The new Disney Pixar movie for 2009 is no science-fiction. But the movie Up still looks appealing.
Have a look to the second trailer of Up from Pixar:
The old widow is named Carl Fredricksen. He was wasting his last days in boredom... That is to say until Russell the fatty boy went up for a visit, starting point of a crazy adventure.
Such a human-centered theme is rather surprising from Pixar, maybe they're feeling more confident by now, or it could be some influence from Disney.
Anyway, I bet Up will be the usual Pixar success that will amaze us all!
