How did you create the original stories for the theatrical movies?
When we made the episodes for the theatrical features, first the scriptwriter, the producer, and Toriyama-sensei‘s supervising editor would get together, and meet about story concepts, such as what to do about the main villain. Then I would put together a plot based on the content of what we’d talked about. I’d send that plot to Toriyama-sensei and get his opinion on it, then start writing out the scenario — that was the typical flow. Once I got to writing, I’d be joined at the hip with the producer.
With regards to the contents, there was the restriction that the movie “not progress into story settings further ahead than the TV anime at the time of its premiere”; for example, even if I’d decided to do fusion, I wouldn’t be allowed to do it ahead of the TV anime or the original manga.1 So I’d always be conscious of its state of progress on TV, and if we were doing the Freeza arc in the TV anime at the time of the premiere, a story would be born with the sense of, “Let’s bring out Freeza’s older brother!” Except, at times such as when the state of production on the TV anime caught up to the original work, it would be extremely tough with nothing to use as hints, and I received ideas directly from Toriyama-sensei.
It would take about three months’ time from the planning stage until the completion of a single movie’s scenario. Dragon Ball Z had two movies shown each year, in spring and summer, so that works out to me having been writing a theatrical movie scenario for over half a given year at the time. (laughs)
