I use short films all the time in class. It's hard to justify spending 2-3 full class periods watching a feature length film. Shorts pack a lot of discussion bang for their time buck. This website has a great compilation across genres. Great for world language classrooms, prompting creative writing, documentaries on a plethora of topics, and more.
Really good ideas for decorating a foreign language classroom. I love the idea of rewarding students who finish early with a trip to France (area where they can hang out/ play games/read children's books in French). Maybe they could go to Le Café!
