The tidal wave of Finding Dory overwhelmed the Independence Day sequel at the US box office.
In its second week, Pixar's sequel to 2003´s Finding Nemo - featuring the voice of Ellen DeGeneres as the forgetful blue fish - easily remained on top with an estimated $73.2 million (£53.4 million).
That figure far surpassed the $41.6 million (£30.4 million) opening of Independence Day: Resurgence.
It debuted well behind its 1996 original, which opened with $50.2 million (£36.7 million), or about $77 million (£56.2 million) in inflation-adjusted dollars.
Elsewhere, Blake Lively's shark thriller The Shallows rode a wave of good reviews to a better-than-expected $16.7 million (£12.2 million) for Sony.
Matthew McConaughey's Civil War drama Free State Of Jones disappointed with just $7.7 million (£5.6 million), a blow to the upstart studio STX Entertainment.
