The Unstoppable Man is a 1960 British second feature[2] crime drama film directed by Terry Bishop and starring Cameron Mitchell, Harry H. Corbett, Marius Goring and Lois Maxwell.

[3] It was written by Bishop, Alun Falconer and Paddy Manning O'Brine based on the 1973 short story Amateur in Violence by Michael Gilbert.

Though in the familiar tradition of British second feature crime thrillers, it has the benefit of a Michael Gilbert story which, though unconvincing in some of its details, offers an intriguing exercise in detection.

The characters are sharply drawn, Terry Bishop's direction – apart from a slow middle section – is slick and resourceful, and the authentic backgrounds heighten impact.

Cameron Mitchell makes a strong impression as the businessman, while Marius Goring as the Inspector and Harry H. Corbett as the kidnapper give quieter but equally competent performances.
