“Inside Out” delivered the firepower at the five-day holiday weekend box office as it finished in first ahead of “Jurassic World” and new entries “Terminator: Genisys” and “Magic Mike XXL.” In a tight race, Disney-Pixar’s animated comedy pulled in as estimated $45.3 million in the U.S. over the five days — giving it $246.2 million stateside in its third week at 4,158 locations. “Inside Out,” with Amy Poehler, Mindy Kaling and Bill Hader voicing the emotions of an 11-year-old girl, is showing impressive staying power at multiplexes.
