What makes this casting news interesting is that Arioka is a talent of the Johnny & Associates agency. The last time a talent from Johnny's was involved in a Tsuburaya production was with V6's Hiroshi Nagano who played Daigo Madoka/Ultraman Taiga.
A big screen adaptation of the original 1966 Ultraman series, the film will be written and produced by famed director Hideaki Anno (Neon Genesis Evangelion) with Shin Godzilla collaborator Shinji Higuchi (Gamera Trilogy) directing the said project. The first draft of the film was finished last February 5th with Anno fully joining the project after finishing the Evangelion:3.0+1.0 film. Distributed by Toho, Shin Ultraman is set for a 2021 release.
