"So how does one go about selecting their prosthetic penis? Is it like Build-a-Bear or something?"

That's the type of question "The Overnight," in select theaters June 19, invites one to ask.

The very funny (and surprisingly emotional) Sundance hit -- which stars Parks & Rec") and is produced by his wife, Naomi -- centers on Scott's character, Alex, who recently moved from Seattle to Los Angeles with his wife, played by "Orange is the New Black's" Taylor Schilling. The couple accepts a dinner invite from neighbor Kurt, the self-described "mayor" of the neighborhood, played by Jason Schwartzman. Soon, their nice evening escalates to include "swinging," a kinky pool-side chat and full frontal male nudity.

But "The Overnight," from writer-director Patrick Brice, is more than just clever dick jokes. It also has a refreshing amount of heart and unflinching honesty as it explores the risk that relationships run of growing cold and how to preserve one's spark before that happens.

In addition to premiering the poster for the film (below), Moviefone recently talked with Scott about making the film -- the first feature from the Scott's Gettin' Rad Productions -- as well as juggling the film's tonal shifts, its very relatable themes and, of course, the aforementioned stunt junk.Moviefone: As great as the humor is in "The Overnight," its thematic aims -- about relationships and the pressures to re-invent ourselves within them -- are just as important. How did you and your wife go about developing the film's story?

Adam Scott: It all started with the script that Patrick wrote. I've been a dad for eight years now, so a lot of the themes -- they really resonated with me. Because, at a certain point -- for good reasons -- you realize who you are, and where you fit in the world. You realize you're not in your 20s or early 30s anymore, when you were sort of navigating the world to find your place in it. But I do believe it's healthy to do once in a while, and these characters are kind of yearning for that [kind of reinvention] and sometimes they don't even realize it.

Right. And I like how the audience -- we're never ahead of the characters on that learning curve.

Exactly. That's something we set out to do.

Now Mark Duplass brought the script to your company. What was that process like?

Well, the script was ready to go. Mark brought it to Naomi and I, and usually when you read a script -- there's like a ten or twenty percent chance it'll get made. But we really wanted to make it, and get our company's first feature under our belt... I'm really happy that we did it, because I love the movie – and it resonated even more with me as we were making it.

It got a great reaction at Sundance earlier this year. How gratifying was that to see it resonate with audiences as well?

Well, the really gratifying reaction is seeing how much of crowd pleaser it's turned out to be.

Were you expecting that?

No. No, we really didn't know that going in -- and we certainly didn't know it until we showed it to that first audience at Sundance and they had that wonderful reaction. You know, we had that wonderful problem of wanting the audience to "shut up" more than anything [laughs] because, they would be laughing at one joke and there would be laughs covering the next joke that you wanted everyone to hear. But that's just a problem you crave for because you never think it's one you're gonna have. We're hoping that once it hits the public, they'll enjoy it just as much.

One of the scenes that gets a big reaction is your bit of full frontal nudity. It's really unexpected.

Yeah. Yeah, the reactions have been interesting there.

So just how does one go about selecting their prosthetic penis? Is there a catalog? Is it like "Build-a-Bear" or something?

Yeah, it's actually at a store at the Glendale Galleria.

Nice. Do they validate, or...

[Laughs] Yeah, for sure. It's great service. Actually, the four of us -- me, Naomi, Patrick and [producer] Mark Duplass -- we kind of went through, over email, the whole process of choosing just the right penises. At first, it was kind of "giggle-filled" but once we really got down to it, we adopted this very business, workman like attitude toward it. Talking about girth and length –

-- Things like "D2F" ratio --

Right, yeah. But sort of in the coldest, most scientific manner you could.

Other than that, what was the working relationship like making this film with your wife? Did you guys have any challenges keeping a work-life balance?

We kind of agreed that, obviously there are some sensitive scenes in the movie so me and Naomi agreed that -- on days when me and Taylor may share an intimate scene in the movie, Naomi would maybe stay away from set on those days. But while we were shooting, we were having such a good time and getting along so well, it never really came up. It really wasn't that big of a deal, so it was never awkward. It was just fun.

Are they any deleted scenes fans can expect on the Blu-ray?

There wasn't a lot left on the floor. We shot it really quickly -- we shot the whole script, but I think there may be some extended scenes. And some bloopers -- we're working on some stuff -- but in terms of big, missing scenes, there really aren't any.

Was there a particular scene for you, while shooting, when you thought "Wow, we may have a good movie here?"

There's a scene where Taylor and I are out on the patio, after my character has this "spiritual breakthrough" of sorts -- we have this conversation, and it was so great working with Taylor... and I really felt like it was one of those moments you get once in a while when you're working with someone so talented you just forget that you're acting. It doesn't happen all the time.

And it's not a huge scene, but a very important moment in the movie. And I just sort of thought this could be something special.
