I wouldn't so cocky with Disney box office this year. Domestically they will do fine but internationally it may be a problem. Warner Bros and Fox are being heavy hitters already making films based off Nostaglia like Independece Day, Ghostbusters, and all the other superhero films. Thanks to Wanda (AMC owners and the chinese company) merging with Legendary Universal has an even bigger upper hand when it comes to Warcraft and the other legendary films coming out this year.
Zootopia is safe as its the only mainstream kids movie for the next 14 days. The only other kid film that comes out that week is the beast and a boy but that's more a indie film and the kids film after it is the Little Prince by Paramount.
The Jungle Book is in a bad spot to be honest. It's between The Boss which comes out the week before and Barbershop 3. The Jungle Book may be Disney and such however due to the lack of animation may leave kids less desirable to go see that and more adults and teens to go so other films such as The Boss and more minority based crowds will go to Barber Shop 3. I also think the huge surprise may also go to the film Hardcore Henry with the gimmick of being the 1st POV mainstream action film and may have a paranormal activity size crowd and word of mouth that will pull from the jungle book.
Born in China is a documentary about Pandas. I doubt it will be successful against The Huntsman: Winter's War.
Captain America: Civil War is completely safe with no competition from the weak before or the week after. The only film it has going up against it is Going in Style.
Alice through the looking glass will flop and probably flop hard as it is up against X-men:apocalypse, Angry Birds from the week before, and Neighbors 2 from the week before and likely won't gain traction as summer blockbuster season starts the following week.
Finding Dory may do great in first week but expect to see a drop come second week with Warcraft coming out. With the Chinese company Wanda funding that, don't be surprised. The nerds will come. Then its another disney film with the BFG coming out in the third week
BFG should be okay as long as Finding dory doesn't pull from its numbers but it is also 4th of July weekend. However with huge teen/adult films coming out such Independence Day: Resurgence, The Purge:Election Year, and the Legend of Tarzan may pull people from seeing it and the Secret Life of Pets comes a week after BFG comes out.
Pete's Dragon is a weird one because there is not information about it to predict hit/flop
Doctor Strange is a weird one but it is up against Dreamworks Trolls which will pull some families.
Moana is in the worst of all movie situations. It will be this year's the good dinosaur as You have Fantastic Beasts come out the weekend before, The Great Wall which is Universal/China's hollywood pet project and Bad Santa 2. Internationally Fantastic beasts will surpass Moana mostly because its Harry Potter.
Rogue Ones is Star Wars so it will do well.
