Disney's re-entry into 2D w/ Princess and the Frog came up with around $27 million. It opened at #1, and despite it not having the totals of a Pixar movie, I'd have to bet that the execs at Disney are pleased.
The budget for this film was lower than the 3D films produced at either Pixar or Disney. So, $$ expectations are lower. While at first glance, it almost seems like a disappointment, the fact that it made back somewhere around half of its production costs in the opening weekend is a good sign.
I'll bet that Disney will greenlight another 2D film before too long.
