The movie is set after episode 493.
Appropriately they hired Tsuneo Kobayashi known for directing romantic anime as the film's director.
Only a pep talk from Sakura about the unwavering love and devotion Hinata has had for him for years—which is identical to Sakura's own love and devotion for Sasuke—does he snap out of it.
Luckily, has that in spades for Naruto.
Then Naruto asks Hinata to grab a hold of him as he says he wants to fly above and be with him as he uses a Rasengan to break him out of the dry spring cave.
It starts when he goes to the Tenseigan Core orb only to find it destroyed by Naruto and Hinata, His composure starts to crumble but its not until after he loses his fight against Naruto, and Hinata reclaiming Hanabi's stolen eyes that he completely loses it and becomes unhinged.
