IT'S the little programmes that count tonight. The likes of The Simpsons, Man's Heritage, M.A.S.H. and Entertainment Tonight have more to offer than the primetime movies. World's is Narrow Margin, which is an exciting enough thriller, but was only on a few months back. Pearl, meanwhile, has fallen headlong into a bucket of blood with its Halloween film series, umbrella-titled The Big Scream - The Big Yawn would be more appropriate. IF you did miss Narrow Margin (World 9.30pm, Original Running Time 97 mins) last time, it's worth checking out for the customary good performance from Gene Hackman and the even better one from Anne Archer (Fatal Attraction ). Assistant DA Hackman is escorting reluctant witness Archer to testify at a murder trial, initially unaware that hoods have boarded the same train to ensure she doesn't get there. As with all good train movies this one has a spectacular action scene atop the moving vehicle, complete with dramatic backdrop courtesy of the Canadian Rockies. Richard Hyams (Running Scared ) directed and throws in enough heavy-duty action to keep the action punters happy. Admittedly, his version is not quite as good as the 1952 original, but it only runs out of steam towards the end. FOR a little psychotic carnage, try suffering through Silent Night, Deadly Night 4: Initiation (Pearl 9.30pm, ORT 90 mins). It involves Fima (Maud Adams) and her demented assistant Ricky (Clint Howard) trying to recruit new members for their unholy club, by putting them through a bizarre, horrific initiation ceremony. It's your average splatter movie, though it seems to have nothing in common with the first three films in this series, all of which involved psychopathic Santa Clauses. In fact, theatres in the US which showed the first film were picketed by outraged Santa supporters who didn't want to see his good name besmirched. STILL in Halloween mode, but in rather more palatable form, The Simpsons (World 9pm) are telling each other tales of the macabre in an episode entitled Tree House of Horror III. Homer's story is about a killer Krusty Doll, while Bart's - as you'd expect -involves half of Springfield's residents having their brains sucked out. Watch the credits at the end to see how the whole company got into the Halloween spirit (sic). THEY wage long-term wars, they take slaves, they're fond of landscape gardening and they thrive from Sahara to sub-Arctic. Who are they? Ants, that's who: the gi-ants of the insect world who are so prolific their total bodyweight matches that of the humanrace. Professor Edward Wilson shows how remarkable they really are in Man's Heritage: The Little Creatures Who Run The World (Pearl 8.30pm). LOOKS like Simon McCorkindale's going to meet his match in this week's instalment of the disastrously funny Manimal (STAR Plus 9.30pm). He's out to rescue a lass who was raised by wolves in India. Sounds like a potential spin-off series in the making - you never know, perhaps they'll muster as much imagination as for the original, and call it Womanimal. ASIA'S World Cup Qualifying matches being played in Qatar have reached the final rounds. Live coverage of the games continues on Prime Sports with the potentially explosive match between South Korea and North Korea (9pm), Saudi Arabia versus Iran (11.15pm) and Iraq playing Japan (1.15am).
