One critic actually knocked The Pagemaster (World, 8.30pm) for being little more than an expensive animated plug for public libraries. But even if that were true, what is wrong with that? Macaulay Culkin, who was still single then, stars as Richard, a lonely bookworm who meets up with a thoroughly creepy librarian (Christopher Lloyd) who takes him on a magical mystery tour to the world of Children's Fiction. His other travelling companions, Horror, Fantasy and Adventure, voiced by Frank Welker, Whoopi Goldberg and Patrick Stewart, introduce him to characters familiar to all well-read kiddies, Captain Ahab, Mr Hyde and Long John Silver. These characters stand in the way of reaching the exit sign, Richard's only route back to the real world. This movie is perhaps not Culkin's greatest achievement, but the poor kid was at the end of his cute phase then, and his star was waning. Today, of course, he is a happily married teenager, who has yet to make the leap into teen roles that he needs if he is going to outlive his child-star reputation. The early marriage need not necessarily be as big a disaster as everyone seems to think - look at Elizabeth Taylor. She married the first time at 18 too, and went on doing it until she realised she didn't have the knack for it. It may not have made her happy, but it certainly kept her in the public eye far more successfully than any of her films have. In tonight's S Files (Pearl, 8.30pm), Dr Susan McKinnon is hailed as a latter day Christian Barnard for her pioneering work in sticking patients' arms and legs back on. Her speciality is nerve transplants. Using the nerves from corpses, she is able to give a paralysed toddler the use of her hand again, and help a 16-year-old who nearly lost his leg in a water-skiing accident ski again. I am sure if I had to face the choice between losing a limb and having a teeny nerve from a dead person sewn on, I would opt for the latter. Nevertheless, McKinnon's work does seem to smack of Dr Frankenstein's laboratory. She even has plans to remove the nerves from the recently deceased and bottle them until someone needs them. Where might this lead? To putting whole limbs in the freezer for future use, that's where. Even McKinnon admits the logical conclusion is hard to stomach. 'My work in the future might allow surgeons to transplant hands, arms and legs from dead bodies'. After that, we get the chance to see what the producers of the new flop, The Avengers, spent all the money on in Welcome to Avengerland (Pearl, 9.05pm) - because it certainly wasn't the script. This is easily the worst special-effects movie to come out of the major studios in years, and it also shows that the recent predilection for casting American actresses as Brits must end. Uma Thurman has many qualities, but Emma Peel she is not.
