Le martien de Noël (1971) on Netflix

Plot summary

During the Christmas season a martian comes down near a town in northern Quebec and steps out wearing a long fur coat and something resembling a net ski mask. He wanders the snowy streets blowing bubbles and taking sweets from the grocery store, and the locals grow suspicious. Frankie and Cathy, two siblings walking home from the store in snowshoes, try to understand what they have just seen. They come across his flying saucer and climb aboard, wary at first. The martian gives them candy and tells them his craft has broken down. The children want a trip around the world, and in return they will help get it flying again.
