Distributors are wary of the title, but McGregor defends it with a passion.

I love it, he says.

I think it can mean whatever the viewer wants it to mean.

I love mysterious, poetic titles.

I was very impressed with that, and I was very moved by the script.

That being said, the characters in the film are notentirelyours, and the storyline is invented.

This isnt an event that happened, but its loosely based around our experience.

And its changed us because it was an amazing thing for Clara to ask me to do.

It was an amazing experience to do together, and it was just wonderful to have that time together.

Clara, you came on board first?EM:She wrote it.

I mean, she created it.CLARA MCGREGOR:Yeah.

Im a producer on it.

It was just us writing a script.

Has it changed your relationship in any way?

Its a very intense movie…EM:I think, yeah, in a positive way.

It was really bonding.

So, it was very special to spend that time putting ourselves into those scenes.

[Laughs] It wasnt like that.

But, at the same time, you cant go through something like this without it touching you.

I was just a very proud dad every day.

What kind of director is Emma Westenberg?CM:Emmas amazing.

She was just great on set.

But there was also a lightness to the days with her.EM:Shes an artist, yknow?

I feel like shes really an artist and she has an absolute style of her own.

She has a courage, um, and a lightness, which is, which is really exciting.

I mean, look at her choice of DoP, Christopher Ripley.

This is his first movie.

And so the film feels very new and original.

Ewan, when did you realize your daughter wanted to act?EM:I dont really remember.

It happened sort of gradually.

But Im not surprised.

Its such a wonderful thing to do with your life.

Itll never stop giving, in a way.

I believe in [acting] as art, and I believe in it as what we do.

Its a wonderful thing to do.
