It is easy to forget that despite the mini heatwave of the last few weeks, the real problem for the few remaining Hong Kong farmers has been rain. Just like farmers on the mainland, although thankfully not to such cataclysmic effect, local farmers have had their crops threatened by rising river waters and flooding. For most of us, flooding means delays and inconvenience. For the farmers, it can mean precious crops are swept away. It isn't easy being a Hong Kong farmer. Cheap mainland imports of vegetables present a real challenge to local producers, but the rising River Indus in the northeast New Territories is the greatest danger of all. In tonight's The Pearl Report (Pearl, 8pm) a special report considers the future for local farmers, and how the Government's plans to retrain the river might actually make the situation worse for some of them. The current temperatures also mean that the spate of Christmas programmes currently showing on the terrestrial channels is particularly irritating. Earlier in the week, Nurse Hathaway and Ross had a seasonal snog in front of the whole ward on ER (Pearl, Tuesday, 9.30pm), and Granny Carter delivered a Christmas tree the size of a small building. Last night, Steve Martin and John Candy struggled to get home in time for Thanksgiving (all right, not Christmas, but a wintry feast all the same.) Next week, Ally McBeal (World, Monday, 8.30pm) has problems of her own with a Christmas tree, and the horrible prospect of back-to-back Christmas parties. And tonight Ethan Hawke plays Knott, a scared US Army sergeant in the wartime drama, A Midnight Clear (Pearl, 11.35pm). In a moment of military madness, his superior officers instruct Knott to take his surviving men to capture a deserted chateau in the middle of a particularly inhospitable range of mountains. It is Christmas, and the last thing Knott and the squad want is any more shooting. Luckily for Knott and his terrified men, the only sign of the enemy is a gang of equally terrified Germans who just want the war to be over too. Saving Private Ryan this is not: no ultra-realistic battle scenes, no poignant reminders of the way warfare wastes young lives. But it is just as realistic to show fear, and how it makes all men on all sides equal in war.
