Obviously it's far too early for a Christmas movie. In my book it's far too early for a Christmas anything until mid-December and even then I really only mean overeating. I'll make an exception for two things however - lego, and *mince pies, which I'll happily eat on a rainy day in July.
Sufjan apparently couldn't even wait for it to get cold to share this random and bizarre Christmas video - probably because it's made of lego, and what could be more exciting than a video made of lego?? Unless he actually is Santa's helper and this is a behind the scenes video. Which I would believe of Sufjan - have you seen his website?
*For the non-English people who may read this, we don't actually eat pies made of mince as a dessert at Christmas.
