Moomins and the Comet Chase (2010)
Moomins and the Comet Chase is a 2010 stop motion film compiled from the Comet in Moominland-based episodes of the 1977–1982 Moomins TV series animated at Se-ma-for in Poland, restored and re-soundtracked with multiple voice actors replacing the single narrator. It is the second such Moomin film produced by Finnish children's film company Filmkompaniet, the first being Moomin and Midsummer Madness, and the first one converted to stereoscopic 3-D. A similar revision of the remainder of the series for high-definition television of all 78 episodes will follow and is currently in production.
