Adam Driver hasn't been told to keep quiet about the secrets of 'Star Wars'.
The 33-year-old actor reprises his 'The Force Awakens' character Kylo Ren in the upcoming 'The Last Jedi', and though plot details have been kept firmly under wraps by the cast and crew, he revealed there is no formal obligation for them to do that.
He told GQ magazine: "There's probably something in my contract. I don't know - but it's kind of unbelievable that no one has told me, 'Don't say anything'. It's just implicitly understood."
But Adam is careful not to divulge anything about the story if he can help it.
Asked if he enjoys working with Daisy Ridley, who plays Rey, he said: "That's hard to answer. I mean, people assume we'd spend time with each other. Maybe our characters see each other in the movie."
And asked if he had scenes with the late Carrie Fisher, he added: "It's hard to answer without being vague."
However, one thing the star could confirm was whether fans will get to see Kylo Ren without his iconic mask.
He said: "I can answer that. You'll see it off in the new trailer so I'm not giving anything away."
Adam particularly enjoyed working 'The Last Jedi' as he didn't feel as much pressure as he did when he first joined the iconic sci fi franchise.
He said:" The first one was all, 'You can't f**k it up you know? There was a lot more hanging out this time.
"Then there are just practical things, like I have a lightsaber. That's fun."
The star revealed he and producers on the film agreed studying radical extremism was a good starting point for his character.
He said: "We talked about terrorism a lot. You have young and deeply committed people with one-sided education who think in absolutes.
"That is more dangerous than being evil. Kylo thinks what he is doing is entirely right and that, in my mind, is the scariest part."
