Uchu Sentai Kyuranger VS. Zyuohger

Uchu Sentai Kyuranger VS. Zyuohger susposedly to be release in spring 2018, but it got scrapped.

Why It Was Cancelled

1. Tusk/Zyuoh Elephant's actor Tsurugi Watanabe was involved in a cycle accident at Nerima, Tokyo in November 2017.
2. Toei, the company behind Super Sentai, shifted focus to the next season, Kaito Sentai Lupinranger vs. Keisatsu Sentai Patranger, which was airing during 2018. They likely prioritized the marketing and production efforts for the new team rather than continuing crossovers involving past series.
3. Crossover movies require extensive effects, costumes, and coordination across large casts, and the cost of producing such a movie with two back-to-back Sentai series might have exceeded Toei’s budget allocation for the year
