After a timid first season, Smallville gets evil and horny—at least in a nice, family viewing kind of way. Young Clark Kent comes across red Kryptonite and turns moody; cue much pondering on whether he's been sent to Earth as saviour or destroyer. The love interest with Lana warms up, but in "Heat" Clark, like everyone, falls for a sexy new teacher. Educational.

Underrated, atypical Brit film from Penny Woolcock, smartly mashing up the thrills of Fight Club with the what-are-we-here-for musings of French existentialism. Marc Warren and Alec Newman are competitive males into bareknuckle bouts, drugs and strippers; Sienna Guillory is the single mum they soften for. Confused climax, but till then alarmingly gutsy.

Veteran Japanese director Yoji Yamada's 77th film recasts the Samurai epic with a fin-de-siècle cynicism reminiscent of the revisionist westerns of the '60s and '70s. In the dying days of 19th-century Japan's Edo period, a reluctant Samurai (Hiroyuki Sanada) fulfils his duties while dreaming of settling down. A beautiful, moving deconstruction of national folk myths.

"O JOY!"IS NOT THE UNIVERSAL response to the idea of a sofa, a bag of toffees, a long weekend and six Marx Brothers movies to sit through. Inexplicably, there are those whose funny bones are immune to the work of Groucho, Harpo and the rest of the crew. When it comes to the Marx brand of sideways lunacy, seems you either get it or you don't. This latest DVD set gathers up A Day At The Races, A Night At The Opera, At The Circus, Go West, The Big Store and A Night In Casablanca.

Along with Boyz N The Hood, this marks the film world's awakening to a dark period of gang violence in early-'90s LA. The story of Caine Lawson (Tyrin Turner), a young black man looking to escape the daily treadmill of bloodshed, isn't particularly original, but the Hughes brothers pull few punches. It's not a pretty sight, but the film now stands as a curious period piece.

Left limbless, deaf, dumb and blind by a WWI landmine, US GI Timothy Bottoms is locked away in a hospital. Considered beyond medical help, he drifts in memories and fantasies, until, years later, he finally finds a way to communicate—to little avail. Based on his 1939 novel, this 1971 anti-war parable was the only film directed by blacklisted scriptwriter Dalton Trumbo. At times awkward, it's nonetheless driven by an acute, angry intelligence. Hard to forget.

Gus Van Sant's Palme d'Or-winning take on the Columbine massacre makes for understandably difficult viewing. Van Sant deliberately shoots the movie flat and spare, looping the story, Rashômon-style, through numerous viewpoints. The Groundhog Day tedium of school life and the blank-eyed stares of the killers are chilling.

In 1968, Raybert productions—a Hollywood hotbed of drugged-out '60s fornication—saw fit to hand would-be-Fellini Bob Rafelson The Monkees as a vehicle for his auteurist debut. This was the result.

Part of the BFI's intriguing "A History Of The Avant-Garde" series, this is 66 minutes of decaying, nitrate-film archive footage, an artful collage in which figures deteriorate as we watch. Obviously, it's heavily symbolic: nuns, children, boxers go about their endeavours unaware (or are they?) of the oblivion that looms. The dissonant score's a drag, but this is nothing if not haunting.

In 1980, one year before Anthony Burgess composed a whole new language for Quest For Fire, the producers of this dumbass Neanderthal comedy achieved much the same effect by just having actors go "oog". Insanely, Ringo Starr plays a horny caveman who forms his own tribe of losers (a young Dennis Quaid among them) and gets into scrapes. A must-have for Beatles completists; for everyone else, the animated dinosaurs are sweet. (DL) DVD EXTRAS: None.
