NEW YORK >> “The Legend of Tarzan” and “The BFG” were both dwarfed by “Finding Dory” over the July 4th weekend, as the Pixar sequel led the box office for the third straight weekend.

According to studio estimates Sunday, “Finding Dory” earned $41.9 million in North America. Disney is forecasting a four-day holiday haul of about $50 million.

Of the three debuts, “Tarzan” came the closest to dethroning “Dory” with $38.1 million. While that total was better than expected, it’s far from chest-thumping for a movie that cost $180 million to make.

The horror sequel “The Purge: Election Year” opened solidly with $30.9 million, in line with previous “Purge” installments.

The continued success of “Dory,” however, bit into the opening of Steven Spielberg’s Roald Dahl adaption. “The BFG” debuted weakly with $19.6 million.
