Easter egg: Mess around with your remote controls, until you highlight the W with the 214 value underneath. You will be greeted with a old title test from Summer of 2004, in which was used to pitch the original plot and script for W.A.L.-E (WALL-E).
Easter egg: On the regular DVD (not the special 2 disc edition), go down to Special Features, press the left arrow then press the up arrow and it will highlight the B and L logo in the upper left hand corner of the screen. It will take you to "Geek-o-rama", a feature about the Pixar employees.
Easter egg: On disc 2 (bonus disc) of the Special Edition set, at the bottom center of the Behind the Scenes menu (you get to it from the Humans main menu) is a link to the Original Development Test clip. I could only get to it from my computer, not my DVD player.
Easter egg: On disc 1 of the Special Edition set (the feature movie), on the main menu, the circle with the W and the 214 value (which changes) is a link to a short animation test clip. (I could only get to it on my computer, not my DVD player).
Easter egg: On the regular version of the DVD, on the Main Menu screen, go down to Set Up. Push the right arrow then the up arrow and it will highlight a W above the menu. It will take you to a test title from 2004 that the director used to pitch the movie.
