This zany, eye-popping, knee-slapping landmark in combining animation with live-action ingeniously makes that uneasy combination itself (and the history of Hollywood) its subject. "Who Framed Roger Rabbit" is based on classic L.A. private-eye movies (and, specifically, "Chinatown"), with detective Eddie Valiant (Bob Hoskins) investigating a case involving adultery, blackmail, murder, and a fiendish plot to replace Los Angeles's once-famous Red Car public transportation system with the automobiles and freeways that would later make it the nation's smog capital. Of course, his sleuthing takes him back to the place he dreads: Toontown, the ghetto for cartoons that abuts Hollywood and that was the site of a tragic incident in Eddie's past. In addition to intermingling cartoon characters with live actors and locations, "Roger Rabbit" also brings together the greatest array of cartoon stars in the history of motion pictures, from a variety of studios (Disney, Warner Bros., MGM, Fleischer, Universal, and elsewhere): Betty Boop, Bugs Bunny, Mickey Mouse, Woody Woodpecker, Droopy Dog, and more! And, of course, there's Maroon Cartoon's greatest star, Roger Rabbit (voice by Charles Fleischer), who suspects his ultracurvaceous wife, Jessica Rabbit (voice by Kathleen Turner: "I'm not bad; I'm just drawn that way"), of infidelity. Directed by Robert Zemeckis ("Back to the Future", "Forrest Gump", "Contact"), not since the early Looney Tunes' "You Oughtta Be in Pictures" has there been anything like "Roger Rabbit".
