Shot on film, 'Machinegunner' was an eighty-minute play made by H.T.
Leonard Rossiter immortalized himself on British television as a stressed out executive (Reginald Perrin) and a mean-spirited landlord (Rigsby) so it's easy to forget he was no stranger to more serious roles, including '2001: A Space Odyssey'. Here he is again playing it (mostly) straight as an opportunist amateur detective / debt-collector, Cyril Dugdale.
