Her new rom-com, the idea of you is inspired by, get this, Harry Stiles fan fiction.

You've got Anne playing a 40-year-old who starts a relationship with a 24-year-old boy band member who's a singer.

The trailer is the most-watched trailer ever for a streaming movie, and Anne is excited about it.

I loved making this movie more than I can possibly express.

On stage for the premiere at South by Southwest, Anne teared up at the crowd's ecstatic reaction to the film.

It's nerve-wracking, you know, because I know how I feel about it.

I love it, and you want to be able to share that with people.

Did I not warn you?

People hate happy women.

At 41, Anne says she keeps blooming.

That theme is at the heart of the idea of you.

I don't know if you remember me, but we met in Coachella.

Yes, I remember you.

I think that finding someone that you connect with is so rare.

It's so unusual, and it's so crazy to find someone that you can grow with.

And I like to imagine a world in which when somebody finds it, like, we're all just really happy for them.

And that's all.

Playing her love interest is 29-year-old British actor Nicholas Galatine, who had no nerves going into the romantic scenes with Anne, or Annie, as he calls her.

I'm too old for you.

Hang on.

I so respect and just love who Annie is as a person, and I think we both love our characters, and we love each other's characters.

I think that made all of that work just really enjoyable, even when it was heavy in certain scenes, which is really exciting as an actor.

Hold on, kid.

Is this the one you were talking about?

Couldn't put it down, fellas.

The idea of you streams on Prime May 2nd.

Very realistic.

Very realistic.

In my heart. . . .
