When Jurassic Park was coming out, I don't remember the trailers beginning with E.T. entering a movie theater, and, likewise, the commercials to Schindler's List didn't begin with Indiana Jones thoughtfully gazing into the distance as he recalled the atrocities of Nazi Germany. Besides not making any sense, it would have been completely unnecessary given the brand power inherent in the name Steven Spielberg. Similarly, I would have thought that after the huge success of Toy Story, Toy Story 2, A Bug's Life, Finding Nemo, The Incredibles Cars, and Ratatouille, the Pixar name would be enough of an endorsement without whipping out Buzz Lightyear and Woody for the Superbowl WALL-E commercial. I guess it's sort of cute in a "Wink-wink! Remember Toy Story?! That was us!" sort of way.
