Ryûsuke Hamaguchi and Virginie Efira on All of a Sudden

I think I might ask you to start by telling us about the source material.

It's really no end adaptation, but the film is inspired by a book.

So perhaps you could tell us a little bit about the

book.

Thank you for watching.

First of all, thank you all for watching the film.

As you see at the end of the film as well, during the credits that this book is based on a book.

It is a exchange of letters between Makiko Miyano and Maho Isono, a philosopher and a culture anthropologist.

But the philosopher, Makiko Miyano, also has cancer.

And in the 10 exchanges that happened between the two of them, halfway through, Makiko Miyano really does take a sudden turn for the worse.

And through the exchanges, you really see that they go beyond a relationship between two academics and really see them come together.

And I was introduced to the book through my producer, Hiroko Matsuda, who is here today.

And I really wanted to make sure that I can bring how much I was moved by the book into the film.

And so that's how I really worked.

But again, it is an adaptation.

However, it is quite different.

What you see in the film is quite different from what is in the book.

I do hear there is a translation coming out, so I hope you are able to actually compare later on.

I'm interested in this process of just translating this book that, as you say, is an exchange between two scholars.

So it really is a book of ideas.

And I'm interested in how you think about giving cinematic form

to ideas.

That's a really difficult question.

What I did was to discover some movement.

Yeah, I do think that this is a very difficult issue, but what I ultimately did was to really try to discover the movements that were happening.
