When Pixar was bought out by Disney, I among many others were worried that like so many takeovers, the larger less creative company will absorb the smaller one and thus break up the team and thought process and kill all the skills and talent they had. However Disney did a great thing, they pretty much let Pixar do it’s own thing like they did before, and it’s treated them well because they’ve come out with some great movies since then.
However, I wanted to state how Pixar was awesome, because even after Wall-E was made and ready to ship out Pixar made a few extras including a short which introduced us to BURN-E. Whether it was intentional marketing move, or whether some employees were just playing around with the renderfarm I don’t know. The fact that they actually made additional content just for the release is awesome. It’s a shame you don’t see that more often, and it’s one way to tell that Pixar is going to be around for quite some time.
