Last season Nottinghamshire beat Worcestershire in July. After that Worcestershire did not lose another John Player League match. Worcestershire finished runners-up in the League. That defeat by Nottinghamshire could have cost them £1,000 in prize money. To win a one-day competition, every match is for the major prize.

'The White Man is Coming'

It's the eleventh hour for the tribes of Brazil's Xingu River... Orlando and Claudio Villas Boas have protected the Indians in the jungles of the Mato Grosso for 34 years. Now the Villas Boas are retiring; age and tropical illnesses are forcing them to give up. They have no successors. This film looks at the endangered way of life of the Indian tribes along the Xingu: the Suya, the Txucarramae, once the most feared tribe of the Amazon, and the Kreen-Akrore, subject of the award-winning The Tribe that Hides from Man.

Claudio Villas Boas makes a last return visit to Diauarum in the Xingu Park - and tells the Suya and the Kreen-Akrore, 'This is your land; if the white man comes... you must send him away with bows and arrows...'

'Most of one's life,' said Aldous Huxley, 'is one prolonged effort to prevent oneself thinking.'

The story of a working-class family in East London during 1939 and 1940; a family destroyed by the ordeal of nightly bombing, of air-raid shelters and domestic tragedy. Filmed entirely on location, No Hard Feelings is a brilliant evocation of London during the Blitz.
