IF action-packed adventure movies are your bag, then The Accidental Tourist (World, 9.30pm, Original Running Time 121 mins) will probably leave you snoring. But anyone with the time to sit back and enjoy this slow-moving, romantic comedy-drama, will be drawn in by its gentle charm. William Hurt gives an exquisite performance as Macon Leary, a writer of travel books for businessmen who hate to travel. Abandoned by his wife (Kathleen Turner) after the death of their son, Hurt returns to the bosom of his eccentric, obsessive family and runs into kooky dog-trainer Muriel Pritchett (Geena Davis), a woman who's definitely not his type. Davis (Thelma and Louise ) won an Oscar for her role, though it's Hurt's understated performance on which the film hinges. There's also fine ensemble acting from David Ogden Stiers, Ed Begley Jr and Amy Wright as Hurt's quirky reclusive siblings who devote their time to storing the groceries in strict alphabetical order, playing a card game so complicated no one outside the family can keep up and steadfastly refusing to answer the phone. THE action is based on friendship and rivalry between two free-divers - they dive without aqualungs - in the beautiful, but silly, water-logged movie, The Big Blue (Pearl, 9.30pm, ORT 119 mins). Jean-Marc Barr and Jean Reno have been free-diving since they were children and the shots of them plunging into the deep are exciting - for a while anyway. Enter Rosanna Arquette to revive her ditsy routine from Desperately Seeking Susan, this time playing an insurance investigator who falls for Barr. The problem is the story's as daft as she is. SINGER/songwriter Andy Ingkavet and band Hot Sauce are on Eye on Hongkong (Pearl, 7.20pm) to discuss their hopes for the future. There's also a look at attempts by the Cricket Association to make the sport more popular here. Efforts have resulted in the formation of an all-Chinese cricket team to play in Taiwan in September. And David Johnson will talk about the joys of being the owner of a 1955 Buick Special. ACCORDING to its makers ABC/Kane, Secret Weapons (Pearl, 8.30pm) is a ''fact-packed look at the frenzy and fury of war-fuelled advances in the secret technology of battle''. Can't believe that in 1993, war is still being glamourised. The first episode examines the role of the jet engine in war. PEARL'S second new series Code 3 (9pm) was made as a result of the craze in America for ''reality television'', which means it's a morbid exercise in ambulance-chasing. A Code 3 is the term used by American emergency services for top priority calls. In this series, host Gil Gerard and his cameramen follow the rescue units - fire department, air rescue or ambulance - to the scene of the call and record how they deal withit. FILM-watchers still vainly waiting for Howards End to reach Hongkong, may like to console themselves with another, much earlier, Merchant-Ivory production, Autobiography of a Princess (STAR Plus, 12.10am, ORT 59 mins). Yet again, the theme is Imperial India, this time seen through old home movies being watched by the blinkered daughter of a Maharajah and the latter's former tutor. Madhur Jaffrey (whose cookery series is currently shown on the BBC) plays the daughter, and James Mason is the retired tutor. The occasion is their annual get-together for tea to celebrate her late father's birthday. While Jaffrey's loyalty is unswerving, Mason becomes increasingly angered as he remembers the monstrosities of the regime and his own weakness. Worth watching for Mason alone.
