spy movies are a good idea! I know nothing about the source at the moment, but the list looks good; with at least some strong european entries. Not really much europsy-movies… but the greatness of them can be disputed 
looking for lists in subgenres is very welcome, to cater to fans that feel left out at some points now. next to spy movies i can think of, giallo, gothic horror, swashbuckling, peplum, fairytale, cyberpunk…(pinku, exploitation?, wuxia?)… the trick is finding solid sources. (I am going to look into this myself, but am kinda busy with the Imagine filmfestival at the moment)
