Six films with John Pitman 5: Steve Davis
At 23, STEVE davis, the World Snooker Champion, has realised his boyhood ambition of finding fame from the sport he loves. He plays for the glory not the money. But now that television has turned the top boys into superstars, he's already on the way to becoming snooker's first millionaire. Davis has been groomed and packaged by an astute manager, Barry Hearn - known in the business as Barry 'Earn because ' we never do anything cheap for Steve Davis. ' Hearn has come in for some criticism. ' People say I'm overworking him. Maybe it would be like that for a normal player, but not Steve because he's not normal. He's totally dedicated to the job and we're having so much fun we're frightened to go to sleep in case we miss something.'

- Thailand's Market in Children
Every year thousands of children from the poor provinces of Thailand take a one-way ticket to Hualampong station, the gateway to the capital city, Bangkok. Many travel alone. Others are escorted by a relative or child-trader. All are looking for work. Some will never return home.
From the moment the children step off the overnight trains professional eyes are scrutinising them - deciding whether they are suitable for domestic service, sufficiently sturdy to work in a sweatshop or attractive enough to appeal to the patrons of a brothel. For Hualampong is the centre of a professionally operated market where children are bought and sold.
