Pixar Adds New Movie to Slate LAS VEGAS - If the pressure is on Pixar to prove that its creative spark remains intact after the critical crash that was "Cars 2," then the Disney-owned animation studio appears to be rising to the challenge. In a presentation to theater owners here on Monday, John Lasseter, Pixar's chief creative officer (and the director of "Cars 2"), said the studio has added a movie about the Mexican holiday Día de los Muertos to its slate. The film, which does not yet have a title or a release date, will be directed by Lee Unkrich, who won an Oscar for "Toy Story 3." Mr. Lasseter gave no additional details, but did show a colorful (early) logo with skulls and Mexican marigolds. Pixar likes to keep details of its upcoming movies close to its vest, partly because of competitive concerns; a typical Pixar film takes four years to complete. But Mr. Lasseter did dole out a few more morsels: a previously announced movie pondering what would happen if dinosaurs never became extinct got a title - "The Good Dinosaur" - and a release date of May 2014; and the next (still untitled) film from Pete Docter ("Up") will debut in June 2015 and will still take audiences on a journey inside the human mind as previously disclosed. As part of its presentation at the CinemaCon convention for theater owners, Pixar showed 30 minutes of its next feature, a princess movie called "Brave." Pixar has a lot riding on this movie, which arrives on June 22 and takes place in medieval Scotland. It is the studio's first film with a female protagonist (long, long overdue in the eyes of some critics) and first period adventure. The lush animation, particularly the central character's unruly shock of red hair, drew favorable buzz from the crowd, which included movie media. "Just watched the first 30 minutes of "Brave" at CinemaCon, and all I can say is wow," Eric Eisenberg, an editor at CinemaBlend.com, wrote on Twitter.
