Source: [VanityFairHollywood] Lots of cameos I seem to have missed after watching the movie twice! Most interesting one is Craig Daniel IMDb [Liar, liar, pants on fire!]. He plays the stormtrooper who gets himself Jedi-mind-tricked by Rey in the questioning room! [“And, I’m dropping my weapon…”]
Also interesting: Jessica Henwick IMDb [one of the Sand sisters from Game of Thrones] and Thomas Brodie-Sangster [Newt from Maze Runner]. Jessica plays Jess Testor, Poe Dameron’s wing”man”.
Thomas Brodie-Sangster IMDb [Game of Thrones, Maze Runner ], First Order Petty Officer Thanisson [the guy on the bridge who has one line: “There’s an unscheduled departure” after which he gets whacked off by Finn in his Tie Fighter].
