this amiable, action-packed - if less than purr-fect - 3D spin-off, featuring everyone’s favourite diminutive swashbuckler. If the franchise was a feline it would be running out of lives (and good will) fast, but fortunately this prequel leaves the magical land of Far Far Away, well, far, far away - instead setting its story amidst the red dust and diabolical double-crossing of a spaghetti western.

Another Earth begins, like many more reliable but less ambitious films, with a life-changing event. A young astrophysicist is involved in a collision. Climbing unharmed from her vehicle, she finds a woman and child dead by her hand. Four years later she emerges from prison and attempts to make contact with her surviving victim, who turns out to be an eminent composer. Her nerve fails, but still she finds herself worming her path into his world.

Idiotically buried by a release which sees it appearing on just one screen nationally, Kenneth Lonergan’s triumphant follow-up to his Oscar-nominated debut You Can Count on Me (2000) is, without a scintilla of a doubt, one of the finest films of 2011. Rich, resonant and with a meticulous approach to characterisation, it captivates, convinces and challenges.

In his home country, the release of the latest film by Nanni Moretti is always an event, all the more so in the case of We Have a Pope – a bittersweet psychological comedy with tinges of tragedy about a cardinal who is elected to the throne of St Peter, has a panic attack, and does a runner leaving the Catholic Church in crisis and the world media with a bonzer news story. It arrives a full five years after his last outing, Il caimano.
