Check out what he had to say after the jump.

Collider: What sparked the idea for this film?

Around the same time, we were going through separate break-ups.

Over the course of a couple of months, it would start to take shape.

We would meet, every once in awhile.

It had those unambitious beginnings.

We just wanted to see what would happen.

Thats when we started thinking that we would take a stab at make it.

That then became the goal.

Do you work together, or separately?

LONG: We all work together.

Thats what took so long.

We would wait until we were all in the same place together.

Every couple of months, we would spend a few weeks together.

Weve been working on our own and mailing scenes back and forth, taking different parts.

Weve formulated different ways of working.

But with this, it was just when we were together.

It took us several years, and several different incarnations.

Because it was our first script, there was a certain learning curve that we needed to get over.

LONG: I prefer working under a deadline.

I fire off the risk of getting lazy and I can be complacent, so it just helps.

I like being creative.

Its just a matter of forcing the creativity, a little bit, with a ticking clock.

Someone is paying you, so its not fun and games.

LONG: Oh, god, yeah!

Another impetus for writing this was that it was a whole new world that was opening up to us.

It was uncharted territory, and I think it still kind of is to people.

it’s possible for you to misuse that, as a tool.

Its very easy to fall into that trap.

I think it can also be beneficial.

it’s possible for you to cut through a lot of the bullshit.

you’ve got the option to get to the heart of something.

you might be more efficient.

There are two ways of looking at it.

It can also speed up the process, for better or for worse.

LONG: Im so glad you said that.

That was the conflict of the movie.

There were a few versions of the script.

Wed get notes that say, You need a clear conflict.

you oughta introduce an ex-boyfriend, or a new potential love interest.

So, we settled on the conflict being within himself.

He gets in his own way.

Hes his own obstacle.

And thats something that I think is relatable.

To the three of us, it definitely was.

Sometimes thats the biggest hurdle, and I think thats something we hadnt seen too much of before.

Once hes in the relationship, he continues to get in his own way.

LONG: Yeah, for sure.

I always have a go at do that.

Ive just never had so much say, creatively, in the final product.

Keir and I did a fair amount of ad-libbing on sets.

We felt like that gave us some screenwriting experience, in a strange, round-about way.

It was always something Id wanted to do.

LONG: Yeah, absolutely.

Thank you for saying that.

I think that was a fear of mine.

Thats something that you dont really know until you see the way its all cut together.

Certainly, in script form, theres the danger of that.

So, it was scary.

At the end of the day, that comes down to how its directed and how its acted.

I just hope hes not too weird and unlikeable.

What are you going to be doing next?

LONG: Im doing both.

Were writing the pilot and have some deadlines on that, coming up before Kevins movie starts.

And then, Im going to go to Charlotte and shoot Kevins movie.

Its a very bizarre horror movie.

I dont even know what to call it.

I dont know what genre it exists in.

Its a strange movie, but I cant wait to do it.

I just saw my walrus suit.

Kevin sent me a photo of it.

Im going to be very claustrophobic for a couple of weeks.

Are you looking to star in the TV show?

LONG: Yes, thats the plan.

You just never know how these things will go.

They make so many of them.

But, thats what were hoping for.

Weve just started writing it, though.

Its a very recent thing, but exciting.
