When the evil forces of STENCH strike at a British research laboratory they get away with a top secret chemical formula. With the British agents spread thin across the world, The Chief has very few options open to him to follow up the lead into the mysterious Milchmann who led the attack. The Chief scraps the bottom of the barrel and comes up with Simkins probably one of his worst agents. Assigning Simkins with a handful of trainee agents Crump, Honeybutt and Bind the ragtag band set off to meet up with Agent Carstairs in Vienna.
Despite being made in the mid-sixties this Carry On film has more in common with those made early in the series (Teacher and Sergeant) more than it does with those made around the same time as it (Jack, Cruising, Cowboy). It is not just the black and white that made me think this but also the fact that the humour seems fresher and slicker than the heavy innuendo and crudity of the later films. Others have said this has more in common with Ealing than Carry On they are wrong, but I can see what they mean because the light spy spoof is very much an early Carry On. The material isn't great though but it does produce easy and obvious comedy and those looking to just to fill a wet Sunday afternoon.
The cast make a big difference even though not all the regulars are present. Williams and Hawtrey are the most fun as both play up their camp characters to good effect they both get the best lines as well. Windsor is pretty good as she isn't just used as an object. Cribbins was pretty dull I thought but Dale was good value in a small role. Additional support from Barker, Laye and a few others all helps. Overall a Carry On like they first made them; not brilliant but light fun.
