The adaptation of Roald Dahl's beloved children's book boasted a production budget of $140 million, making its performance this weekend nothing short of a major flop for the studio.Meanwhile, Pixar's Finding Dory held strong in first place for yet another week , earning $41.9 million. Just behind in second place was The Legend of Tarzan, which debuted to $38.1 million.While it exceeded expectations, Variety notes The Legend of Tarzan cost $180 million to produce, so Warner Bros. will have to depend on foreign performance before determining whether or not it was a successful endeavor.This weekend also brought with it the debut of The Purge: Election Year, which had a successful opening for Universal, making $30.9 million off its modest $10 million budget. While it didn't manage to eclipse the original film's $34.1 million figure, the series' third installment did surpass The Purge: Anarchy's $29.8 million opening haul.Rounding out the top five was Independence Day: Resurgence, which earned just $16.5 million after its underwhelming debut last weekend.Here are this weekend's Top 10 domestic box office estimates via comScore
