I picked up a copy of "The Dark Knight" special edition on Blu-Ray tonight, and as I was watching the special features they were showing Hans Zimmer in his studio recording the Joker theme for the movie soundtrack.
At one point they cut to a scene of him working with a cellist, and low and behold, you see the back panel of a Virus TI Polar in the background! So, I'm putting in a shout-out for Hans Zimmer - he has a Virus TI Polar.
