Dir: Don Sharp
Starring: Rod Steiger and Richard Johnson
After the death of his family during a riot in Belfast, an ex-IRA man comes up with a plan to blow up the British Houses of Parliament
The street battle scene supposedly set in Belfast was actually filmed in White Street, Southall, and a BR blue-liveried Class 117 suburban DMU is briefly glimpsed passing by in the background. There is also a later scene filmed on the concourse of London Waterloo station though no trains are visible.
