One tradition of CES keynote addresses is bringing in "guest stars" to help promote certain strategic initiatives or new franchises. Sir Howard Stringer's CES keynote on Wednesday included Jeffrey Katzenberg of DreamWorks Animation and John Lasseter, the creative head of Disney and Pixar animation.

Katzenberg was there to plug 3-D in the cinema, and show a clip from DreamWorks Animation's forthcoming "Monsters vs. Aliens" that featured a 50-foot woman and the destruction of the Golden Gate Bridge. (Sony makes cameras often used in 3-D production, and its 4K digital cinema projectors are just starting to be used in theaters to project 3-D content.) Katzenberg said there have been two important technological revolutions in the cinema so far -- sound and color -- and that 3-D would be the third. Here's the audio of his appearance...



Lasseter's job was to emphasize how important Blu-ray discs are to Disney and Pixar, allowing the audience to appreciate each precious pixel of their animators' digital artwork. He also mentioned that Blu-ray discs might soon be a way of distributing 3-D titles to the home.
