I'll be blown away if the top film on the Letterboxd list doesn't end up being a James Bond movie.

A couple of things about this list:

Governments and governments' secrets are a biggie here, but they're not the only types of spies I'm including.

I'm only including one Bond film on this list. Sorry, but I wanted to make this as tight as possible to keep it from becoming a "Best Bond Movie" list. Same for the Bourne films. And the Austin Powers films. Actually, wow, there are a lot of Spies series aren't there? Just one movie per series on this list, basically.
