The Australian Commonwealth Film Unit made several short public service films using sporting stars to promote road safety. This clip has tennis great Harry Hopman warning people to stay focussed when driving.
Hopman was the successful captain-coach of 22 Australian Davis Cup teams from 1939 to 1967. He worked with many of the greatest names in Australian men's tennis; Sedgeman, Laver, Rosewall, Fraser, Newcombe, Roche and others. He was, however, strongly opposed to players turning professional, even to the point of using his column in the Melbourne Herald to raise funds to buy a petrol station for Frank Sedgman's wife-to-be so he would remain playing as an amateur. It worked. For one more year at least.
His legacy is recognised in The Hopman Cup, an annual international hardcourt tennis tournament held in Perth.
