IF you have not yet caught up with Beverly Hills 90210 (World, 7.05pm) now is the time to do so. This is the teenage drama that adults watch. It stars Shannen Doherty, the brat who put the brat in brat-pack and was recently accused of trying to run down her millionaire fiancee when he told her their engagement was off. She went further than that, threatening to do something to him that would have altered, temporarily at least, his gait. Ms Doherty has elevated bad behaviour to an art form. She is being evicted from her apartment for not paying bills, had a fight in a Beverly Hills nightclub with another woman and allegedly tried to hire prostitutes from Heidi Fleiss for a party she was throwing. When Fleiss demanded US$200 each, Doherty told her where to go. This all detracts from the television series, but is more interesting. Ms Doherty plays petulant Brenda Walsh in the show, but in real life has become so notorious that she has spawned an anti-fan club in the US. Glamour magazine named her Prima Donna of the Year. If you are interested in watching Beverly Hills 90210 (it's a postcode, not a telephone number) this is the story so far: Doherty is Brenda Walsh, female half of the Walsh twins. The other half is Brandon (Jason Priestly). Their cousin Bobby is coming to stay, but he turns out to be in a wheelchair. More important than the mobility-impaired cousin is that Brenda has to take her driving test for the third time. If she fails the kids at school will laugh at her. IT is difficult not to like a film that is as downright stupid as Crocodile Dundee (World, 9.35pm). The fish-out-of-water storyline is a comedy standard, but Paul Hogan - who became an Australian phenomenon after the film was released in 1986 - carries it off with undeniable charm. Crocodile Dundee is good-natured, amiable and often very funny. Hogan is Michael J. 'Crocodile' Dundee, a crocodile hunter who is paid to show a pretty American reporter (Linda Kozlowski) around Bush Country. She then shows him around New York, where he finds everything strange, particularly the people. THE wartime cliches flow like water in Memphis Belle (Pearl, 9.30pm), a David Puttnam-produced drama about America's 'flyboys' of World War II. The boys (Matthew Modine, Billy Zane, Sean Astin and others) are the crew of the Memphis Belle, a B-17 bomber which is due to fly its final mission over Germany. If the boys get home with all their limbs in the right place, they are to be rewarded with a posting back to America. The odds demanded that one in three would not return - and most were barely out of their teens. Duck the cliches if you can and enjoy Memphis Belle for what it is. THE plot of An American In Paris (World, 2am) was showing signs of age well before 1951, when the film came out. It centres around Gene Kelly, an ex-GI and struggling artist in post-war France. But everything else more than compensates; Kelly's choreography, the Gershwin Brothers' songs and Vincente Minnelli's direction. It won an Oscar for Best Picture. THE documentary mini-series JFK: The Last Kennedy Film (Pearl, 8.30pm) has not been answering the questions it has been asking, but it is in good company. Did the President sleep with Marilyn Monroe? Was she bumped off by the CIA? Was it the mob? The conspiracy theories are thick on the ground. The safest conclusion we can draw is that there will be more documentaries asking the same questions, and failing to answer them. IN Macau you can get Gunga Din (TDM Channel 1, 11.05pm), which has everything - humour, suspense, spectacle, racism, imperialism, xenophobia and Cary Grant. Gunga Din cost US$2 million to make and wowed them at the box office. It's part Three Musketeers and part Laurel And Hardy, but it is difficult to overlook the blatantly racist nature of the proceedings, which endorse British imperialism and the violence inflicted on the Indian people.
