Improvised Star Trek
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.

Talents emerge and a new crew member starts at the most important location on the ship: Starboards.


Rayna Caskey joins the cast as Ensign Bobbie Intern!


Also, you can see Chris, Sean, and Julia at the Cards Against Humanity Live! show at the Greenhouse Theater on Friday April 26th.

Responding to a distress call on a distant moon, the crew finds themselves treading water in the salty space ocean of their deepest fears. They'd probably all drown too but their cultural insensitivity to Rayvek and Tricorder 7Plus's keep them buoyed with self-importance. SHARK!!!

Will sparks fly when Rip and Rita crash land, or will the rest of the crew just stop responding to messages and totally ghost them for no apparent reason I mean why even bother swiping right if you won't even send a message to the person you swiped right on?
