On October 20, 2021, the Kamen Rider Winter Film website as well as its official twitter announced the title of the film, Kamen Rider: Beyond Generations. They made it an effort to replicate as much they could with current technology so that it doesn't feel as poor or parodic.ĭue to the large roster of Riders from both representing series as well as the franchise as whole, it was difficult to fit all the Riders in one scene, so the movie features the Riders traveling around the world, allowing each Rider enough spotlight to fight. The producers felt that it was strange trying to rebuild an old set using new materials in a new era, though ultimately the scene would be integral within the history of Kamen Rider.

While rebuilding Shocker's hideout, there were practically no materials other than old images at time to work with while attempting to do so. Rather than trying to explore the past, Mouri wanted to explore the future instead and introduced Century, a Rider from 50 years into the future, allowing the audience a glimpse of what was to come in the franchise. WritingĪs the film is a Movie War between Revice and Saber, both shows' respective themes such as family and keeping promises would be present in the film, portrayed through the relationship of the Momose father-son duo, as well as Maito Fujioka's casting as the younger self of his father's iconic role.ĭue to the film also releasing during the same year as Saber + Zenkaiger: Superhero Senki, which was also written by Mouri, it was important for him to be able to differentiate both films while ensuring that the spirit of Revice stayed true with the viewers of both the film and the TV series. On December 22, 2020, it was announced by producer Shinichiro Shirakura that a large-scale project would launch to commemorate the franchise's 50th Anniversary, with a new Winter film at the time "still in a blank state" but will premiere in the Winter of 2021.
