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!
