Bloopers & Gaffes:

As Sid James and his villains drive into Finisham Hospital car park in their Ford Zodiac, it can be clearly seen that the car has two normal windscreen wipers. However, when you see a view of them sitting in the car after it has stopped, the windscreen wipers are nowhere to be seen, only the stalks where the wipers should be are visible.

In the scene when Charles Hawtrey & Hattie Jacques are sitting down to watch 'The Surgeon', they have a drink before, he appears to pour only one drink and yet they both have full glasses afterwards.
s Blunt. The background chatter is repeated over and over again throughout the entire dinner scene.
