I grew up with McCoy so I've always had a soft spot for his adventures. This is one of his more memorable screen outings, this time featuring an alien planet where the conceit is that sadness has been banned on pain of death. It's a bizarre concoction made even more bizarre by the introduction of a hulking robotic henchman villain modelled on Bertie Bassett, although sadly he remains stuck to the floor for most of the running time. Interest comes from the Thatcher-style totalitarian villain and the interesting actors, Ronald Fraser among them, while a wisecracking McCoy and spiky Aldred add to the mix.
