According to 72 U.S.C. § 403(c)(2)(C), we must show you new Star Wars trailers as soon as they are released, and breathlessly discuss the implications of the 1.5 seconds of actual new footage.

At the beginning of this trailer, you see what looks like a sci-fi Nuremberg rally full of Stormtroopers. Standing in front of them are a collection of officers, led by one extra-evil seeming guy. One of these officers is (probably) Gwendoline Christie from Game of Thrones, who will be playing Captain Phasma. One of the other officers is General Hux, played by Irish actor Domhnall Gleeson, best known as Bill Weasley from the last Harry Potter films. Standing at center is (again, probably) Andy Serkis playing Supreme Leader Snoke. Collectively, the officers and the soldiers form The First Order, a group that has risen from the ashes of the Empire.
