|They - that is a Finnish company, WoodpeckerFilms, making short commercial movies for a lot of customers - made a short that was sent to all their customers as a Christmas gift. I believe that was in year 2003. It leaked out to the internet, and made a huge hit.
The short made such a success that the company decided to make a full length feature film, released 2010. The final highlight is closely related to that of the short, but the story leading up to it is certainly quite different.
I do enjoy the short, but the real Christmas story comes in the full length feature film.
If you buy it on CD/DVD, there are a couple of supplementary shorts. Fair enough, but the two of significance are the 2003 short and the 2010 full length feature movie.
