I n Focus: Sexy Swimsuits World, 9pm TVB did not dare show us Mel Gibson's naked rear in its recent screening of Lethal Weapon. But as one would expect, there are plenty with minimal coverage exposed in this fashion magazine. Equally unsurprising, most of them belong to beautifully tanned female models, who show off the 'boobini', 'tankini' and 'bando' swimsuits, not to mention naughty fantasy outfits featuring beloved fairy tale characters such as Little Red Riding Hood and Snow White. A naked rear is out, but one in a G-string is fine. But beyond the obvious sex appeal factor, this programme is surprisingly in touch with the reality that most of us are not as well-built as the scantily clad presenter Daisy Fuentes. We can, though, still look good in swimwear. It is just a question of finding the right costume, and understanding what flatters particular contours. There are a few male bodies to admire too, though many agree they look best in the latest baggy surfer shorts. Several bizarre facts - such as that some swimsuits must be dry cleaned only - are also revealed. Anorexia World, 10pm There is probably some connection between the dream of looking slim in swimsuits and the dangerous eating disorder anorexia nervosa. But one point that does come across in Sexy Swimsuits is that the skinniest bodies look shocking in bikinis. The eating disorder is explored in Anorexia, a German documentary that follows three girls in their fight against the disease, finding hope in a private Canadian clinic. Their stories show this is a complex illness that requires nursing of the mind as well as the body. The people most qualified to help are those who have lived through the experience themselves, and survived. Hostile Hostages Pearl, 9.30pm A simple jewel thief (stand-up comic Denis Leary) finds himself trapped in a fate worse than jail when he kidnaps an obnoxious and argumentative couple (Judy Davis and Kevin Spacey, above with Leary) after bungling a burglary. He holds them in their home while they prepare to receive their Yuletide guests, including son and sundry relatives. Faced by the family crisis, Leary has no option but to explore new talents as a marriage counsellor, or Ref, as this entertaining, well-cast comedy was originally called (1994). Australia's Flying Foxes National Geographic, 9pm With ever more people moving into bat territory in Australia, the 'flying fox' (above), as it is known Down Under, has become the object of antagonism. The bat's new human neighbours find them smelly, loud, and disagreeable. But a Brisbane biologist is an exception and spearheads a campaign to save them. She wants legislation to protect bats and rainforest replanted so they can be returned to their natural environment. Hollywood Squares Star World, 6pm Whoopi Goldberg, Billy Crystal and Robin Williams have worked as a team for the past eight years on the Comic Relief fund-raising telecasts in America. This week, the trio unite again, to up the star quality and laughs on Goldberg's game show, with the two comedians entering the squares, where Donny Osmond, Raquel Welch and Bo Derek, among other celebrities, have been before.
