From the NY Post:

The movie version of "SpongeBob," Nick's top-rated kid's show, will likely hit theaters in late 2003 or early 2004 and will be produced by Paramount, sources say.

Details are sketchy at this point, but there's a chance that SpongeBob and his pals could even leave the safe environs of their underwater home, Bikini Bottom - and venture elsewhere during the course of the movie.
