email@example.com Life Before Birds: Nature's Death Traps Pearl, 8pm Pearl is warming us up for its biggest documentary coup of the summer, Walking With Dinosaurs, which starts next week. Tonight, it repeats two documentaries that shed light on the prehistoric past. The first visits the ancient death traps, such as ice fields and swamps, that killed many an animal, and preserved them for future study. Without these fossils, the BBC would have faced much greater difficulty in making Walking With Dinosaurs, a natural history of these creatures that looks almost as real as any other wildlife film: the documentary-makers would have had far less idea as to what to base the computer models on. This is followed by Dinosaur Attack! (Pearl, 9pm), another repeat. Sixty years ago palaeontologist Roland T Bird stumbled upon one of the greatest dinosaur finds of the century. Bird believed his discovery of a dinosaur trackway, lined with hundreds of huge fossilised footprints, to be the perfect record of a dinosaur kill. No one believed him - until recently. Now, a sculptor and a professor use computer technology to illustrate how a nine-tonne dinosaur could jump on to the back of another beast, five times its size, and slaughter it. We'll be seeing many more graphic illustrations of this type of behaviour in coming weeks. Lost Years Of The Loggerheads National Geographic, 9pm When baby loggerhead turtles fight their way to the open ocean, they have just a one in 10,000 chance of surviving 10 years, to return to the same beach and lay their own eggs. A Portuguese biologist is trying to piece together what happens to these creatures in the intervening years. Understanding the many hazards they face may help save the species, he believes. In this programme, he embarks on his sea adventure, starting to unravel those lost years. Beware: Car Thieves At Work Pearl, 11pm Every 28 seconds in Britain, someone becomes the latest victim of car crime, said to be reaching epidemic proportions. Car-napping is the latest version of this crime, where victims are forced to pay a ransom to get their cars back, and the most likely victims are those attending hospitals or funerals. The makers of this film test the reaction of the public to car crime, by breaking into as many cars as possible within two hours, in a busy shopping street. The results are astonishing. Voices From A Locked Room HBO, 4.30pm Intriguing psychological drama based on the true story of the Jeckyll and Hyde life of 1930s British composer Peter Warlock and his most vocal critic, Philip Heseltine. Jeremy Northam (above) plays the two men. Heseltine has a whirlwind romance with American torch dancer Lily Buxton, the period when the feud between critic and composer reaches new heights. She wants it to end, but is stunned to discover the truth behind the conflict. Live A Little, Love A Little TCM, 9pm Elvis Presley has a tough time juggling two photographic jobs, one with a strict, conservative publishing house and the other with a pin-up magazine. But wherever he is, of course, he manages to hold in thrall a bevy of women (1968). This starts TCM's Elvis Rock-O-Rama, a salute to the rock 'n' roll king. Speedway (10.35pm), The Trouble With Girls (12.15am) and Girl Happy (1.55am) follow, for those who want to rock through the night.
