Mark Millar is ushering in Netflix's new superhero universe with 'Jupiter's Legacy' By The Washington Post By David Betancourt The moment that Netflix arrived in Mark Millar's life came decades before he thought it would. Three decades, most likely. "I thought I'd have a few more gray hairs before this happened," Millar, 51, told The Washington Post. Millar is no stranger to Hollywood. Through his stellar run as a writer at both Marvel and DC Comics in the early 2000s, he became one of the biggest names in the industry. His stories sparked much of the modern comic book movie boom, including "The Ultimates" series, which he wrote for Marvel with artist Bryan Hitch and is widely considered to be the inspiration for the first "Avengers" movie.
