The Pixar sequel "Finding Dory" led the box office for the third straight weekend, dwarfing "The Legend of Tarzan" and Steven Spielberg's Roald Dahl adaption "The BFG," both big-budget debuts that had hoped to dominate the July 4th holiday.
Dory earned $41.9 million from 4,305 theaters for the three-day weekend, putting its Friday-Monday gross north of $50 million.
