The musical episode of "Star Trek: Strange New Worlds" landed yesterday. Showrunners Akiva Goldsman and Henry Alonso Myers talked to IndieWire about how it got made, and the challenges of working with a cast of varied vocal skill, from the polish of Rebecca Romijn (First Officer Una Chin-Riley) to Anson Mount (Capt. Pike), whose most notable on-screen singing was in a car with Britney Spears in 2002’s “Crossroads."
