Everyone's favourite investigative smoothie Nick Broomfield updates his 1991 doc Selling Of A Serial Killer by re-cataloguing the tragic, shambolic life of Aileen Wuornos (from homeless woodswoman to vagrant prostitute to multiple murderer) and finally interviewing a clearly demented Wuornos only hours before her execution. More sombre than the usual Broomfield outings, but effective all the same.

Listen to Kate Rusby's records and her brand of folk revivalism suggests a rather serious and high-minded young woman. Yet in concert she's a revelation, interspersing sublime versions of traditional folk ballads with rambling but engaging introductions full of homely Yorkshire warmth and wit. Rusby makes folk music seem like fun again, and the feeling never flags throughout this 90-minute set.

Written as a student project with future Alien writer Dan O'Bannon, John Carpenter's ingenious no-budget directorial debut, named after a Grateful Dead song was the first stoner sci-fi pic. On a scuzzy spaceship far away, four furry freak surf dude astronauts are bored out of their skulls on a long-haul mission to destroy unstable planets, and plagued by troubles when their talking bomb gets ideas of its own and the alien "pet" O'Bannon has smuggled aboard escapes. Sideswipes at Kubrick's 2001 are entirely intentional; the attack of the munchies the movie brings on pure coincidence.

Fritz Lang's seminal 1922 thriller unleashed cinema's first modern criminal, Mabuse, a shadowy underworld figure with a thousand faces. Combining technological genius with an almost occult ability to terrify, Lang's Mabuse is a sinister, manipulative mastermind. The 1933 sequel, The Testament Of Dr Mabuse, is even better, with Mabuse as a demonic Hitler figure. Everything from Bond to Blue Velvet starts here.

In its 1946, Hays Code day, this adaptation of James M Cain's novel was provocative and erotic, although it was later out-raunched by the '81 Jack'n'Jessica version. This drips with textbook noir, and echoes Double Indemnity in both story and style. Femme fatale prototype Lana Turner tempts John Garfield to off her husband, but their comeuppance is inevitable. "He had to have her love—if he hung for it!"

There's a saying in the pubs of Dublin that there are only two kinds of musician—the Irish, and those who wish they were. The likes of Emmylou Harris, John Prine, Richard Thompson and the Everly Brothers prove it by lining up alongside some of Ireland's finest in 20 performances designed to showcase the global influence of Celtic music.

Orson Welles' darkly comic 1963 adaptation of Kafka's paranoid fable is still visually stunning, with an unforgettable performance by Anthony Perkins as the hapless Josef K, placed on trial for reasons unknown. "He's guilty as sin," was Welles' verdict, and so Perkins plays it all the way as a shifty, twitchy ball of nerves. Superb.

Pretty funny farce from the Farrellys: not back to their best, but at least regrouping. Greg Kinnear and Matt Damon are conjoined twins who leave smalltown life to seek fame in Hollywood. Evil Cher's mad scheme backfires, and they make it. But what they really want is love...awww. Sweet and slick, with fine gags like, "He's drinking; I'm the designated walker."

As South Africa celebrates the 10th anniversary of Mandela's election, Lee Hirsch's documentary, which won a brace of awards at the Sundance Film Festival, pays moving tribute to the central role music played in the struggle for liberation. Contributions from the giants of South African music like Hugh Masekela, Miriam Makeba and Abdullah Ibrahim are intercut with footage showing the horrors of apartheid.
