Secrecy is the name of the game when you’re filming a blockbuster these days, especially one tied to a franchise as huge as Star Wars. And the lengths to which studios will go to keep things under wraps means that actors themselves often don’t even know all of the details, like, say the official title of the films they’re working on.

The next episode of Star Wars is done filming, and Daisy Ridley, who plays Rey, appeared on the My Dad Wrote a Porno podcast to talk everything from Wookiees to wampas. But she wasn’t able to answer every question. When asked what the title of the new film will be, she said, “I heard a title, but I don’t know if it’s going to be that. I heard the title a long time ago before we started filming, and so I feel some things have slightly tweaked during production. It’s going to be a while before it’s released, I imagine.”

This isn’t as odd as it may sound. The title for The Force Awakens was revealed a little more than a year before its premiere, but it filmed under a completely different name. Lucasfilm’s Creative and Story Executive Pablo Hidalgo said on Twitter that Episode VII had been called “Shadow of the Empire” during production. And the original trilogy’s third film, Return of the Jedi, famously filmed under the title Blue Harvest to throw off potential set spies.

With 15 months to go before Episode VIII hits theaters, now’s a good time to start speculating about what the title could be. Some thoughts: * Star Wars Episode VIII: Revenge of the Nerf-Herders.
