Krysar (The Pied Piper) is a 55-minute film, almost all of it stop-motion animation. That's a total of 3,300 seconds, or 79,200 frames of film, each one a little different than the one before to give the illusion of motion. I've no idea how many person-hours of work went into this little gem, but it shows. The story line follows the fairy tale pretty much, except for the denouement. The sets look like they were made by the folks who did The Cabinet of Caligari and the people puppets have rather angular faces. A rather well-done film, although I found myself wondering if Czechoslovakia had a Society for the Prevention of Cruelty to Animals - some of the rats in the moat didn't look too happy.
