I was sitting in the audience with Tobar when this was shown at the Gareth Edwards panel (unfortunately, Josh Trank was sick, or who knows what we would have seen). It looks fantastic. They're bringing in people who worked on movies like Black Hawk Down, Saving Private Ryan, and Zero Dark Thirty, so I feel like that's the tone we can expect from this gritty, "real" war movie that relies on the heroism of real people and not magic Force users.
The teaser was fantastic. Jungle planet (or moon), TIE fighter, the Death Star reveal... All set to Old Ben's monologue about how the Jedi were the guardians of peace in the galaxy before the Empire... A subtle bit of the Imperial March as the music hits it's crescendo... Chilling! Can't wait for more of it.
