After some rather lackluster -- for it -- openings of late, Disney's Pixar came roaring back with Monsters University over the weekend. Its $82.43-million debut was the animation studio's second-biggest ever, behind only Toy Story 3, which opened with $110.31 million in 2010. It also marked an unbroken streak of 14 No. 1 openings for a Pixar feature, beginning in 1995 with the original Toy Story. Hollywood.com box-office analyst Paul Dergarabedian noted that the movie went into the record books in second place (behind Toy Story 3) under three other headings: highest June animation opening; highest June opening in Disney history; and highest Pixar opening. Coming in second was Paramount's World War Z, which performed far better than analysts had predicted. With $66.41 million in ticket sales, it ranks as the biggest opening for a film starring Brad Pitt. (Previous high for Pitt was Mr. and Mrs. Smith, which opened with $50.34 million.) Dropping steeply (65 percent) to third place was Warner Bros.' Man of Steel with $41.29 million, bringing its 11-day total to $210.08 million.
