Andrew Stanton will be showcasing WALL-E at this year’s San Diego Comic-Con, with sound designer Ben Burtt. They will be in Hall H on Saturday the 28th of July from 2:15-4:00. The next Narnia film is also being showcased during that timeslot.
Do remember that some other folks from Pixar will be making a presentation the day before (hopefully announcing the shorts dvd). More information here.
