Improvised Star Trek (extras)
Improvised Star Trek explores 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. To learn more about the show check out our website, facebook page, or twitter!
Improvised Star Trek is fan production. Star Trek is property of CBS/Paramount.

Inadvertent cruelty is rampant in this bonus scene.

News of the week: there are three more live shows left for 2015! Join us December 4th, 11th, and 18th at 10:30pm.

Improvised Star Trek won the 2015 Audioverse award for best Fan/Adaptation Comedy! Many thanks to all who voted for us.

News of the week:
Thanks to all our world-wide iTunes reviewers, whom we recently discovered!

Help us upgrade our mics!
We're looking for donations to help us get brand new, much improved microphones for the show. This will improve sound quality, but also help us avoid some of the technical difficulties we've had over the last couple years that have sometimes led to lost episodes.
If you donate $25, we'll send you five (5) unreleased episodes! These are episodes we improvised but never produced as full episodes, so they are without sound effects but still very funny!
Hello from the Magic Tavern!
IST's Irene Marquette is on this week's episode of Hello from the Magic Tavern, a hilarious improvised fantasy podcast also featuring our own Matt Young. For a good time, download this podcast.
