This is now the 5th Disney film this year to make $1 billion. The only other film this year to also hit a billion was Spider-Man, which was a movie made BY Disney FOR Sony. So, really, Disney had a hand in every billion dollar film so far this year, with at least 2 more (Frozen 2 and Star Wars) most likely still to come.
'Toy Story 4' Crosses $1 Billion, Fifth Disney Film to Hit Global Box Office Landmark in 2019
I think Frozen and Star Wars have potential to easily smash a billion.
