THE ADVENTURES OF ROCKY AND BULLWINKLE - One of the few really entertaining releases of the summer, and of course, almost no one has seen it. In this update of the popular TV cartoon, director Des McAnuff and his screenwriters have a field day with the film's escalating series of verbal puns and visuals riffs, and there are enjoyable turns by the likes of Robert De Niro, Rene Russo (born to play Natasha), and Piper Pearbo. While the film's roster of guest stars yields little humor, and it doesn't hold a candle to the frenzied delirium of the TV show, there are numerous laugh-out-loud funny moments, and when you're not laughing, you're likely to be smiling.
