Ministry of Mayhem was technically a Foundation/Carlton co-production, The Foundation basically being what emerged from TVS's kids department. Effectively the same team who made Number 73, Motormouth and What's Up Doc.
Indeed, and they had a similar feel as well, Ministry of Mayhem very much felt like What's Up Doc revisited (though the fact some of the cast were in both obviously helped). I remember reading Chris Bellinger was involved behind the scenes at Ministry of Mayhem although it seemed to have very little in common with the shows he was most famous for at the Beeb.
I remember that and thought it looked a bit odd, Granada for LWT. I also seem to remember it and its then on-screen sister Crossroads was described by one TV critic as "one [programme] is made by people who don't want to make soaps and the other is made by people who don't know how to make soaps".
Yeah, they weren't very good, but one of the problems with both those shows is that they were so late on screen. The idea of getting rid of Home and Away and replacing it with a British show was fair enough, but they should have had Home and Away finishing on Friday and Crossroads and Night and Day replacing it on Monday. But it didn't, there was nearly a year's gap, so all the Home and Away viewers had already gone off elsewhere and they had to start from scratch.
As we know, Night and Day ran three days a week with an omnibus (with added rude bits) after ten o'clock on Thursday, but they dropped the teatime showing after six months and then only did the omnibus, which got later and later and later, so by the end it was going out around 1am, surely the most expensive programme ever transmitted at that time.
