In total, Brad Bird's second "Incredibles" film has grossed $440 million domestically and $647 million worldwide, according to Box Office Mojo.

That makes "Incredibles 2" - which again stars the voices of Holly Hunter and Craig T. Nelson as the superhero parents - the second highest-grossing Pixar film ever in North America and the third biggest animated film ever, before adjusting for inflation.

The "Incredibles" sequel should soon pass 2016's "Finding Dory" ($486.3 million) as the biggest Pixar film and the biggest animated film.

Disney now has six of the seven highest-grossing animated movies ever in North America before adjusting for inflation; the only non-Disney film in the mix is DreamWorks Animation's "Shrek 2″ ($441.2 million).

Domestically, "Incredibles 2" is also the third biggest movie of the year, trailing only two other Disney superhero movies: "Black Panther" ($699.8 million) and "Avengers: Infinity War" ($672.5 million).
