"It seems that Laura Dern is a leader of The Resistance.
Leia’s ship is ambushed, she is blasted through space.
Leia ends up in a coma. Laura Dern’s character then takes over Resistance command, but makes things far worse.
With this in mind, Poe takes control of the situation and becomes the interim leader of The Resistance."
I’m not sure how reliable this info is, but it’s an intriguing idea.
PS, I can’t remember anyone having posted this photo from Dubrovnik earlier;
It looks like Finn, and maybe Rey, riding some animatronic cat-horse thing. I’m assuming that that metal pole sticking into it’s “guts” is connected to the inner mechanics and that it’ll be removed digitally in post.
So it’ll be interesting to see this thing in action in the film. Hopefully, it’s a bit more active and on screen than the Jakku pig-thing from TFA.
EDIT: I think I can see a wheel as well attached to the front of the whatever-it-is.
