I'm always curious how the script was written, the movie got made, how the CGI was done, etc. So when I buy a DVD I usually go for the special edition. The Batman Begins Sp. ed. DVD was especially good so I was really looking forward to the Dark Knight sp. ed. I assumed there'd be some insight/interviews etc. into Heath Ledger's performance, but there was nada. The only thing is a 17 min. doc on the fucking music score! Oh, and it has the 6 IMAX scenes in IMAX format--fat lotta good that does me w/out a fucking IMAX screen in my home. Thanks for jerking me out of an extra $10 Warner Bros! I usually wait until I catch a sale online and generally spend no more than $10-$15 for a NEW DVD, but I got TDK on an impulse buy.
That's strange that the WALL-E special ed. was lax on features though. Pixar usually goes all out on the special editions. I love the movie, but haven't got it on DVD yet.
