- When Mervyn Johns is waiting in the bookshop he stands by a photograph of a nude in the magazine L'Art Catalan. The girl in the picture is hardly Catalan, and it is surprising the censor passed it. Also when the stripper comes down the stairs during the performance, she passes a large silhouette of a nude. The censor was clearly asleep.
- 温斯顿·丘吉尔 wanted to ban this film because he considered that it would demoralize audiences.
- The War Office asked Ealing to make a feature length training film for them on the subject of security, but provided minimal funds. Ealing more than doubled the budget from their own resources, to produce a film whose appeal transcended its military function. The very large profits from commercial distribution went first to repay this outlay, then to the War Office rather than Ealing.
