Writer-director-actor-singer Seth MacFarlane loves the orchestra — not just as backing for his albums and live musical appearances, but for his movies and TV shows too. He is a fan of classic movie scores and understands the value of real musicians helping to support the emotional needs of both drama and comedy. So for his new sci-fi series The Orville, debuting Sunday on Fox, he enlisted the services of three of the finest orchestral composers in Hollywood: Bruce Broughton, who scored the pilot and wrote the theme; Joel McNeely and John Debney, who are scoring the individual episodes. They are using orchestras of 60 to 70, which is much larger than the average TV ensemble these days. In this story for Variety, MacFarlane, Broughton and McNeely talk about the challenge and the fun involved.
