Shipbuilding

“Star Trek: Discovery” didn’t exactly rock the universe when it premiered, but the show’s creators are hoping to lure skeptical fans on board for the second season with more nods to the franchise’s roots. Anson Mount joins the cast as Christopher Pike, the USS Enterprise captain in the original, scrapped pilot episode who was quickly replaced by James T. Kirk. Jonathan Frakes, who played Commander Riker in “The Next Generation,” directed next week’s episode.
