Warner Bros.' Kevin Tsujihara talks AT&T, self-driving Batman cars and the DC universe

To say the entertainment industry has changed since Kevin Tsujihara became chief executive of film and TV studio Warner Bros. in 2013 would be an understatement. Netflix Inc. has become a disruptive force in film and television. Walt Disney Co. is about to become an even bigger giant when it absorbs much of 21st Century Fox and launches its own streaming service. Warner Bros. itself, at nearly a century old, is adjusting to new ownership under Dallas telecom behemoth AT&T Inc., which bought Time Warner Inc. (now called WarnerMedia) for $85.4 billion last year. The studio is coming off a strong year at the box office, grossing $5.6 billion globally with hits including "A Star Is Born" (which won the Oscar for best original song) and "Crazy Rich Asians."
