The two actors star in Robert Eggers' new horror-drama The Lighthouse.

So that meant we did have to build it.

And did it actually work as a lighthouse?

The lobster fishermen of Nova Scotia could see it from very far away.

There was a real lighthouse farther up the peninsula, which couldnt hold a candle to our lighthouse.

I cant imagine they liked that very much.

But the community was incredibly supportive of the film.

Pattinson reveals that Eggers even had him wearing period-appropriate undies.

Hes completely meticulous, the actor says of his director.

We were wearing period-correct underwear, which you never saw, ever.

Everything was incredibly particular.

Dafoes appearance was augmented by gnarled false teeth.

I joke my teeth arent great, but they arentthatbad, he says.

It becomes a mask, it becomes a trigger, it makes you feel different.

It helps you enter into another character.

So that was important.

But who would make the best real-life lighthouse keeper out of the films two stars?

Dafoe, for one, has no doubt about the answer: He would.

Didnt youtalkto Rob Pattinson?

the four-time Academy Award nominee says with a laugh.

Do you want that light to stayon?

As it happens, Pattinson is in agreement on that score.

Im kind of a mess, no matter what I do, he says.

I think Willems much more interested in ritual and stuff, and Im much more lazy.

I dont think either of them should be lighthouse keepers, he says.

I think that they should stick with their current careers.

The Lighthouseis currently playing in select theaters and will expand nationwide Friday.
