Improvised Star Trek
For ten years Improvised Star Trek explored the final frontier of comedy by turning Star Trek into an improv office comedy. Taking suggestions submitted on Twitter and Facebook, the cast (featuring some of Chicago’s top improvisors) creates a fully improvised episode detailing the adventures of the USS Sisyphus, a less enterprising starship. New episodes are posted every other week. Improvised Star Trek is a fan production. Star Trek is property of CBS.

When a starfleet officer is held prisoner on planet Florgorn, a crack team from the Sisyphus is sent to free them.

Announcing several changes to Improvised Star Trek!


Firstly, new episodes will now be released biweekly instead of weekly. While we're sorry to make you wait longer between adventures of the USS Sisyphus, the new schedule will ensure that episodes arrive reliably on time, and that every episode meets our highest production standards.  It'll also free us up to produce bonus materials we've wanted to provide. Expect to hear some extras coming your way soon, hopefully to tide you over between new episodes.


Secondly, we're thrilled to welcome a new member to the cast, Mary Cait Walthall.  Mary Cait is an active member of the Chicago improv community, and we're all thrilled to have her on board the Sisyphus.   Listen for her in upcoming episodes!


Lastly, thanks to all of you who listen. If you're a fan of the show, keep spreading the word to your friends. Thats all for now, but we've got some exciting stuff in works, so keep listening, and watch here for all your Improvised Star Trek news.

Note from IST: Earlier versions of this episode included some defamatory language. It came up in the live improvisation as an example of bullying, and at the time we produced the episode we hoped listeners of the original cut wouldn't mistake its usage as any endorsement.
Nevertheless, we ultimately decided that its inclusion didn't say or add anything thoughtful enough to outweigh the possible pain it might cause listeners who've been attacked with such language. So we've cut it out. As Trek fans we strongly believe in a future (and present) where are all treated with dignity and respect, and as comedians we endeavor for our work to be as smart and humane as it is clever.

Welcome to Improvised Star Trek!  Our first "season" starting in April 2011 was a ton of fun, but there was a bit of learning curve taking our live stage show from iO Chicago and turning it into a podcast.  Early episodes suffer from audio problems (though we're humbly submit that we took less time than TNG to find our footing), so for that reason we've pruned the first season a bit so that only episodes recognizable as what Improvised Star Trek became are available in the feed.

Still, we understand Star Trek fans are completists by nature, so if you see any episode numbers missing and need to know what we cut, you can still hear them by heading to our website:
