Danny DeVito takes the rhino by the horn to direct and co-star in this gleefully twisted skewering of children's TV. Robin Williams, his famed wit set at warp, plays ranting Randolph. Edward Norton is the high minded goodnik whose righteous-rhino creation becomes a sensation, and Catherine Keener portrays a jaded exec who like kid show hosts in, let's say a grown up way. Say nite-nite, rhino!
