A perfect marriage of material and studio, the silly antics of the popular kids book series “Captain Underpants” fits DreamWorks Animation’s cartoonish brand like a snug pair of boxer briefs. Captain Underpants: The First Epic Movie – starring the voices of Kevin Hart, Ed Helms, Jordan Peele, Kristen Schaal, Thomas Middleditch, and Nick Kroll as the evil Professor Poopypants – flies into multiplexes this summer right after school’s out: June 2, 2017.
