"There are no second acts in American lives," said F Scott Fitzgerald, but he had failed to include  Ben Affleck in his calculations. "This is a second act for me," announced Affleck, as he collected the Best Director award for his work on Argo at the recent BAFTAs in London, "and you're giving me that and this industry has given me that. I want to dedicate this to anyone else trying to get their second act - you can do it!"

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.    

Often it takes a generation or two before a country can address its dark days on films; Hitler didn’t feature in a central role in a German film until Downfall, in 2004. This timorousness was certainly the case in Chile, where in the immediate years following the end of General Pinochet’s dictatorship, in 1990, the local cinema was dominated by sex comedies.

Yesterday our film writers brought you numbers 10 – 6 in our movies of 2012 countdown. Looking back over that list it’s hard to imagine a clutch of finer films. Yet, testament to a year of remarkable filmmaking, it’s a hell of a race to the finish, taking in sex addiction, murder, spies, hostages and cults. And so we present our final five. Drumroll please…

5 – Once Upon a Time in Anatolia (dir. Nuri Bilge Ceylan)

It’s rare to get excited about a DVD release. It is even rarer to get excited about a director. Margin Call and its director JC Chandor are rare exceptions. Devised in 2005, the idea for the film came about when the director and his chums, testing the waters of the volatile yet lucrative New York property market, were offered $10m by a bank - few questions asked. By 2006, their plan of buying a building, renovating and flipping it became an undone deal as one of Chandor’s group pushed them to sell up - an act thatproved to be prudent in hindsight.

Julien Temple’s directing career has been struck seemingly stone-dead twice. After working with Malcolm McLaren and the Sex Pistols on The Great Rock’n’Roll Swindle (1979), then again after the flop big-budget British jazz musical Absolute Beginners (1986), he was made a notorious cinema untouchable in the UK. Exiled in Hollywood, he fell back on his parallel life as a landmark pop video auteur.

John Carpenter: Halloween II/Halloween III

Kieron Tyler

Hitchcock was fond of the locked-box mystery, but never in the obvious form: whether it’s the leads in Rope, stuck in their apartment with a body shut up in a trunk, or the survivors from a ship murderously bobbing along together in Lifeboat, the trap was all. James Stewart as LB Jefferies in Rear Window is another man locked in a box, this time kept in his apartment by his broken leg. But clever old Hitchcock – he sets the mystery outside the box.

“A dirty fairy tale” was one of the encomiums lobbed at The Apartment in June 1960, nine months before it won Billy Wilder and I A L Diamond the Academy Award for Best Original Screenplay and Wilder the Oscars for Best Picture and Best Director. Although The Saturday Review’s influential Hollis Alpert was critically off the mark when he disparaged Wilder’s serious adult comedy, he was right to describe it as a fairy tale. A prince does rescue a princess after an ogre’s cruel treatment of her has caused her to fall into a fatal sleep.

It would be an impossible to do a comprehensive global history of cinema in just 15 hours. You could attempt it by throwing hundreds of thousands of second-long clips at the viewer in a firework display of celluloid. But film-maker and critic Mark Cousins opts for gentle hypnotism over dazzling pyrotechnics. In the opening episode alone, in a lucid correlation of words and images, he shows us how filmmakers evolved a grammar for this new medium which took full advantage of an intrinsic plasticity which theatre, photography and painting lacked.
