 Two along a similar vein that immediately come to mind are:
In 
The Last Shot, Matthew Broderick plays a movie director hired to make a movie. Unknown to him, it is actually an FBI sting operation.
In 
The Man Who Knew Too Little, Bill Murray thinks he's participating in a a bit of theater playing out in the real streets but is actually involved in spy business.

				Wow, this is one of those movie plots that my father has mentioned to me a million times over the years but I've never heard referenced anywhere else.  You never cease to amaze, Alex.

 I'm curious as to how this would come up in conversation very often. 
It is an end-of-the-world movie worth seeing. A bit melodramatic (and Fred Astaire plays an Australian) but understated in good ways that modern end of the world never will be again.
