20 Movie Reveals That Must Happen At Comic-Con 2016
12. Thor: Ragnarok Footage Or Concept Art
Thor: Ragnarok began production on July 4. That's cutting it awfully close to SDCC, but Marvel showed Guardians of the Galaxy footage after just 12 shoot days in 2013, so we can't rule it out. One key member of the cast will already be there if Marvel wants someone to introduce the crowd to Ragnarok.
Tom Hiddleston will already be in town for Warner Bros.' Kong: Skull Island panel earlier that same day. Marvel could have him stick around and maybe even fly in Chris Hemsworth, Mark Ruffalo, and/or director Taika Waititi for an appearance. If Marvel doesn't want to spring for flights, it can just rely on Hiddleston or have the crew provide a video message.
Marvel likes to exceed expectations at Comic-Con, so it will not be a surprise at all if the studio at least shows new concept art even if there's no footage ready to be shown. We will know more about Thor: Ragnarok on July 23 than we knew on July 22.
