It was pointed out to me on theLogBook’s Facebook page that the music used is actually from The Girl With The Dragon Tattoo. That leads to one of two possibilities:
1. The TGWTDT music is heard here as a temp track to be replaced (along with the craptastic lo-fi text effects) in the final edit.
2. The whole thing’s a fanedit (but where/how did they get the footage?).
I’m sticking with theory #1 – temp tracking is the bane of many a composer’s existence, and it happens a lot. Or maybe SyFy actually licensed the Trent Reznor music (which seems like it’d be a pricey proposition for a trailer).
