One of two movies shown at my elementary school. ‘Forbidden Planet’ the other.

Still remember them using the matches and cigarette for a fuse. If the day ever comes...

They were both great movies. Altira was really, really hot.

I don't remember that from "The Great Escape". It was, however, a key plot element in "Stalag 17" as the method Dunbar used to blow up the Nazi ammunition train.

Wow, all we saw were travel movies and I think one about the President’s.
Later in high school it was several
Gory safety movies in woodshop.

That trick doesn’t work with today’s cigarettes as there’s an additive that doesn’t allow them to continue burning without being smoked.
