Bloopers & Gaffes:

In the scene where there is an air-raid, Sergeant Major Bloomer (Windsor Davis' character) puts on his ear protectors then takes them off and in the next scene they are back on again so he takes them off again.

Take a look at Windsor Davies' uniform. The lanyard is on his right shoulder in the outdoor scenes but left shoulder on the indoor scenes.

Behind the Scenes:

Composer Eric Rogers declined to score Carry On England when the orchestra he usually worked with was cut back from 40 to 20 people, due to budget constraints.
