The internet has rediscovered the streaming service's mastercode list for a number of super-specific genres. First unveiled by What's on Netflix last year, the sections can be found by substituting one of the thousands of codes into the URL "http://www.netflix.com/browse/genre/(code number here)".
Looking for independent military movies? Try code 463. Eastern European movies? 5254.
Check out the full list of codes on What's on Netflix but be warned -- there are more than 20,000 to choose from.
