Starting with the one for the 17th Godzilla movie, "Godzilla vs. Biollante," published in December 2015, this book has become a series and has consistently featured Godzilla movies from the Heisei era. In 2021, following the third Godzilla film "King Kong vs. Godzilla," the first in the series to be published in the Showa era, the fourth "Mothra vs. Godzilla" and the fifth "Ghidorah, the Three-Headed Monster" were published in succession, and were well received by Godzilla fans. This time, we are pleased to feature "Invasion of Astro-Monster," a popular Godzilla movie in which Godzilla goes on a space rampage for the first time and Akira Ifukube's march from the same film is unforgettable. "Completion" series includes a number of snaps from TOHO Marketing's archives, selected color snaps, and gravure pages, three scenarios (a study draft, a preparatory draft, and a final draft), a project that explores the history of the production of the film, various interviews with the cast and crew that can be recorded in the current state of the film, data on the film, and a variety of other information about the film. The book also includes interviews with the cast and crew, data on the film, shooting schedules, location guides, props and props, and a column with trivia from the many writers who have written about Godzilla.
