Jack Black is still hoping for a “School of Rock” sequel. “I wish,” he told us during a DVD-release party for his film “Bernie” Monday at Merc Bar. “I tried really hard to get all the pieces together. I wouldn’t want to do it without the original writer and director, and we never all got together and saw eye-to-eye on what the script would be. It was not meant to be, unfortunately. But never say never.” He added that they were still planning a 10-year reunion for the 2003 movie — “We’re all going to get together for a party.”
