'Clubland was turning into gang-land. People were frightened. The police were nervous. Was the Mafia moving in?' - Tyneside, 1966
The second of two documentary films which investigate the murder of Angus Sibbet, a gaming-machine collector who was shot dead in the Durham mining village of South lletton, in the New Year of 1967. Two men were convicted: Dennis Stafford and Michael Luvaglio, both leading figures in the clubland scene of Tyneside in the mid-60s. They have been released from prison recently and have been talking to Stuart Prebble.

Ten films in which Magnus Magnusson explores the Viking World.
"Never was it thought such an inroad from the sea could be made." (Alcuin of York, 793)
The ship was the true symbol and spirit of the Vikings: nothing has yet surpassed the elegance and beauty of its lines, deceptively disguising its power and versatility. The Viking mastery of all the seafaring arts gave them the instrument not only of terror but of trade and colonisation.
In 793 unexpected assaults by sea-borne warriors from the remote fastnesses of Norway introduced the peaceful monastic communities of the north of England to the awesome terror of lightning attacks from the sea. Magnus Magnusson describes this 'bolt from the blue' and shows how even the mastery of Norway itself depended upon sea power - the age of the Vikings had begun. With Colin Blakely, Daniel Massey, John Bennett
