In this darkly comic yarn, Robin Williams is Rainbow Randolph, a conniving kids' TV show host whose career halts when he's involved in a bribery scandal. Squeaky-clean replacement Sheldon (Edward Norton), as lovable purple rhino Smoochy, becomes a media sensation, leading the manic Rainbow to try to defame-or kill-him, and Smoochy's manipulative agent (Danny DeVito) to make a deal with a gangster (Harvey Fierstein). With Catherine Keener, Jon Stewart. 109 min. Widescreen; Soundtrack: English.
