True Grit is no longer the only Western at the box office. Paramount this weekend is debuting Rango , a Western with a difference. First of all, it's the first one in memory to be animated. Second, the hero is a chameleon. Third, he's voiced by Johnny Depp. Fourth, it cost $150 million to make, making it perhaps the most expensive Western ever produced. And fifth, it's the first animated feature from George Lucas's effects house, Industrial Light & Magic. Box-office forecasters expect the movie, which is receiving overwhelmingly positive reviews, to earn about $45-50 million. It faces modest competition from Universal's The Adjustment Bureau , starring Matt Damon and Emily Blunt, which is expected to earn around $18-22 million. Two also-rans are also running Relativity Media's comedy Take Me Home Tonight and CBS Films's Beastly, neither of which is expected to crack $10 million.
