POOR Eric Stoltz must be ugly or something. In his biggest films he is hidden under latex. In Mask he played the boy with the disfigured face and in The Fly II (Pearl, 9.30pm) he plays the boy with the disfigured everything. He is actually meant to be the son of Jeff Goldblum, the whacko scientist who met his maker in David Cronenberg's The Fly, which Pearl broadcast last night. Cronenberg left the sequel to Chris Walas, who did not do an entirely successful job on it. In parts it's averagely engaging, in other parts it's dull. Stoltz starts out as a five-year-old who has gained full maturity with the intellect to match. He is a hothouse child with a difference, but he has not yet worked out what the difference is. The scientists who are exploiting him knew his father and have guessed that Stoltz is about to undergo a metamorphosis. The Fly II is both sentimental and gory. THAT very British detective series Between The Lines (World, 1.15am) continues, with the customs department getting its knickers in a knot over a drugs bust gone wrong. They think it's a case of police sabotage. Neil Pearson, who made a name for himself on the British stage in productions such as Loot and Henry IV Part I, stars as detective Clark, a man caught between a rock and a hard place because of his compromising affair with a police colleague. THOSE of you who have been struggling for five years with 'your oranges are very nice' will have realised that Cantonese is not the easiest language. Help is at hand, according to Fiona Carver and Eye On Hong Kong (Pearl, 7.15pm), in the form of a new book that claims to teach you Cantonese in an instant. Geoff Wong, who should do something about his English first, interviews James Taylor and his band (the acid jazz James Taylor, not the one with the open-toed sandals). Gloria Wu meets Captain Jean-Luc Picard from the Starship enterprise and John Dykes reviews Robert Altman's fairly disastrous expose of the fashion industry, Pret-a-Porter. IN Sixty Minutes Plus (Pearl, 11.45pm) reporter Phil Jones goes underground with a woman whose husband was killed by a colleague. He has vowed to get her too, and has just escaped from a mental institution. Understandably, she is worried. TOM BELL, as popular in Britain as lukewarm beer, stars in Angels (STAR Plus, 2.00am), the story of three samaritans who descend to Earth to save three lost souls. But the real business of the day on STAR Plus is done in Donahue (12 noon) and The Oprah Winfrey Show (3.30pm and midnight). This is where the big issues come under the microscope. Phil Donahue, for instance, wonders what you do if you are having major surgery, one doctor leaves the operating theatre and the other is on probation. If it's a question that's been on your mind of late, Phil and his studio audience have the answers. And the title of today's episode of Oprah, meanwhile, is The Ultimate Bathing Suit Show. FILMS on Cable Movie Channel: Faith (7.00pm). The eponymous Faith is the daughter of a Vietnam fighter pilot who comes to America after being stationed in Germany. But all does not go well in the Land of the Brave and the Home of the Free. Faith's parents 'buy it' in a plane crash and she is left to fend for herself, until she is found by a local Mafia boss on the streets of Hollywood. Gudrun (1.00am). Friendship between two boys in World War II Germany, until one betrays the other's greatest secret. Scavengers (3.00am). A man studying endangered vultures in Africa gets caught up with the dastardly doings of the CIA. Ken Gillman and Brenda Bakke star. Lucky Dragon (5.00am). Two gangs disagree over the sharing of booty from a Hong Kong jewellery heist. The problem is taken out of their hands when a third gang turns up and steals the lot.
