Naruto Shippuden the Movie: The Lost Tower

Naruto Shippuden the Movie: The Will of Fire
What they share
Both films are directed by Masahiko Murata, and they both carry the foreign gem, playful mood tags, and they sit in Action / Adventure / Animation territory. If that's the register that drew you to Naruto Shippuden the Movie: The Lost Tower, the second film will land in a comparable space — through a different lens.
What Naruto Shippuden the Movie: The Will of Fire is
Here's a film that asks, "What if ninjas... went missing?" The missing are all kekkei genkai users, and suspicion falls on the Hidden Leaf Village. Naruto must then battle to stop his mentor Kakashi from sacrificing himself to avert a ninja war. It does offer a lot of ninja action.
