It’s been 13 long years since Avatar—or any other film directed by James Cameron—debuted on the big screen. Hollywood has transformed since then: In 2009, Blockbuster hadn’t even declared bankruptcy yet. Since then, Disney has acquired 20th Century Fox, the studio that financed the first Avatar movie; expensive action films without superheroes now rarely get the green light, unless they star Tom Cruise; and streaming has crippled the movie theater business. Yet Avatar remains the highest-grossing movie in history.
