U.S. & World
Comic book companies, like record labels, have found that the death of a big star is great for sales. When Superman was killed by Doomsday in 1992, DC saw a Cobain-like surge in sales, and the issue was the best-selling in franchise history. However, unlike Biggie Smalls (but very much like Tupac) the character was resurrected. Captain America saw a similar bump after a sniper shot him down in New York last year.
From the sound of things, it seems like the Dark Knight is really in for it in the Batman Comic that comes out tomorrow. At least this will explain the lines outside Forbidden Planet. Stay tuned. Same bat time; same bat channel.
