With his debut as a writer/director, the cute, cuddly, only-one-down-from-Gosling star Joseph Gordon-Levitt goes to bat against cold, casual sex and hits one into the mid-field for meaningful sex - even possibly older-woman sex - in Don Jon. This drama-comedy about compulsive sex and porn addiction is an uneven, bouncy story featuring characters that are admittedly stereotypes, but a storyline that could be a little too close to the truth for many and a wonderful scenario of a well-rounded life… that is headed to failure.

Raw fear is horror’s ideal state. The vertiginous drop through a trapdoor into primordial, gasping helplessness usually only lasts for the split-second length of a cinema-seat jolt. Jeremy Lovering’s debut aims to scare us for much longer. Unusually, he wanted to scare his actors too, feeding them just enough script to get by as they filmed on Cornwall’s Bodmin Moor (standing in for rural Ireland) at night, and he threw shocks at them out of the dark. Fear is his theme and method.

What happens when a citizenry marginalised by society and weakened by an illness that could well be fatal are also called upon to rise up to demand the treatment, not to mention the civility and compassion, that are their due? The answer is on often grievous yet ultimately heartening view in How To Survive A Plague, David France's immensely stirring chronicle of the activism - spawned in New York and then spun out elsewhere - that accompanied the first decade or more of the AIDS crisis. 

As a director, Alfonso Cuarón is a stickler. In his renowned Children of Men, he sought to dismantle cinema, to break down the glass wall between audience and content by making the film more like a live event. To a great extent, he succeeded, opening with a 17 minute continuous take and, later, using the expertise of Oscar-winning cinematographer Emmanuel Lubezski (known as Chivo), he would fashion takes of stunning length and complexity. No wonder that his next film, Gravity, took over four years to make: he needed to top his last one.

Feature films about ballet are rarities - are the memorable ones those that are realistic about their strenuous world or are they the expressionistic shockers that let rip with the red eyes and OTT fantasies? Black Swan became an instant world hit on the strength of its purple take on showbiz (never mind it was packaged in a ballet scenario, this was more a riproaring horror story). Love Tomorrow is altogether something else.

The 65^th Cannes film festival acts as the backdrop for this compelling, if somewhat misguided documentary from James Toback. Accompanied by Alec Baldwin, Toback sets out to shame Hollywood for its decision to continually churn out megabuck franchises and mediocrity rather than investing in risky, original cinema as the pair try to get funding for their own film project.

In 1998, Judi Dench slayed audiences on the London stage in Filumena, playing a former prostitute who learns belatedly to cry. The tears come more quickly - both for Britain's best-loved acting Dame and her public - in the comparably titled Philomena, the Stephen Frears film that tells an otherwise entirely dissimilar story about a doughty Irishwoman determined to locate the son wrenched from her a half-century or more before.

The working-class widow's accomplice in a quest that turned the real Philomena Lee into a publishing sensation is onetime BBC journalist Martin Sixsmith (Steve Coogan), who takes up the elderly woman's cause rather than write the weighty tome on Russian history that nags at his loftier journalistic impulses. Nor does it hurt that he has a beady-eyed Fleet Street editor (Michelle Fairley) thirsting for a scoop and to that end funding the pair's travels up to and beyond the point that Philomena, for one, ponders whether the pair ought not to call it quits.

That they persevere is no surprise given the film's origins in Sixsmith's 2009 non-fiction account of an odyssey that led this unlikely duo down many a blind alley and bureaucratic impasse before reaching a conclusion that finds room for anger aplenty amidst the sentiment. Nor will it come as news to hear that the odd couple centre-screen manage along the way to trade various life lessons before arriving at a (minimum) three-hankie denouement whose success in artistic terms owes something to that feeling of barely suppressed rage.It helps to have in Frears an abidingly honest director whose integrity is matched every step of the way by his sweetly wigged and accented leading lady. In lesser hands, this could have been merely the tale of a cute old Irish dear (Philomena more or less announces herself as that at the start) and the pent-up Oxbridge type who starts to soften under her tutelage. But just when the divisions between the two look set to go the standard-issue route, the film commendably widens its focus, stirring Reagan-era politics, the oppressiveness of the Catholic church, and the perennial appeal of the romance novel into an ever-thickening moral brew. You leave the film moist-eyed, to be sure, as well as wise to the hatred attendant upon so many in life. And that Philomena without a trace of sanctimony refuses to let into her heart. 

Coogan might be thought to pretty much be the film, since he not only co-stars but gets producing and co-writing credits, as well. And you can feel the serious actor in this celebrated comic tearing into the film's eleventh-hour broadside against organised religion in a face-off in Philomena's onetime convent that finds the magnificent Barbara Jefford in memorably implacable form. (Those who remember Peter Mullan's 2002 The Magdalene Sisters will discover equivalent terrain here.)

But the movie wouldn't be under Oscar's seasonal radar without the flinty, often funny presence of Dench, who sees out the occasional scripted lapse (an unnecessary confession scene, to start with) to compel interest in this quiet crusader - a kind woman whose will is sorely tested as she reflects upon the flesh-fearing environs from long ago that have eaten away at her since. Peter Hall once said of this actress that she possesses a unique combination of "sex and wit, wit and sex". To those qualities, add an unsparing emotional engagement, whatever the liberties taken with the actual narrative in its passage to the screen.

"Just because you're in first-class," an airborne Philomena admonishes her uppity companion, Martin, "doesn't make you first-class." (Serious product placement here for BA, by the way.) And who better to spout such homilies than that acting rarity: an unassailable class act?
