Okay, now it's the Warners panel. http://batman-news.com/2015/07/11/batman-v-superman-comic-con-hall-h-live-blog/ They're shooting the shit about "Man From U.N.C.L.E.". Don't care, get to BvS.
Good call by Disney to keep Marvel away - this is Star Wars moment and they are doing it very, very well.
Confirmed, Holly Hunter plays a senator. Dunno why they were so top secret about that, sounds like a minor character.
I'd forgotten how much Holly Hunter's accent grates on my nerves, she's like a Southern version of Fran Drescher, IMHO. Still, it looks like an awesome flick. (Is it just me, or is Jeremy Irons starting to sound more and more like Boris Karloff?)
