#SDCC #ICYMI: Comic-Con Day 3 Social Wrap

Saturday's panels at Comic-Con might've been the biggest yet. Between the assembled "X-Men: Days of Future Past" and surprise "Guardians of the Galaxy" cast appearances at the Marvel panel (as well as a visit from Tom Hiddleston in character as Loki), the news of a Batman vs. Superman film face-off, and of course, the debut of the theatrical trailer for a little movie named "Catching Fire," there was a lot of news coming out of San Diego today.

So, we've filtered through the star sightings and big reveals to bring you the buzziest bits out of Saturday's showings. Strap in, folks — Day 3 was nothing short of epic.
