Many locations across
Glasgow (including the Victoria Infirmary) and the
Central Belt of Scotland were used in filming. Some parts were even filmed in Compston's home town of
Greenock.
Dunlop in East Ayrshire was also used for the home of the detective Muncie and the police station (outside entrance). Albion Automotive disused office in Scotstoun was used for scenes in the inside of the police station.
Culture Secretary,
Fiona Hyslop, confirmed that the
Scottish Government would be contributing
£250,000 towards the production. She announced this on the opening day at the
Edinburgh International Film Festival in June 2016. Both Compston and Henshall spent time researching their parts and the characters they would be playing. Compston admitted to being scared stiff in one scene and said that he had driven around to Manuel's old house after filming and parked up, "just to sit outside". The production caused controversy amongst the relatives of some of the victims. The production team tried to contact everyone, but Stuart and David Reid, whose two aunts, Marianne Watt and Margaret Brown and cousin, Vivienne (daughter of Marianne Watt) were killed by Manuel in 1956, could not be found. The brothers have said that the production would re-open old wounds. They contacted the production team who listened to their comments, but the brothers claim it was to no avail; “We asked ITV to scrap it. The producers did listen to what we had to say but by this point it was too little, too late. It was obvious they had no intention of pulling the plug.” ==References==
