8 Fan Bases That Need to Pay Attention to Comic-Con

The Once Upon a Time cast will hit the Comic-Con scene once again pre-season-three, and the show's panel usually has fun goodies like videos and cute banter between the stars (like now-married Josh Dallas and Ginnifer Goodwin). But what we really want to catch in the panel is any word on the upcoming Frozen crossover, especially now that we've seen Elsa on the set!

We're in the middle of True Blood's final season, and given that the show's cast always delivers a hilarious and raucous panel, this year's is likely to be the best — and most emotional. There will probably be new footage of the rest of the season, maybe someone will spill about Sookie's romantic fate, and surely someone will ask Alexander Skarsgard to take his shirt off.

If you love any of the Avengers and can't wait to find out which Marvel comic the studio will bring to the big screen next, then pay attention once the comic giant hosts its panel in Hall H. Past panels united the Avengers for the first time and have given fans the first glimpse at trailers and footage, so you won't want to miss out on all the insider fun.

The Vampire Diaries is also a panel that is always fun at Comic-Con, and this year should be even more interesting because of the happenings of the season finale. Will Ian Somerhalder even be there? Will he give more hints that Damon is still alive? Hopefully we get some answers this weekend.
