Kino is a great activity for Sunday afternoon or evening (combined, perhaps, with a Kino-inspired Tagesprogramm). Very easy to do.
What you need:
3-4 German movies (obviously)
TV + DVD player OR beamer + computer (that plays Region 2 DVDs) for each Ort
Tickets: there are (usually) several rolls of tickets in Liechtenstein/Schreibhausen
Popcorn (you can also get special popcorn Becher)
1. Set up the tech stuff in each area.
2. Decide how many villagers will fit at each place:
Oben im Gasthof: 40-50
Unten im Gasthof: 40
Max Kade Haus: 20
Note that there is no easy way to project a movie Unten im Gasthof. Everywhere else it's doable. These numbers are for projected movies from a beamer; obviously you'll want fewer if you are using a TV.
What to do:
Have each villager pick a movie at some point during the day. We've done this in a number of ways. You can open each window at Einbeck and sell a different movie at each one. Alternatively, one time we did a Tagesprogramm where the losing team got to pick their movie first, and so on.
Watch the movies. Done.
