What do the films How The Grinch Stole Christmas and Up have in common? Besides (despite?) featuring unapologetic curmudgeons as primary characters, they both represent accessibility landmarks: Grinch was the first commercially-released DVD to have a closed-captioned option, and Up is the first to have the audio-described (DVS) track available for sale on iTunes. Of course, you don’t have to be blind to appreciate the DVS version–it could find the same drive-time audience as audio books, which means there would be more DVS-only versions of movies available, which would benefit blind people…yeah, we could live with that.
Amended to add: apparently more careful research than mine (thank you, codeman) has raised doubts about Grinch; with luck, an equally befuddled future investigator will find clearer documentation for the historic value of Up.
