Comic-Con 2013 was another megastar-filled extravaganza -- with some of the biggest celebs from TV and film invading San Diego to announce a ton of HUGE news.

If you weren't one of the 130,000 people who attended this year's convention, don't worry.

While some of the studios keep the footage they debut on lockdown for months, others are more generous to fans who couldn't afford to fly to Southern California for the weekend. 

Brand new trailers for "The Hunger Games," the "Veronica Mars" movie and "The Walking Dead" all made it online shortly after their Comic-Con premieres -- and new info about top-secret films like "X-Men: Days of Future Past," "Guardians of the Galaxy" and a new "Avengers" sequel has been trickling in.

Check out 10 Things from Comic-Con You Can't Miss below!

1.) Loki Takes Over Hall H

Chris Hemsworth
 didn't show to promote "Thor: The Dark World," but fans in Hall H got one better: Loki, live in person!

Tom Hiddleston actually dressed up as his "Avengers" bad guy and whipped the entire audience into a frenzy -- demanding they kneel and repeat his name. The video is amazing, just watch it above!

2.) The Dark Knight is Coming Back 

While Christian Bale probably won't be back, Warner Bros. announced that Batman will appear in the "Man of Steel" sequel, expected in 2015. 

The Hall H panel included a reading from Frank Miller's "The Dark Knight Returns" and a video showing Superman's logo superimposed on the Batman logo.

No other details are available, but it's clear Warner Bros. is starting to form their own "Avengers" team -- leading to an eventual "Justice League" flick.

3.) Mulder & Scully, Together Again! 

"The X-Files" premiered on FOX 20 years ago this September -- and to celebrate, Gillian Anderson and David Duchovny made their first Comic-Con appearance together ever during a TV Guide-hosted panel.

The two reminisced on working together on the long-running show and it's clear the chemistry between them is very much alive. Could we see a new movie in the future? The stars are game -- and creator Chris Carter said the fan turnout for their panel was very "inspiring."

4.) New Details from "The Avengers" Sequel Emerge


Joss Whedon appeared at the very end of Marvel's Hall H panel, revealing the official title of his followup to the ridiculously successful 2012 flick. "Avengers: Age of Ultron" is due in 2015.

In the comics, Ultron is a big bad robot hellbent on destroying humanity, but Joss tells Marvel LIVE that he'll be changing the villain's origins for the movie -- saying "We were crafting our own version of it where [Ultron's] own origin comes more directly from the Avengers we already know about."

Whedon also says the movie will be "darker" than its predecessor.

 5.) Happy Hunger Games ... Again

7.) All 700 X-Men Take the Stage

In one of the weekend's most impressive moments, 20th Century Fox managed to get almost every star of the sure-to-be-epic "X-Men: Days of Future Past" to show up for the film's surprise Hall H panel.

With the movie starring both original trilogy stars and the actors from "X-Men: First Class," that meant Hugh JackmanHalle BerryAnna Paquin, Jennifer LawrenceSir Ian McKellenPeter DinklageSir Patrick StewartShawn AshmoreNicholas HoultEllen PageMichael FassbenderJames McAvoy and Evan Peters were all there.

Everyone's favorite teen detective is back on the case -- but the kids of Neptune High are all grown up now.

Kristen Bell and the rest of the show's cast showed up to promote their new Kickstarter-funded flick, giving fans their first look at footage. 

Showing the gang getting back together for a high school reunion, the trailer is full of snappy dialogue, embarrassing dancing and one hell of a punch from the title heroine. We can't wait!

9.) "Guardians of the Galaxy" Blows Everyone Away

They've only been filming for 13 days, but the footage from Marvel's upcoming "Guardians of the Galaxy" impressed everyone who saw it. Sadly, we can't show it here -- but the film's comedic tone and ridiculous characters (like a machine gun-wielding raccoon) were a hit.

Marvel also confirmed the film's final cast: Chris Pratt as Star-Lord, Zoe Saldana as Gamora, Dave Bautista as Drax the Drestroyer, Karen Gillan as Nebula, Djimon Hounsou as Koranth, Michael Rooker as Yondu, Lee Pace as Ronan the Accuser and Benicio del Toro as The Collector.

10.) Jesse Makes Out with Heisenberg

The panel for "Breaking Bad" opened hilariously -- with Bryan Cranston walking out wearing a mask of his bald, onscreen alter-ego. 

After removing it and placing it on the table, Aaron Paul decided to slip it some tongue. It was definitely a wild way to kick off the presentation, which included a look at the first minutes from the show's final season.

According to EW, it involves a flashforward ... and a skatepark "in the unlikeliest of places."
