Carrie Fisher, Gary the dog, Daisy Ridley and John Boyega appeared on The Graham Norton Show to talk Star Wars: The Force Awakens, and it turns out that some of them had a lot of trouble keeping their involvement in the film a secret.
Ridley managed to keep it on the down low. Boyega said that after he was cast he immediately told his taxi driver, who was unimpressed.
But Fisher spilled the beans to Norton, who was then burdened with secrets about the film for a year.
