Once Arnold had filled in a cast slot, he was there to stay. His writing contributions (usually compiled with his wife Stephanie) have become a significant part of the show's creative process, and his rapid wit during the final line attribution sessions are a constant source of inspiration for the performances. Arnold is curator of Geppi's Entertainment Museum in Baltimore.

Dave has been part of the Mysterious Theatre 337 team since its inception. For most of the early (pre-2003) shows, he was in the cast; in later years he has been unable to attend shows but still contributes regularly as a writer. Dave has always been valuable to us as he is more a Mystery Science Theater 3000 fan than a Doctor Who fan, which has helped keep a MST3000 feel to our shows. Dave works in the IT field in the higher education industry.

Peter joined the group in 2003 as a last-minute cast replacement, and he subsequently performed in the 2004 and 2005 Chicago shows as well. Since then he has been unable to join us for another show, but continues to write and handle other tasks for the group. I'm ashamed to admit I don't know what Peter does for a living.

Steve created Mysterious Theatre 337 in 1996 as a replacement event for the dwindling Visions convention dance, and it has clearly been a success. Even now after over two decades, he still learns of new and better ways of doing things to make the show happen. In mundane life, Steve is in telecommunications infrastructure design and has too many hobbies that involve buying things. He is the author of three books including Red White and Who: The Story of Doctor Who in America and Silver Scream: 80 Classic Horror Movies, is co-owner of the Gallifrey Base forum, and is the programming director for the Chicago TARDIS convention.

Rick has been a key figure in the development of Mysterious Theatre 337, most significantly being the head writer for a number of years. Though his contributions have lessened in the recent past, he still occasionally works on new shows when time permits. Rick is in the IT field in the higher education industry.

Even though Dennis has never performed in a show, and doesn't often contribute much material to the scripts, he has attended many writing sessions and is our "official photographer" which is why he's seen taking a few flash photos of our shows even when the con programs say flash photography is prohibited. He also consistently provides essential backstage help. As far as I know, Dennis is a cellular communications engineer.

John's been an "official" part of the Mysterious Theatre 337 group since 2004, though he's certainly been helping us longer than that, and lately has been a valuable part of the writing team. He and Dennis are usually the two main men backstage during the shows, our top crewmembers. John is a Master of Library Science and therefore loves to organize things.

Shaun wanted to join the cast for our Silver Nemesis show but had to bow out at the last minute due to time constraints. He managed to make the very next show, though, and proved to be a natural at it. And we think he's enjoying it. Shaun is the author of Back to the Vortex and Second Flight, and for many years was the owner of the Outpost Gallifrey forum. He is the programming director for the Gallifrey One convention.

Rob has been part of the Mysterious Theatre 337 team since its inception. Up until episode 200701, he was the only person other than Steve to have performed in every show. As we have observed in our question and answer sessions, Rob usually gets the "rude" lines in the scripts. Rob is an accomplished and talented musician in his spare time.

Scott joined the Mysterious Theatre 337 team in 2002 and quickly became one of the driving forces behind the show. Scott is a writer/producer in the television industry, and has written a number of works for Big Finish, such as the final chapter of I, Davros.
