THE big-budget, high-powered World War II espionage thriller Where Eagles Dare (Pearl, 9.30pm) is your archetypal schoolboy adventure, rather unattractively photographed, but containing the usual variety of excitements and in enough quantity to make it enjoyable.
Of course it's all a bit hard to credit (especially since the poor Germans can't seem to hit anything with their machine guns - present them with a barrage balloon at two feet and they would hit the trees instead), but that's part of the fun.
Richard Burton, in a switch from the heavy dramatic roles that made him famous, is excellent as our hero, John Smith, who leads an elite group of Allied commandos assigned to rescue an American general who is being held captive in a castle. But it is Clint Eastwood who makes it all worthwhile.
He is the young American lieutenant with an individualistic streak. Mary Ure and Ingrid Pitt, as an agent called Heidi, provide respite from all the men.
THE thriller Knight Moves (World, 9.30pm) is a bit ridiculous, with little suspense or sense of reality. A chess champion (Christopher Lambert) is suspected of being a serial killer. The real killer, meanwhile, presents him with teasing clues.
THE formula for The Cosby Mysteries (Pearl, 1.05am) is part family sitcom, part Agatha Christie with contemporary American mores. A dastardly guest star commits a crime that baffles everyone except Cosby (and the viewers). But soon enough clever Cos outwits the perpetrator, confronts him with his misdeeds and sends him to justice.
