Yeah, Star Wreck is legally free and available. I reasoned that once you find out that, you will also find their next movie (which was commercially released, and is worth watching, too.)

The idea of Rare Exports is based on the notion that so many children initially are afraid of Santa Claus. So, there must be a hidden story, and the gut instinct of kids tell them to steer away from Santa... Also, they are playing with some aspects of Finnish tradition, it is not all just imagination of the film makers. In Finnish Santa Claus is called "Joulupukki", which means "The Christmas Buck" - which, thinking of it, sounds more like some sort of pagan demi-god =) There was a tradition of a group of young men dressing up as scary bucks, and after christmas they went from house to house, asking for booze. This tradition has been dead a long since, and I don't know the exact roots of it. But somehow this scary buck stuff is connected to christmas tradition in Finland =)
