I never understood the huge expectations for Mary Poppins when the remake of Cinderella, one of the most iconic princess and famous animation classic did "only" 550 M. I think Snow White, Cruelia, Dumbo, Pinocchio, The Lady and the tramp will do around these numbers (550-650 M, maybe a 700 peak). Alice was at the peak of the 3D age, the first live action of the recent series and with Johnny Depp and Tim Burton in their golden age as movie couple (the sequel was a flop!) while The jungle book is more an action movie and it was really an innovation for the special effects.
For the old school disneyan fables people have too much expectations, the children of their time are all almost dead after all 😂. The 90's classics like the little mermaid, the lion king and aladdin are the ones surely in the 1 Billion+ club. I always seen Mary Poppins with no more than 600 M worldwide.
