1: The
Congo Michael Wood , long fascinated by the Congo, travels to
Kinshasa - capital of Zaire - for a voyage up river. He begins on the Colonel Kokolo, a floating town with 1,500 passengers crammed into rusty barges for 1,000 miles. At the Equator he takes a tramp steamer for Kisangani, formerly
Stanleyville. Finally he hitches a ride on the mission boat
Sarah, which carries him up the Lualaba River and on to the high savannah.
His view, from the decks of these working river-boats is very different from that of earlier travellers to 'the Dark Continent'.

In which Alec Clifton-Taylor, with his unrivalled enthusiasm for buildings, takes a discerning took at six of England's historic towns.
The fishing town of Whitby, on the north-east coast, clings to the steep hillsides of the estuary of the River Esk. The bare, windswept top of the East Cliff is dominated by the haunting ruins of Whitby Abbey and the strange, squat tower of St Mary's Church. "But the interior is a thrill. Absolutely unforgettable. Not a work of art, but a most illuminating social document." Marine Parade has clearly seen better days, but there are things to gladden the heart: Corinthian porticos, Gibbs surrounds, stepped keystones -echoes of the former glory of these once-fine houses. "And, joy of joys, there are no highrise buildings anywhere. There can be very few English towns that have managed to retain their 19th-century character so completely as this one."

A film about Andrei Sakharov It is 1957. Inside the secret heart of the Soviet Nuclear
Weapons Research Programme, a brilliant and successful young scientist begins to have doubts about the safety of atmospheric testing. So starts the dangerous and remarkable journey of Andrei Sakharov from the pinnacle of Russian society, through growing conflict with a menacing and inflexible bureaucracy, to disgrace and vilification at the hands of the State. The film ends in 1976 with Sakharov the moral leader of the new class of Soviet intelligentsia - the dissidents. Four years later he was to be banished to exile in Gorky where, subjected to increasing pressure from the authorities, he has remained to this day. A fine tribute (THE GUARDIAN)
A film of ideas and polemic (THE TIMES)
