Mahershala Ali met Viggo Mortensen in early 2017, at an industry brunch deep into awards season.

He and I just connected, Ali remembers.

It was special from the jump.

Emily Shur for EW

You gotta get it right.

I told him, Ill talk to you soon.

MORTENSEN:But what does that mean, Ill talk to you soon?

ALI:I had to talk with my wife, and people Im close to.

I knew I wanted to do it.

MORTENSEN:[Points to Farrelly] Buthedidnt know!

FARRELLY:Honestly, I knew if I got them, it would work.

I never doubted it for a second.

Given how toxic racism continues to be, were you ever worried that the movie wasnt serious enough?

Its been called feel-good.[Ed.

note: This interview was conducted before Mortensens use of a racial slur at a recent event.

He hassince apologized.]

FARRELLY:It has a positive, hopeful ending, but feel-good makes it sound squeakier-clean than it is.

[Laughs]

How did you decide when to add comedy?

Did the humor come naturally?

ALI:Things became funnier as we worked on them.

The truth is that this is a quirky situation, and it has levity to it.

FARRELLY:Yeah, I was keeping that in check.

I thought of trying to go for jokes.

Like farm dog

Sorry,whatdog?

Was that a deer or a… farm dog?

And we took out dramatic stuff, too.

The truth is, the tour went for over a year, up to when JFK got assassinated.

Don and Tony went to the funeral!

We had it in the script for weeks, and I just remember not liking it.

It would have been too heavy.

It was fascinating but ruined the flow.

ALI:It takes them out of the car.

MORTENSEN:And it would have been a two-and-a-half hour movie.

ALI:[To Farrelly] Youre gonna use it for the sequel, though, right?

FARRELLY:[Laughs] Yeah.

ALI:OrForest Green Book.

[Mortensen applauds]Lime Green Book.

Whats your biggest takeaway from working on this?

FARRELLY:The whole experience has been special.

When everything falls together like this, I feel unbelievably lucky.

And Pete was so open, the energy was super-positive…. And Viggo, what has stayed with you?

[They all laugh] Im kidding.

Green Bookis in theaters now.
