Variola Vera (1982) - a hospital is quarantined during the outbreak of smallpox in Belgrade. One of the best disease films I've seen. Well crafted atmosphere of misery and dread, a healthy dose of body horror, detoriation of societal norms in the face of extreme circumstances, a nice ensemble of characters to root for or hate, and a fantastic soundtrack.
Der Fan (1982) - a teenager runs from home to meet her pop singer idol, things end up badly in a completely fucked up way. What makes it especially great is that shock value does not substitute conventional cinematic quality, but complements it. A hidden (?) gem.
