Bullock gives The Heat top billing GETTING Sandra Bullock to walk the red carpet in Sydney for the premiere of The Heat helped push her buddy-cop movie with Melissa McCarthy into the top spot at the Australian box office. However school holidays across the country meant The Heat's $3.88 million over the weekend only just beat the little yellow minions of Despicable Me 2 at $3.763 million. Guillermo del Toro's monsters-vs-robots spectacular, Pacific Rim, also debuted at the weekend but only just scraped past the $3 million mark. Keeping the school holiday theme alive was Pixar's prequel Monsters University which stayed steady in fourth place after four weeks in cinemas, while Man of Steel plummeted from second to fifth place in its third week out. Johnny Depp's latest film, The Lone Ranger, fell three places to No.6 while Brad Pitt's zombie epic World War Z dropped two spots to seventh place. Epic, another animation for the holidays, fell from sixth to eighth place, while The Great Gatsby and The Internship also sank two places each to round out the Top Ten.
