Kids love him. TV execs adore him. Sheesh, it's enough to make out-of-work kiddie-show host Rainbow Randolph puke purple. Ever since that plush, fuchsia-hued, platitude-spouting Smoochy the Rhino started Jiggy-Ziggy-dancing in Randolph's time slot, he has just one mad goal: turn the rhino into a dead duck. Danny DeVito (It's Always Sunny in Philadelphia, Twins, Matilda) takes the rhino by the horn to direct and co-star in this gleefully twisted skewering of children's TV. Robin Williams (Insomnia, Jumanji, Mrs. Doubtfire, Good Will Hunting), his famed wit set at warp, plays ranting Randolph. Edward Norton (Fight Club, Glass Onion) is the high-minded goodnik whose righteous-rhino creation becomes a sensation, and Catherine Keener (The 40-Year-Old Virgin, Get Out) portrays a jaded exec who likes kid-show hosts in, let's say, a grown-up way. Say nite-nite, rhino!
