“Sitting Target”
Yes a B movie. Oliver Reed was not a great actor.
McVicar did better business. A few other 70s rough old gritty British movies are “Revenge” and “Scum” come to mind. Perhaps the best known is the original “Get Carter”
Everyone my age knows of the Hillman Avenger, the Ford Capri look-a-like. The terrible terrible rear black spots visibility. You hardly ever saw a model without dents on the bumper or the rear areas.
