A Quiet Place marks the first time Hollywood couple Emily Blunt and John Krasinski have worked together.

He also directed the thought-provoking horror film, set in a post-apocalyptic world where terrifying creatures attack anyone who makes noise.

Silence is the key to survival – a complicating factor for parents trying to raise children.

Blunt and Krasinski talked to entertainment reporter Kim Holcomb about how their own fears translated into terrifying moments on-screen.

KRASINSKI: "Three weeks after we had our second daughter, I got this script, and I was wide open. And as you know, I was feeling terror and fear and, 'Can I keep this girl safe, can I keep her alive, am I a good enough person to be her dad?' All these big questions. Which is exactly what this movie deals with."

HOLCOMB: "I feel like I would not have survived a day because I tend to be pretty clumsy.”

BLUNT: “Yeah, you would die.”

HOLCOMB: “I would die - you can tell just by looking at me.”

BLUNT: “I can tell. (laughter)”

HOLCOMB: "What is weirder, directing Emily or directing yourself?”

KRASINSKI: “It's interesting, I think directing Emily was weirder because I think in the beginning, I was genuinely nervous. She's truly my favorite actress… I know it sounds corny, but I'll never have a better collaboration than I did with my wife. She was so unbelievable to work with."

HOLCOMB: "(The movie) plays on insecurities. When your baby is crying and you're trying to calm the baby and you can’t figure out how to calm the baby - this is like ten times that.”

BLUNT: “This is the magnified version of any stress levels parents feel. I think that was important to John that, yes, it's terrifying and you've got some massive jump scares and it's horrible, it really puts you through the ringer. But it's ultimately about parenthood."

HOLCOMB: "It's definitely also not a popcorn-eating film because I found myself starting to, and I was like... (freezes)”

KRASINSKI: “That's exactly right. One of my favorite stories is, we tested the movie 5 or 6 weeks ago. This one guy raised his hand, shaking, and was like, 'I need you to know that I snuck a bag of Skittles in this movie and the whole 90 minutes, I was like this.' (freezes) And he couldn't open his bag. And I'm like, 'That's the best compliment about this movie, ever!’ It's an experience, which is really fun.”

HOLCOMB: "What did you learn about yourself and your own sort of vocal footprint?”

BLUNT: “The way you can move around in real life is effortless. It's painful to live silently. It's hard."

HOLCOMB: "Do you have a nice quiet place?”

BLUNT: “During nap time. That's the best. Just go meditate on my bed and pass out, snoring. I don't actually meditate. I just end up sleeping."

A Quiet Place is rated PG-13 and opens April 6.
