Fans will relish the chance to see Katy's rainbow-tastic live shows magically enhanced by 3D technology. Those indifferent to her will leave as perplexed about Perry's superstardom as they were before.

The final act has an inevitable wavering patch when the film is obliged to tut-tut about the shallowness of the stripping, drinking, bantering, carousing and whooping it has previously enjoyed, but this is terrific entertainment with a sideline in wry melancholia and testosterone-fuelled philosophy. Have 20 dollars.

Part road trip, part revenge movie, this is a tentative tale of a man who's not going to take it anymore, sharp on the fallibility of human foibles and sometimes stingingly funny, too.

Enjoyably satirical and occasionally insightful, it's betrayed by some lazy stereotyping.

A little pretentious maybe, but then you've got to wonder at a woman who could sit motionless in a wooden chair, eight hours a day for three months.

Graced with great performances from Garfield and Stone, The Amazing Spider-Man is a rare comic-book flick that is better at examining relationships than superheroism. If it doesn't approach the current benchmark of Avengers Assemble, it still delivers a different enough, enjoyable origin story to live comfortably alongside the Raimi era.

It benefits from a supernaturally engaging cast, but this treads too closely to the rom-com model to feel as smart or moving as Westfeldt's previous best.

Less confrontational than most Solondz movies, in that it refrains from violence or kink, but still unsettling and affecting.

The grave tone makes it stiff and leaden, the digi-saturated look is a turn-off. Damnable and disordered.

Despite one or two nice moments and the naturalistic tone, it's all a bit of a slog.

Another solid hit from Planet Apatow - charming, funny and remarkably in tune with real life.

Like every one of its songs, it makes a lot of noise about nothing much and cockily straddles awfulness and greatness. It's enormously entertaining nonsense.

An ambitious thriller from Pawlikowski assisted by excellent performances from Hawke, Kulig and Scott Thomas.

Unsparing in its portrayal of the seedier side of French society, only Polisse's loose focus keeps it from matching The Class for emotional punch. It's still a worthy companion piece to TV police procedurals like Spiral.

Quietly compelling, the cerebral slice of social realism is well worth hunting down.

Even with a strong cast to gild its endless chambers and salons, there's barely a spark of soul to fuel its story. Pattinson is no Malkovich either.

Buffeted by a lack of suspense, threadbare characters, and a very poor script, the stunning visuals, gloopy madness, and sterling Fassbenderiness can't prevent Prometheus feeling like Alien's poor relation.

A charming, visually sparkling Parisian fantasy with a dark edge.

A strong visual style tussles with flaccid storytelling in this ambitious retelling of Grimm. It won't exactly have Walt Disney spinning in his secret ice chamber, but you may wish they spent more time worrying about what exactly the film is than who it's for.

Talented Norwegian Joachim Trier - distant cousin to the better-known (and Danish) Lars - delivers a wonderful, melancholy character piece that's funny and tender, and as fresh as a breath of Oslo sea air.

As funny, bittersweet and as distinct as you'd expect from Wes Anderson, a director who helps you know you are not alone. Terrific performances from sprogs to stars and a lovely sense of the sorrow and joy of growing up.

Despite some good moments, Agents J, O and K are missing an E.

Remember your first time with Hard Boiled? Die Hard? This is how it's done - a clean, hard, constant hit of adrenalin. If it's not the best action movie of the year, we'll eat a fridge.

Formulaic, yet scrappy, and extremely funny in fits and starts, General Aladeen is the first of Cohen comic creations to get a better vehicle than it probably deserves.

A word of warning: this is not the knockabout comedy the trailer suggests. Instead, it cleaves closer to what you expect from Burton: darkness, quirk and Johnny Depp on great form. A step up, then, from Alice In Wonderland and Charlie And The Chocolate Factory, but not tip-top Tim.

With so many films adapted from novels, it's nice to see cinema paying homage to unheralded greats of literature like Sebald. While this one often struggles to do justice to his sense of grandeur and poetry, it'll be manna for fans of the German's work.

There's undoubtedly comedy mileage in an irreverent sending up of the Signs/Magnolia school of everything-is-connected philosophy. Despite the calibre of the cast, the Duplass brothers mostly fail to find it.

The pair muster some chemistry but it's the big musical moments - including a gusto-packed Soft Cell riff - that impress most. Sadly, the pair's romance is predictable and the plot unfolds with all the freshness of a two day old fish supper.
