1) Gareth Edwards on full display
Think about the quick scene of the ground level shot looking up at AT-ATs. It’s grounded and it’s muddy. Edwards also loves to use dark interiors with light pouring in and obscuring the outside (the opening part with Jones’ character walking through the hangar bay). He almost sees the darkness exposing the light. As if the dark underbelly of this fledgling Rebellion can expose the ruling Empire. And if we get anything as visually appealing in this movie as the Halo Jump scene from Godzilla, fans are going to be in fits of joy.
2) Gonk droids!
Those lumbering, seemingly useless droids are back again after making a short appearance on Jakku in The Force Awakens!
3) Ben Mendelsohn as Tarkin
This may be the best thing ever. Even though they tease Darth Vader (most likely voiced by James Earl Jones) and it is rumored he is in the movie, Tarkin is going to have a monster-like, menacing villain quality to him worthy of a Peter Cushing performance.
4) Purge Troopers
A tie-in to existing new material from the Star Wars: Uprising game, they are the black-clad troopers with the crazy helmets. According to the new canon, these troopers are like the old Dark Troopers from the EU LucasArts video games. They are elite troops that are utilized by Governors and Moffs. Expect these troopers to be taking direct orders from Tarkin.
