Actor Matt Ross talks with Recode’s Kara Swisher about playing Hooli CEO Gavin Belson on HBO’s “Silicon Valley,” which just started its fourth season. Ross, who previously played Alby Grant on “Big Love,” says he tries to make the antagonists he plays sympathetic and sincere, even in a goofy comedy like “Silicon Valley.” He also talks about his first film, “Captain Fantastic,” which was nominated for an Academy Award and a Golden Globe, and the balance between tech companies and Hollywood, as Amazon and Netflix bid for top film and TV talent. That competition has been great for outsiders getting their stories told, but Ross wonders: What happens if the new money goes away?
