Unfortunately most "Carry on" movies are filled with obvious smutty humour that at its time was very risqué, but also very base and doesn't age well. However, this film it is toned down, but still hasn't aged well, and is not bad for a bit of retro fun. Unlike most other "CarryOn" films it also carried a political message disguised amongst the humour. That at the time British industry was suffering badly, and a large part of that being as a result of frivolous industrial action by the unions. Not a bad movie for a rainy Sunday afternoon when not much else is on.
