James Cameron’s Titanic is a cottage industry unto itself. Nearly 20 years after its release, the Oscar-winning film that launched Kate Winslet and Leonardo DiCaprio to global stardom—and propelled Cameron to Hollywood box-office domination—has inspired a small fleet of post-Titanic content. Much of it has been championed by the director himself: he’s participated in several specials about the film and the real disaster that inspired it, including a 2012 National Geographic special titled Titanic: The Final Word with James Cameron.

Apparently, we’re operating with different definitions of “final”—because on Tuesday, word broke that Cameron is making yet another Titanic special with NatGeo, this time to celebrate the film’s big anniversary. (Meanwhile, Cameron has continuously pushed back the release of his long-delayed Avatar sequel, which is currently slated for 2020—a mere 11 years after the first film’s release.)

Simply titled Titanic: 20th Anniversary, the one-hour documentary will examine the film’s accuracy, per Entertainment Weekly.

“When I wrote the film, and when I set out to direct it, I wanted every detail to be as accurate as I could make it, and every harrowing moment of the ship’s final hours accounted for,” said Cameron in a statement. “I was creating a living history; I had to get it right out of respect for the many who died and for their legacy. But did I really get it right? Now, with National Geographic and with the latest research, science and technology, I’m going to reassess.”

This is, of course, freakishly well-trod territory, as the film’s accuracy has been explored to death in the decades since its release. Cameron’s obsession with getting all the details right has also been carefully documented—he was famously manic about everything from the decor in the ship’s posh dining rooms to Rose’s Heart of the Ocean diamond, which he designed himself. He even digitally altered the night sky in one scene for a 3-D re-release of the film so it could be anatomically correct, after being pressed about it for years by astrophysicist Neil deGrasse Tyson, a man who has never, ever let sleeping dogs lie.

The new NatGeo special, set for a December release, will employ “new technology to analyze the critical choices made during the production, go inside Cameron’s personal journey while making the film, and follow the director and a team of experts to a Titanic exhibit at the Ronald Reagan Presidential Library,” E.W. reports. It is unclear, however, if Cameron will finally admit once and for all that there was room for both Rose and Jack on that floating piece of wood. There was room on that door for both of them! MythBusters said so! Stop forcefully denying and admit it, Cameron: the truth shall set you free!
