To be accurate, he says "Naturally, I'm sure that there are fans of the original work (i.e. the novel) and anime version who feel uneasy about [the live action series], but in the first place, it's not yet clear whether the series will be available for viewing in Japan at all, thus for now I hope that you'd keep an eye [on the news]."

So, he's not saying "not to fear", he's only saying that he's not yet sure if the Japanese audience will be able to watch it in the first place.
