If you haven't seen Trent Reznor's Fringe promo, here it is. The promo features a reworking of the Nine Inch Nails song
Zero-Sum by Reznor, who goes on to recite lines of dialogue from William Bell (Leonard Nimoy) over the music. It also has a great upcoming line from Walter in it. Creepy and neat!
The folks over at Fringe have said Razor is welcome to come over and be on the show anytime, though he'll probably get his head blown off or something.
