Cinematoday had interviewed Shinichiro Shirakura today for the upcoming movie "Saber + Zenkaiger: Superhero Senki" and had said something that would point at Toei taking a different approach for Kamen Rider & Super Sentai Series from now.
It seems like Toei is always making a Hero Gathering Movie every now and then. But actually we haven't done it recently.
Shinichiro Shirakura laughs and reveals the reason for producing this movie by saying,
This year especially is Kamen Rider 50th Anniversary & Super Sentai 45 Works Commemoration year. It's a big milestone, so we felt that we have to do this. This might be the first & also the last time as Double Anniversary Movie. I felt the sense of mission and decide to make this.
All these years, the Super Sentai series have been celebrating their anniversary a year after the actual anniversary year to match up with Kamen Rider Series. The entry number was considered the milestone for it. For example, Zenkaiger is 45th Entry Work and not 45th Anniversary Work. Super Sentai Series began in 1975, so 2020 is the actual anniversary year. But Shinichiro Shikura had stated that this will change from now.
From now on we are planning to shift to the 'Anniversary' for Super Sentai Series, so Kamen Rider will get deviated from them. Due to this, this will be the last Kamen Rider & Super Sentai Crossover. Considering this as an oppurtunity, Super Sentai Series & Kamen Rider Series will get separated. We are thinking that they walk their separate ways in the future. This is considered as the starting point for it.
