The shock of no longer being young and carefree – that’s the message in director Judd Apatow’s funny and poignant fourth feature, a ‘sort of’ sequel to Knocked Up. In the long tradition of Fellini and Woody Allen - where a lead actor is the director's alter ego - Judd Apatow's onscreen self is Paul Rudd. As Pete married to Debbie (Leslie Mann, Apatow’s real life wife), he plays a father and husband confronting the scariest mundane thing in life: the idea that he's no longer young.

Does it matter if film dies? Keanu Reeves, always cannier than his limited acting style suggests, produces and presents this even-handed documentary on analogue’s apparently fatal decline in the face of a very recent digital onslaught. His contact book brings enviable witnesses to the stand for director Chris Kenneally. If the world-famous directors and generations of legendary cinematographers don’t know the answer, maybe there isn’t one yet.    

They’re in trouble. They had to be. Otherwise there’d be no drama. And if you’re a fan of Richard Linklater’s Before Sunrise (1995) and Before Sunset (2004) skip the next two paragraphs to avoid knowing where, physically, temporally, Céline (Julie Delpy) and Jesse (Ethan Hawke) have arrived since the poetic ending of the 2004 film.

Great fun on day three in Berlin: Scarlett Johansson co-stars in a porn movie. Well, a movie about a young man’s love of porn sites, in which she flashes her famous curves - and starts sleeping with Jon Martello (Joseph Gordon-Levitt). But Jon, a swanky, body-building Roman Catholic, is soon dumped; Johansson’s Barbara Sugarman sees no future in being jilted by a laptop and tissues.

Is Prokofiev’s 1938 score for Alexander Nevsky the greatest film music ever written? Not quite, if only for the fact that Sergei Eisenstein’s second sound-picture glorifying historical role models for the ever more tsar-like Stalin, Ivan the Terrible, is darker and more richly textured, and the music’s greater breadth reflects that.

Ecology at the first full day of the Berlin film festival. An intriguing Matt Damon city-versus-country movie, Promised Land, puts fracking into the mainstream for the first time. Damon plays Steve Butler, an eager corporate buyer of leases in rural America to enable his New York employers Global to start deep drilling for massively lucrative natural gas.

A colourful confection which is certain to satisfy both the young and young at heart - and above all, gamers - Wreck-It Ralph is the conceptually fabulous, aesthetically various tale of a brick-brandishing brute who longs to be a hero. The cinematic debut of TV director Rich Moore (Futurama/The Simpsons), it features the voice talent of John C Reilly and Sarah Silverman and boasts not just a third dimension but a meticulously constructed universe.

A pedestrian talent hitches a ride on genius in Hitchcock, director Sacha Gervasi's often cringemakingly banal look at the filmmaker in the run-up to the mother of all horror movies, Psycho. One can only imagine what the Great Man himself would think of a film that applies rudimentary psychology to a celluloid classic that gets under the skin to an extent Gervasi can only dream of.

Although I Give It a Year seems to have more than a whiff of a Richard Curtis rom-com about it, don’t be fooled as this is the debut of British writer-director Dan Mazer, the co-writer of the emphatically more outré Brüno and Borat, along with various incarnations of Ali G. Furthermore he’s lobbed Scary Movie's Anna Faris and Bridemaids' Rose Byrne into the mix.

There’s an episode in the first season of Mad Men in which the ad execs of Sterling Cooper brainstorm a campaign for Richard Nixon, just prior to the 1960 presidential election. Dramatic irony being what it is, it’s a rare opportunity to watch our anti-heroes working on a pitch (based chiefly around smear tactics) that is predestined to fail. By contrast, Pablo Larraín’s No chronicles how a team of ad men in 1980s Chile, led by Gael Garcia Bernal’s maverick René, put together a campaign to topple a dictator that we know will succeed against all odds.
