HIGHLIGHTS of the day's tennis championship being played in Victoria Park (Pearl, 11.50pm) will act as a warm-up to live coverage of the final stages of the HK tournament to be shown from Friday to Sunday. Top players taking part include Stefan Edberg, Ivan Lendl, Henri LeConte, Richard Krajicek and veteran crowd-puller John McEnroe. DIANE Keaton and Mel Gibson are the lead players in the well-made but gloomy adaptation of a true story, Mrs Soffel (World, 9.30pm, ORT 111 mins). Set in Pittsburgh in 1901, it's the tale of a woman, stifled by her life as the wife of a boring prison warden and by a repressive society, who makes a sudden and desperate bid for something better. Keaton plays the woman who, while distributing Bibles and blankets among the prisoners, becomes mesmerised by Jack Biddle (Mel Gibson), a condemned murderer on death row. She believes his claim that he didn't do it, and on a snowy Christmas Day helps Jack and his brother (Matthew Modine of Married to the Mob fame) escape. In the middle of the night she joins them on their desperate flight to Canada and freedom. The film looks handsome enough and the leads play their parts well, but it lacks any real emotional spark of passion. LA Law's Corbin Bernsen suffers a chronic case of typecasting in the TV mini-series Grass Roots (Pearl, 9.30pm, ORT 240 mins) playing, wait for it, an ambitious lawyer. Yo - really stretch yourself Corbin. He plays Will Lee, a southern lawyer who agrees to run for the senate, then finds himself embroiled in political intrigue and corruption. Mel Harris (Thirtysomething ) is Lee's CIA agent girlfriend, and the late Raymond Burr is a local judge, who forces Lee to defend a young man in a controversial, and potentially explosive murder trial, which could wipe out his political career before it's started. The second part of the mini-series will be shown same time next week. GUITAR maestro and singer Eric Clapton not only had a massive seller with the recording of his Unplugged show, but also won an armful of Grammys for his acoustic effort. Tonight there's a special broadcast of that show (MTV, 2am), for which note style clips will run along the bottom of the screen culled from an interview in which Clapton talks about the inspiration for each song. THAT'S followed by a more recent mega-star of the music biz, Whitney Houston, who's the subject of this week's Rocumentary (MTV, 2.30am). The programme includes footage of Houston with husband Bobby Brown and their baby, and she'll discuss her singing career and her film debut in The Bodyguard. Perhaps she can explain Kevin Costner's Julius Caesar hair-cut. IF you have time spare in the afternoon, don't miss the delightful Miss Pym's Day Out, a special edition of Bookmark (BBC, 3.25pm). It's a fanciful dramatisation of novelist Barbara Pym (Patricia Routledge) visiting London in 1977 to attend the Booker Prize ceremony at which her novel Quartet in Autumn was shortlisted. Blending fact and fiction, the film sees Pym meeting characters from her novel as well as literary friends. HUMANS can't choose the sex of their babies - that's down to a biological lottery - but for freshwater crocodiles, fairy wrens and the humble polychete, is a different story, according to Australia Wild (World, 8.30pm). Crocodiles, apparently, do it by temperature - amazing, you'd think the thermometers would break in such jaws.
