The most recently revealed addition to the cast is comedian Tig Notaro. The actress and writer has signed on for a guest role, Variety reports. She'll appear as a new character named Denise Reno, the chief engineer of the U.S.S. Hiawatha.

Notaro comes to the series having hosted podcasts, done stand-up, and written several projects. Not only did she star in Amazon's "One Mississippi," she co-created the series with Diablo Cody. Some of her other recent work includes the upcoming film "Dog Days," a multi-episode arc on "Transparent," and the Netflix documentary "Tig."

The actress's casting comes in the wake of another addition -- that of Anson Mount. Unlike Notaro, he'll play a character fans of the franchise have already seen -- Christopher Pike, captain of the U.S.S. Enterprise. Pike has been played by multiple actors since the original series, including Jeffrey Hunter, Sean Kenney, and Bruce Greenwood. Pike placed a distress call at the end of "Star Trek: Discovery" Season 1, and it was received by the U.S.S. Discovery, bringing the Enterprise into the story.

Season 2 will pick up with more of the Discovery's adventures. Its premiere date has not yet been announced.
