LOS ANGELES (AP) – “Oz the Great and Powerful” is proving to be both – at least when it comes to movies this year. The Disney film is number one for the second straight week. It took in $42.2 million over the weekend. In a winter of movies that have underperformed at the box office, “Oz” is easily the biggest hit of the year. But overall, box office revenues are still down 13 percent from last year.
