The first trailer for the movie, which opens in February, sets up the movie pretty nicely: Banderas has a magic book that can make any evil plan he has spring to life (magically), but the final page of the book is being guarded by SpongeBob (the same guy who lives in a pineapple under the sea). The otherwise idyllic world of Bikini Bottom has been thrown into chaos, so SpongeBob and his pals have to go to the human world to track down the stolen page and set things right.
What's nifty is that when the movie takes place underwater, it's traditional 2D animation (done by the talented animators at Korean studio Rough Draft), but when they're on land, it's live action and the characters are full, 3D computer generated creations. Sometimes this conceit is dicey, since sometimes two-dimensional characters are better in, well, two dimensions, but these characters seem to have been transitioned with a lot of nuance and care and the whole thing gives off the vibe of that "Simpsons" episode where Homer slips through a wormhole and into our world. (Classic!) Also, at some point, they become superheroes, which is always fun.
"SpongeBob Movie: Sponge Out of Water" opens on February 6th, 2015, occupying that sweet, mid-winter release date that "The Lego Movie" owned this year.
