When Moomintroll learns that a comet will be passing by, he and his friend Sniff travel to the Observatory on the Lonely Mountains to consult the Professors. Along the way, they have many adventures, but the greatest adventure of all awaits them when they learn that the comet is headed straight for their beloved Moominvalley.

The story is based on the novel of the same name by Finnish illustrator and writer Tove Jansson. The original Comet in Moominland (Japanese-Finnish- Dutch production from 1992) was created and produced by Dennis Livson, whose son Tim Livson (Kindernet Entertainment), has now co-produced the new film with Cinematic Animation. While keeping the classical hand-drawn cel animation style by director Hiroshi Saito, animator Yasuhiro Nakura and writer Akira Miyazaki, the remastered film is updated for today’s 4K cinema standards, with new music, songs and dialogue.
