Before his talk show So Graham Norton found infamy and acclaim filling the Friday-night saucy viewing slot on Channel 4 (a position formerly occupied by The Word, Eurotrash and the diabolical Denise Van Outen series, Something For the Weekend), Dubliner and one-time stand-up comic Graham Norton was probably best known to UK television audiences as the annoyingly chipper Riverdance-fan, Father Noel, in that episode of Father Ted where they have a caravan holiday. A seeming cross between a leprechaun on amphetamine and John Inman, Norton is a consummate ringmaster for the show's unique combination of audience embarrassment, celebrities, minor and major, game to be mocked with fawning irony (including Roger Moore and a number of ex-Bond girls, the divine Grace Jones, Catherine Deneuve and Mo Mowlam, among many others) and telephone pranks to unsuspecting fetishists abroad. On the DVD: In addition to the usual menus and chapter selection, there's a wry commentary from Norton in which he reveals he didn't like Billy Zane very much and that Mo Mowlam was unsuccessfully bullied by the spin doctors not to do his show. Plus, there's a six-minute interview with his nibs in which he cheerfully describes the show as "trivial fey nonsense" and defines "gay icon" as "someone who hasn't worked for 20 years or has done a really crap job for about 20 years". It concludes with a special message to DVD buyers: "Thank you for buying the DVD, and congratulations on being a little bit rich. I hope it doesn't end up being our generation's version of Betamax or a big audio-visual version of the Sinclair C5". --Leslie Felperin

Featuring a montage of highlights from his weekly Friday night series, Graham Norton: For Your Pleasure is a splendid showcase of the slickly uproarious, impeccably vulgar chat show host who is part Frankie Howerd, part Dame Edna Everage, part Julian Clary, but mostly himself. He hosts this programme in elderly make-up, enjoying the ministrations of a young manservant.

Norton fans will be familiar with the formula. Included here are quite outrageously lewd confessions from members of the audience, one of whom made love to a frozen chicken only to find his parents tucking into it the next day. But it's the guests who are the true staple of the show. Mostly women, mostly glamorous but just over the hill, and so willing to play good sports to Norton, they include Cher, Dolly Parton, Alison Moyet, Dolph Lundgren (who stoically endures Norton's flirtatious attentions) and David Ginola. The host doesn't so much interview his guests as regale them with surreal Internet clips of penguins tripping each other up or goats having heart attacks. They're also willing to dish a little dirt: Cybill Shepherd confides that "there was one thing Elvis didn't eat… 'til he met me".

Norton has priceless fun with Sophia Loren, who he has order a pizza named after her over the phone and play in a mock-EastEnders sketch, as well as introducing Martine McCutcheon to the delights of the Hot Cock, a microwaveable penis substitute. It's gross, camp, crude yet pulled off with great panache.

On the DVD: Graham Norton: For Your Pleasure comes with a droll commentary, in which Norton comments on the curious English accent Gillian Anderson adopted for the show and pours scorn on the cheapness of the props. He's also interviewed at length in his dressing room, where he proudly shows off the bizarre, vulgar and kitsch items viewers send him. Also interviewed is resident audience member Betty, elderly butt of his jokes, who reveals that her newfound fame enabled her to jump the queue at her orthopaedic ward. --David Stubbs

The Grand Canyon captured through IMAX technology, makes for a breathtaking video. The famous Powell expedition is splendidly recreated, taking the viewer through moments of ecstasy and fears faced then.
