YOU had best get used to the Beatles. Second comings have so far been limited to the one detailed in the Bible, but this is already taking on quasi-religious proportions. The Beatles Anthology Countdown (Pearl, 9.30pm and 11.50pm) begins this evening, as a run-up to The Beatles Anthology itself, which airs next week. And you can't escape by turning to STAR Plus. Donahue (4am) promises secrets from Ringo Starr, the one on drums. Racing Night Live (World, 8pm), with Terry Spago and friends, is not scheduled for a second coming because it has never been away. It is difficult to criticise because the multitudes watch it. Bums on seats is the thing, but the rest of us are left to wonder what it is about Racing Night Live that is so appealing. Certainly not Spago, or the strident Australian woman with big hair who sits next to him. Night Of The Film-maker (World, 10.30pm) is all that is left on World, a documentary about digital image building and editing technology. It might be interesting for viewers with a particular fascination for digital image building and editing technology. SO thank goodness for ER (Pearl, 8.30pm) which established its formula early on and never wavered from it, even last week when Quentin Tarantino was called in to direct an episode. Tarantino did some mildly interesting things with a major surgery scene, and again with a patient who lost his ear, but his direction seemed confined by the groundrules. You can't do much with a 55-minute made-for-television hospital drama other than have a few people get sick and then either get better or die. In this evening's episode nurse Hathaway and Dr Taglieri are due to get married, but something in the tea leaves tells me all is not going to proceed as planned. IT is becoming traditional for Pearl to broadcast things in the wrong order. Recently it was the final instalment of The Godfather films; this evening it is The Karate Kid Part III (Pearl, 9.35pm), which is the last in the series, and by far the worst. The 'kid' is played by 27-year-old Ralph Macchio, who was fine for the part in the first film in 1984, but when this was made in 1989 was getting a bit long in the tooth. The original The Karate Kid was an unabashedly old-fashioned, manipulative movie that was a real pleaser with the international multitudes. This is utterly stupid, with Macchio being set up for slaughter by his old nemesis (Martin Kove, in an obligatory appearance). When Pat Morita refuses to train him he turns instead to a sadistic millionaire Vietnam veteran - who turns out to be a buddy of Kove's. Will the sagacious Morita step in and save him? Naturally . . . but this film is hopeless. GLORIA WU, who has made a career out of wearing the kind of earrings no other woman in her right mind would wear, hosts Pearl Movie Watch (Pearl, 8pm). The bloke with the gelled hair and open-neck shirts is John Dykes, who reviews some of the new films in Hong Kong. FILMS on Cable Movie Channel: Love And Fear (7pm). Involving if melodramatic account of the lives and loves of a trio of sisters: the oldest (Fanny Ardant) is an intellectual and all too aware of passing time and advancing age; the middle one (Greta Scacchi) has no professional identity and lives by her emotions; the youngest (Valeria Golino) is a passionate, idealistic medical student. Loosely based on Anton Chekhov's Three Sisters and crammed with ideas and observations about how life is in constant flux. Triad Story (9pm). Director Shum Wai's attempt to illustrate gaps between the triad societies of old, who allegedly had honour, and the new generation of organised criminals, who are thuggish and have no standards. Stephen Chow, Wu Ma and Ke Jun-xiong star. In The Line Of Duty: Ambush In Waco (11pm). Made-for-television quickie tries to cash in on the deaths of cult members and their leader David Koresh in Texas.
