This happens to be my favourite internet clip, the one I can watch again and again without ever getting tired of it. It is from Návštěvníci (The Visitors), a Czech Sci Fi television series from the early 1980s. While I have never been able to get my hands on a copy of the series with subtitles, this scene came to my attention because Jan Svankmejer , the Czech surrealist filmmaker who does wonderful things with stop-motion animation (his 1988 film Alice is one of the most chilling and original adaptations of Alice in Wonderland, just for your information), lends a hand with the special-effects. After watching it again this morning, I felt like sharing it with you. Sorry about the poor quality.
