Halston Sage (Crisis) and Penny Johnson Jerald (Castle) have landed series-regular roles in Fox’s untitled live-action hourlong comedic drama created by and starring Seth MacFarlane. Jon Favreau is set to direct the first episode of the series, which is set in space 300 years in the future and follows the adventures of the Orville, a not-so-top-of-the-line exploratory ship in Earth’s interstellar fleet.

Character details for Sage and Johnson Jerald’s roles were not provided, as has been the case with other castmembers including Adrianne Palicki, Scott Grimes, Peter Macon and J Lee. Sage co-starred on the NBC series Crisis, and her recent film credits include Goosebumps, Paper Towns and Scouts Guide to the Zombie Apocalypse. Repped by CAA and manager Jason Weinberg, she next appears in the features You Get Me and Before I Fall.  Johnson Jerald was a regular on Castle for four seasons, played Sherry Palmer on 24 and was the titular character’s personal assistant Beverly on The Larry Sanders Show, among many other TV credits. She is repped by Mitchell K. Stubbs & Associates.
