(smartplaylist) as taken from the National Film Registry - Library of Congress. NFR aesthetically significant films

I take no responsibility for the accuracy, but it seems to work. I simplified the listing by excluded dates, colons, odd foreign characters, and if your movie name doesn't match the title, you'll have to edit your movie title or the listing in the smart playlist for it to show up. Feel free to edit or improve, and if you do re-post with links. https://en.wikipedia.org/wiki/National_Film_Registry

Save this as "NFR.xsp" with your favourite editor (UTF-8 format) and place it in the Userdata (wiki) folder playlists/video, enter Kodi and select the listing in smart playlists. Obviously if you don't have the movie in your personal library, it isn't going to show up; on the other hand if you have multiple movies with the same name, this will inflate the number.
