Exoplanetary

EXOPLANETARY is a science-fiction adventure that follows four siblings, the Wolverton family, as they work for a giant corporation named Exoplanetary. Their bosses want to expand their business beyond our solar system, but the Wolvertons just want to enjoy their lives. Where do the morals and happiness of ordinary people fit in a universe full of rich and powerful interests? The stories are exciting, funny, tragic, and always slightly offbeat. A science-fiction audio drama featuring serialized space opera, adventure, and a healthy sense of humor. © 2014-2025, C. Christopher Hart, All Rights Reserved.

Due to circumstances beyond our control, Exoplanetary’s live show at OMSI that was scheduled for this week has been postponed. 

The good news is that the show will go on. Thursday, September 17, 2026 is the new show date. If you already bought tickets for the old date, they will work for the new date. 

And, if you haven’t bought tickets yet, now’s the time. There will be a link in the show notes (see above). We rehearsed it the other day and we have a funny, exciting adventure to share with you. It’s all-new and is a great jumping-on point, so if you want to bring your friends, you won’t have to explain anything to them, other than that they will have a great time.

It’s a show, in space, about technology. And this episode will be called “Attack of the BattlePyramid.” Because if you come across a BattlePyramid, odds are something’s getting attacked.

I’ll share more once there’s more to share but for now, I look forward to seeing you there. 7pm, Thursday, September 17, 2026, at the Empirical Theater in the Oregon Museum of Science and Industry, in sunny Portland, Oregon

Oct 24, 2024

My friend, Sam Mowry, died on July 20. If you’ll indulge me for a few minutes, I’d like to talk to you a bit about Sam, who he was, how he came into my life, and how he changed it.

Of course, everyone you know changes your life. When you open your heart and connect with someone, you change; sometimes in little ways, sometimes in enormous ways. I feel this about the people involved in EXOPLANETARY. But Sam Mowry had a way of involving himself in people’s lives, and really showing you that he loved you. All of my memories of Sam are happy ones, and every story I have about him involves his indefatigable kindness. To me and everyone else.

It was just as we were finishing up the first season of EXO that I met Sam. I was summoned! There’s really no other way to say it. A few actors and radio theater people were asked to come to the place I am now: Sam’s studio. You’ve seen it in many of our pictures on social media, with those theatrical red curtains and Sam’s old radios. Sometimes you walk into a room and you feel right at home, and that was the case here. We read through a few scenes of an adaptation of The Island of Dr. Moreau and I made some aggressive snarling noises as a Beast Man. Afterwards, Sam and I got to talking about radio theater, old movies, and it was that sort of bonding you do with someone who becomes one of your best friends. Maybe you don’t know it when you start talking, but you know it when the conversation was over.

I was summoned again not long afterward on a sunny afternoon for a visit under Sam’s famous Casbah, a sort of covered patio where many a salon for theater people and other friends had been held. It was there that Sam encouraged me to start recording EXO in his studio. 

You could have knocked me over with a feather. The studio provided my show with something it hadn’t truly had before: a home. Sam and his wife, Cindy McGean, took me and my actors in so warmly, and it’s the greatest gift I can ever imagine.

It was one I was eager to return. For the remainder of our time together, I helped him with every production of his company, the Willamette Radio Workshop. I even got to perform with him a few times.

Sam was a friend, but he was also a mentor. I have always been a reluctant leader; I just don’t see myself in that role. As I grew up, I also had some examples of leadership that didn’t exactly leave me eager to be in charge. Unfortunately, to do what I’ve needed to do to make EXO happen, I needed to find that part of me and get it in gear, to varying degrees of success. What Sam taught me was how to be a positive presence in people’s lives, how to deal with obstacles, how to foster a sense of fun and community, and, really, how to be the best version of myself.

We shared deeply about our hopes and dreams for creating shows and spaces for performing. It wasn’t unusual for him to bring up some empty restaurant space or office building or some other edifice and muse that it would be the perfect place to start a theater. As one of Portland’s foremost and most beloved theater people, Sam was constantly looking for new ways to put on a show, even as poor heath made it more and more difficult.

Sam loved everything to do with radio. Something we both had in common was sleepless nights when we were young, searching the AM bands for what they now call “OTR.” Old Time Radio. Fibber McGee and Molly. Vic and Sade. The Jack Benny Program. And, of course, Orson Welles. Because of Sam’s voice, he drew a lot of comparisons to the Great Man. When Willamette Radio Workshop performed the War of the Worlds, he took Orson’s parts. Who else could? But Sam also did an impressive Sydney Greenstreet, which was wickedly funny.

Sam really loved the magical feeling of a device pulling voices out of the air, picking them up from faraway cities. He was, at heart, a romantic. 

Having Sam in my life meant that I was constantly coming up with characters that I wanted him to play. You’ve heard him as Long John Silver and a space cowboy named Jonas. I had so many more things I wanted him to play, but we didn’t have the time. 

Sam is also in the plays I was finalizing at the time he passed. Knowing that these are probably his last performances in radio theater... well, that has been a big responsibility. Those of you who are Patreon supporters have already heard one of them, and the other is coming shortly. If you aren’t a supporter, you’ll hear these on the main feed in the coming months.

Sam Mowry was one of the best friends I’ll ever have. He taught me so much, gave me so much. We would meet people, total strangers, and he would introduce me as Christopher Hart, the creator of the science-fiction audio drama podcast EXOPLANETARY. As if they might have already heard of me, and that were the greatest thing in the world. There’s another gift: teaching my tired, cynical heart to think that, yes-- maybe it was the greatest thing in the world, after all?

This is what your friends do for you. The best friends teach you how to see yourself. They teach you their way of seeing you. Encountering so many of Sam’s friends, one really amazing thing about this guy was, he did some version of this for nearly everyone. And now that he is gone, we each have the task of doing this for other people, and teaching them to do the same. 

It’s a legacy of love, and I hope that in telling you a bit about my friend Sam Mowry, who took a bow on July 20, 2024, I am doing something to pass it on.

This includes scenes from the EXOPLANETARY episodes "The Pirates of the Cormorant Nebula," "The Purple Fields of Violon," and "The Purple Reign."

If you would like to offer a tribute in Sam's name, please consider a donation to the Oregon Food Bank, which was one of his favorite charities.
