Billionaire investor—and guitarist for Ghost Hounds—Thomas Tull talks to Guitar Center CEO Gabe Dalporto about entrepreneurship, creative leadership, making blockbuster films and being a gamer and comic-book fanboy. (The Guitar Hero video game was one of the inspirations for making It Might Get Loud with Jimmy Page, The Edge and Jack White.) As founder of Legendary Entertainment, Tull started out making films he wanted to see, while simultaneously developing ways to use data analytics to improve the marketing of the company’s films.
