In our exclusive clip of Crunchyroll and VRV‘s upcoming Dr. Stone documentary showcases anime director Iino Shinya and producer Katagiri Shusuke discussing the challenges of adapting Riichiro Inagaki’s critically acclaimed manga.

Because the show is being adapted from such an introspective series, capturing the constant jumps from the series’ technological past to its petrified present day tends to flow better in the manga than an anime format. According to them, the challenge lies in making moments that showcase a past that looks like our present-day and a future that looks like the stone age translate as well as it does in the comic.

The upcoming Dr. Stone documentary was shot in Japan alongside the creators of the series and is slated to hit Crunchyroll/VRV September 13 at 1 pm PT.
