The restrictions on "Star Wars" spoilers have been well-documented since before "The Force Awakens" began shooting, with director J.J. Abrams threatening Darth Vader chokeholds upon anyone who dares violate the nondisclosure agreement that set visitors reportedly signed. We already know that translates to the cast, with Oscar Isaac telling The Huffington Post last year that they "can't say shit." Apparently it applies to the stars' parents, too.
For the best evidence of cast secrecy yet, just look to John Boyega's Twitter feed. Boyega, who plays a new character named Finn, posted a photo of himself washing dishes as punishment for refusing to tell his family any details about "The Force Awakens." (Don't sweat it, John -- spilling the beans could very well be a trap.)
We have about eight months of this confidentiality left, as "Star Wars: The Force Awakens" opens on Dec. 18, 2015.
