Many of the WWII films designed to disseminate information to the public are rather dry and haven't aged well. However, this dandy little film starring Will Hay is worth seeing and really gets the point across very well.
During WWII, the German incendiary bombs were a serious problem. You couldn't just put them out easily and if you didn't act quickly, the termite bombs would literally burn through floor after floor of flats...destroying them in the process. Hay plays a man who is supposed to deliver a speech to the public on dealing with this menace and he then talks through the correct steps--and you see them acted out. However, this is all straight out of the book and Will never really dealt with one of these bombs. So, moments later, when one of these bombs hits his home, he's not at all prepared...so Mother has to deal with it along with his wife...while Will mostly runs about like an idiot.
Clever, well written, informative and funny...
