There are two versions of this feature - the original UK version & the dubbed version which has the Glaswegian accents softened (substantially) for what was the then US release. This is the dubbed version. The cost to dialogue dud the "international" version cost more than the features original total production & publicity costs. The original footage was shot on 16mm film stock "blown" to 35mm for the international release. The opening footage contains the screen caption which reads: "The action of this film takes place in a fictitious town called Glasgow. Any resemblance to any real town called Glasgow is purely coincidental." This is the only release of this feature on the laserdisc format & appears to have been pressed in very low numbers indeed.
