"When you are in the middle of a story it isn't a story at all, but only a confusion," writes Margaret Atwood in Alias Grace, and it's these words that open Stories We Tell, fellow Canadian Sarah Polley's fourth film. This is Polley's first documentary - although it hardly does it justice to call it that. It starts by telling a family story - a story Polley herself is indeed smack bang in the middle of - which requires her to be both director and detective, and presents her with the seemingly impossible task of distancing herself.

The most interesting thing about this movie is what it says about the changing relationship between film and television. It's becoming commonplace to hear actors, writers and directors claiming that TV is now the place to be for powerful drama with narrative scope and rounded characters.

Italian documentarist Andrea Sigre’s first feature captures with great tenderness the delicate balance of friendship that grows up between two characters who live as relative outsiders in their community.

Before Midnight is the third part in Richard Linklater's romantic series starring Ethan Hawke and Julie Delpy as star-crossed lovers Jesse and Celine. It's a sequence of films that began in 1995 with Before Sunrise (pictured below right), where the two spent a night wandering Vienna, falling in love. That was followed nine years later by 2004's equally delightful and even more insightful Before Sunset, which followed them on an afternoon rendezvous through Paris.

The story goes that Ben Affleck was in the running to direct the latest Superman "reboot", but decided against. "A lesson I've learned is not to look at movies based on budget," he said. "Story is what's important."

Ever wondered what Buffy the Vampire Slayer and Angel creator, not to mention superhero movie A-lister Josh Whedon, does during his down time? Well, apparently he gets his pals together to have a go at the Bard. And by way of proof, along comes Whedon's film adaptation of Much Ado About Nothing, which plays like nothing so much as a home movie in Elizabethan tongue.

The likelihood of leaving a screening of PARADISE: Love without feeling either queasy or at least a little off balance is low. This realist-styled portrayal of middle-aged Teresa’s excursion to Kenya to seek intimacy and, inevitably, sex is awkward viewing. Some scenes are so uncomfortable to watch that their imprint will be permanent. PARADISE: Love is made all the more an assault on perceptions of acceptability by being entirely unjudgemental. Reactions are entirely up to the viewer. Director Ulrich Seidl offers no helping hand.

People genuinely care about words in Josh Boone's directing debut, Stuck in Love, and that's as might be expected from a film that went by the name of Writers when it premiered in Toronto last autumn. So the first thing to be said is that this likable American indie is nicely written (a rarity in itself these days), notwithstanding an ending that trades heavily on the inevitable uplift that is the Hollywood norm even in such low-budget climes.

The first image in Aguirre, Wrath of God (1972) shows clusters of mist hovering over the darkened Andes. Mirroring the implacability of the terrain, Popol Vuh’s synth score evokes a celestial choir hymning the mountains' numinous might, worried though the music is by faint high-pitched vibrations. In a short series of downward tilt shots, the camera – unseen, but a “felt” presence throughout, as drops of moisture on the lens later testify – picks out insect-like figures tentatively making their way in single file down a narrow path hundreds of feet above the Amazon.

The party's over in more senses than one in Behind the Candelabra, the Steven Soderbergh film dedicated to the proposition that all that glitters is most definitely not gold. It charts the downward spiral of the relationship between the American king of piano-playing glitz, Liberace, and his onetime "chauffeur" and companion, Scott Thorson.
