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.
