MOVIE mania swamps our small screens tonight as four (reasonably good to great) films come our way - the best pick being One Good Cop (Pearl, 9.30 pm. Original Running Time 105 mins). The hard working Michael Keaton is back again, this time in this dramatic and touching story about an honest cop who fosters the three daughters of his best friend and partner after he is killed on duty. With the added financial burden of his new family he finds making an honest living a difficult task. Corruption becomes a temptation. Keaton proves his reliability as an actor by bringing a certain emotion to this role not found in many of his other films. Rene Russo and Anthony La Paglia co-star. IF you are in less of a dramatic mood a bit of fun can be had from World's feature Weekend at Bernie's (9.30pm. ORT 98 mins). Filled with mobsters, murder and mayhem, this riotous film tells of two young insurance workers who accidently uncover their boss's (Bernie: played by Terry Kiser) corrupt transactions, unaware of his actual involvement in them, and become the target of his connections with the mob. Expecting a big promotion they are invited to his seaside condo where they are bemused to find him dead, triggering a wild weekend of sun, sand, girls and danger. John Silverman plays Richard, the power hungry employee, and Andrew McCarthy is back again playing his usual nerdy role, this time as Larry. ON the documentary front, Pearl is running a rather worrying documentary on the plight of Southeast Asia's precious tigers in The Tigers of Thailand (8.30 pm). Victims of the rampant poaching sparked off by the high prices paid for their furs, the big cats are rapidly decreasing in numbers in the wild and could be on the brink of extinction within the next few years. And this programme reveals it is not only their hides that are now highly prized. Tiger meat is also becoming common on the more exotic menus of Southeast Asian restaurants leaving the future for this jungle predator looking rather bleak. EDDIE Murphy's Harlem Nights (Pearl, 12.00 am. ORT 118 mins) took the cinematic use of expletives to its outer limits in theatres four years ago, so the territory's censors must have had a ball preparing the television version TVB is featuring tonight. Produced, directed, written and starring Murphy, this film, though good, was considered a bit of a flop by critics. It is basically a gangster comedy set in 1930s Harlem, about the troubles experienced by a night club owner who gets hassled by the mob and corrupt police. It also features Richard Pryor, Red Foxx and Arsenio Hall, but the script fails to bring their talents to the fore making the great music score from Herbie Hancock, including some classic jazz standards, the film's highlight. TONIGHT'S violence, blood and gore comes from Quiet Cool (World, 12.55 am. ORT 86 mins). James Remar, better known for his convincing portrayals of baddies, swaps roles in this film about a tough city cop who is out to bust a marijuana growing syndicate and along the way employs the help of two victims of the gang (played by Adam Coleman Howard and Daphne Ashbrook).
