The combined powers of superheroes, the Pixar brand and a draught of family-friendly films helped Incredibles 2 become the best animated opening of all time, the biggest PG-rated launch ever and the 8th highest film launch overall. Disney estimated Sunday that the film earned $180m in its first weekend in North American theatres — far surpassing industry analysts’ loftiest expectations which had the film pegged for a $120 to $140m debut.
