Michael Powell fell in love with his celluloid mistress in 1921 when he was 16. It’s a love affair that he’s conducted for 65 years. At 81, he’s not stopped dreaming of getting behind the camera again. At Cannes this year he hinted at plans to make a silent horror film, but he’s reluctant to talk about it.

Nobody ever forgets The Red Shoes (1948) because it’s a movie that seems to change the way an audience experiences cinema. A story about a diverse group of individuals collaborating to make art, the film is itself a wonderful example of the process.

No-one could joke about the tragic aspect of Orson Welles’s career, the fact that his inestimable promise had only been partially realised, better than Welles himself. Once, when asked about the outrage following his panic-inducing radio adaptation of War of the Worlds, the director quipped, “I didn’t go to jail. I went to Hollywood.” And that was punishment enough.

French actress Marie Rivière had a specially close relationship with director Eric Rohmer. After seeing his work for the first time in the early 1970s, Rivière expressed her admiration in a letter, which led to a succession of parts and culminated with her appearing as heroine Delphine in Rohmer’s 1986 The Green Ray (Le rayon vert): the part was in some way centred on the experiences of the actress, who was allowed to develop the story through almost total improvisation.

The newly restored, 111-minute cut of M is being screened 35 times during BFI Southbank's current Peter Lorre retrospective. One only has to see and hear Fritz Lang's first sound film once, however, to appreciate its undiminished power as a vision of a Germany teetering on the abyss less than three years before the Nazis took power.

A pair of Oscar hopefuls that take wildly divergent perspectives on World War II were confirmed today as the opening and closing night films of the 58^th annual BFI London Film Festival, running 8-19 October at a range of venues across the capital.

In what is undoubtedly one of the earlier recorded examples of the single entendre, the original ad campaign for Some Like It Hot yelled “Marilyn Monroe and her Bosom Companions”.

It begins with two gunshots. Lee Marvin is a guy who just wants his $93,000. "I want my money" is the mission statement for Point Blank, a film that is as timelessly entertaining as it is influential. But putting it that way doesn’t grab the sensation of watching a film that is so exciting you may forget to breathe for all 92 minutes of it.

"When you're making a movie, it's a movie; if they're still talking about it in 10 years' time it's a film. If they're still talking about it in 50 years' time, it's cinema. But you sure as hell can't start out making cinema." Legendary studio head Ned Tanen knew his business. That we’re talking about Lawrence of Arabia 50 years after its release confirms it as cinema - a word suggesting art taken to genius level, and Lawrence of Arabia is exactly that.

Shadow of a Doubt was reputedly Hitchcock’s personal favourite among his films. Joseph Cotten was cast against type as the glamorous, homicidal uncle, fleeing from the police and pitching up unexpectedly in his sister’s household in a sleepy Californian town. Hitchcock’s decision to shoot Thornton Wilder's script largely on location gives the film a unique flavour.
