10 things you missed in the new 'Star Wars: The Last Jedi' trailer

The latest "Star Wars: The Last Jedi" trailer doesn't reveal too much, but there are some clues as to what is happening. It looks like Kylo Ren and the First Order have returned to a familiar planet, and Finn may be going undercover in a First Order uniform. And did you catch those new walkers? Following is the text of the video.

Warning: Possible spoilers ahead.

Kylo Ren's scar from "The Force Awakens" has moved. Director Rian Johnson didn't like the old placement. Now it goes across his eyebrow instead of his nose. The scar is similar to Anakin's. These aren't the same AT-ATs from "The Empire Strikes Back." They're the AT-M6 - All Terrain Mega-Caliber Six. They have a weird kind of hand-foot that may prevent them being taken down by rope. These troopers may be on Mustafar - the planet where Obi-Wan took down Anakin. It's also the home of Darth Vader's castle in "Rogue One." We're going to come back to this scene in a bit... There are rumors of a "force tree" Rey will have to enter. Similar to the one Luke entered on Dagobah. Is this it? Rey may find The Journal of the Whills. A history of how the Jedi came to be. This may also be the first Jedi temple - which Han said Luke went looking for in "The Force Awakens." This is probably a flashback - to Kylo Ren burning Luke's Jedi academy. This looks like Kylo Ren is firing on his mom's ship. "Let the past die. Kill it, if you have to." Finn is fighting Captain Phasma while wearing a First Order uniform. Snoke is torturing Rey in the same scene we saw Kylo Ren earlier. These are the robes of Snoke's guards. Kylo's grey band-aid is gone by the end of the trailer. "The Last Jedi" opens Dec 15, 2017
