Which also serves as a disadvantage, according to the team. Hollywood bigwigs interested in financing the film would likely want to dumb it down with a different ending or a gorgeous cast.

“Did we say ‘fat’? We meant ‘hot’,” Munro says with a smirk.

The couple thinks being based in the Bay Area is another advantage.

“There’s such a literary boom here, so much material,” Castleton says. “Even as small as we are, a lot of people come to us with books or stories that might be movies. I’d love to be in a position to help jump start projects, and executive producing is a perfect way to do that, but it means having some money behind you.

“My fantasy is that we’d have a discretionary fund for development of projects,” she muses. “Once in a while something will get my attention, and I’ll think, God, if I just had $10,000 or $5,000, I know exactly who I would call. [I’d] get a crew to go and see if there’s a story there and then go cut something together and find the financing.”

“The business part of that is to determine what your outlay of money is going to buy that is going to [help you] get the rest,” Munro adds, “putting together a trailer or a teaser or hiring somebody to write a pitch.”

“Yeah, all of these pressures at once, and being involved in all of these things intimately, as a couple, is a lot,” Castleton says. “Sometimes it’s like, ‘Ooh, I’m going to the grocery store by myself!’ ”

“We can’t continue in these roles - we’ve had to assume all of them for this film, but whether we were married or not, it’s just too much,” Munro admits. “So after this, we’re going to look at taking on a partner to handle the business side of things and free us up to do the things that really feed us. But it’s like climbing Everest with somebody; the most trying experiences are the ones that I think we’re really proud that we’ve shared and gotten through.”

“But I’m dying to be able to do more creative work,” Castleton says wearily. “We wrote this script a long time ago and I’ve pretty much been a producer since then, and the constantly selling - it’s exhausting.”

“The hustle, it takes it out of you,” agrees Munro.

“Yeah, it just hit me, we’ve been doing that for three years now,” Castleton continues. “We just talked about it the other day, what comes after [Full Grown Men]. There’s going to be, if there’s any way we can afford it, some time to recuperate. We want to be real people, eventually.”

Her husband laughs. “That’s really well put.”

Grottofilms began shooting Full Grown Men in Miami on July 18.

It’s obvious Munro and Castleton work well together, but marriage is enough of a challenge without the added stress of getting a production company, and its first feature, off the ground. How do they handle it?

“If we didn’t work together, we’d never see each other,” Munro says. “I can’t imagine trying to have a relationship, it would just be retarded. But we [have to] take vacations from each other in little ways, nights off,” he says, smiling at his wife.
