that best explain the 20th century. Acceding to popular demand for a film list, and I'm also interested in non-US fiction. Some commenters pointed to several - The Man Without Qualities, The Tin Drum, etc. - but I would be interested in other suggestions from around the world. Apologies for tying up VC with something unserious, but I actually need to compose a list for some high schoolers.
