Star Trek: Short Treks is an American anthology web television series created for CBS All Access by Bryan Fuller and Alex Kurtzman. It is a spin-off from the series Star Trek: Discovery, and consists of several shorts that utilize settings and characters from that series and the wider Star Trek universe. The shorts are between 15 and 18 minutes in length. After signing a deal to expand the Star Trek franchise on television, Kurtzman announced Short Treks as the first such project in July 2018. The first four episodes aired from October 4, 2018 to January 3, 2019, between the first and second seasons of Discovery. The shorts were mostly produced by cast and crew members from Discovery, including composer Jeff Russo who provided a new main title theme for the series. Filming took place on the Toronto, Canada set of Discovery.
