It’s something they’ve seen before, consciously or subconsciously.

So I bled that into the storyline, even though it’s a thousand years from now.

It’s gone full circle in a way.

Villeneuve has compared Idaho to a samuraiin interviews with EW, and Struthers says the parallel was intentional.

So they just keep coming and coming.

He is the alpha of his fighting style."

“That’s just a personal thing.

Some people don’t care.

That’s a big thing.

Struthers continues, “It’s very much a win-win for cinema.

Or things like that.
