It would seem a basic level of Star Wars trivia is not a prerequisite to being cast in a Star Wars movie.
At least it wasn't the case for Carrie Fisher, Adam Driver, Daisey Ridley and John Boyega as they were schooled by 7 year old Arden Hayes on Jimmy Kimmel Live.
It was messy. The cast didn't even score a single point. Arden was more ruthless that Anakin Skywalker when he done away with the Jedi younglings.
The force is strong in this one.
