Comic-Con 2013 wraps up with "Hunger Games," Marvel and more

Comic-Con 2013 came to an end Sunday after four days of panels for fan-favorite movies, TV shows and more.

The weekend portion of the annual San Diego convention included events for anticipated movies like "The Hunger Games: Catching Fire," "X-Men: Days of Future Past" and "Guardians of the Galaxy," as well as TV shows like "Breaking Bad," "Community," "Doctor Who" and CBS' "How I Met Your Mother."

Read on for highlights:

"The Hunger Games: Catching Fire":
Jennifer Lawrence, Liam Hemsworth, Josh Hutcherson and Lenny Kravitz were among the cast members who appeared at the panel, where a new trailer was screened for fans. Read more and watch the video here.

"How I Met Your Mother"
The CBS sitcom made its first and only pilgrimage to Comic-Con over the weekend, bringing cast members Josh Radnor, Cobie Smulders, Jason Segel, Neil Patrick Harris and Alyson Hannigan, as well as co-creators Carter Bays and Craig Thomas and director Pamela Fryman.

After screening a video showing Ted's adult children (Lyndsy Fonseca and David Henrie) begging narrator Bob Saget to wrap up the story and tell them who their mother is already, Bays addressed the format for the show's ninth and final season.

"Everyone is heading off to this wedding, and we sort of have this new framework," he said. "We want to stress the word 'framework,' because we don't want people to think there [will be] four hours of flower arranging. We're always going to be flashing back and flashing forward. Decades will span over the course of this weekend."

"Godzilla"
Stars Bryan Cranston, Elizabeth Olsen and Aaron Taylor-Johnson joined director Gareth Edwards to offer a look at early footage from "Godzilla," which hits theaters next spring.

The footage showed Godzilla battling another giant monster, nearly decimating an airport and sending cities into chaos.

Edwards said he wanted to make this film "all my life" and hoped to make "a modern-day blockbuster that has heart and soul and is slightly artistic also."

The film, which wrapped shooting just days before the Comic-Con appearance, is set for release in May 2014.

"Gravity"
Sandra Bullock landed at Comic-Con.

The actress was on hand Saturday to discuss the new film "Gravity," in which she and George Clooney play astronauts floating through space.

Director Alfonso Cuaron said the two Oscar winners comprise the entire cast.

Bullock spent more than six months physically preparing for the role, which required her to spend dozens of hours in a 9-by-9 foot cube that simulated zero gravity. Other shots required her to be "strung up from 12 wires 18 hours a day."

Cuaron said, "It was a very intense experience for Sandra."

After promoting the film, Bullock said she planned to stroll the Comic-Con convention floor trying to "get free stuff."

Superman vs. Batman?
Superman is coming back, and he may have a caped co-star.

"Man of Steel" director Zack Snyder announced Comic-Con that he was making another Superman film, then dropped a hint it may be with Batman.

He declined to reveal many details, saying the script is just being written, but he invited an actor onstage to read a passage to hint at the story line.

"I am the man who beat you," read Harry Lennox, before an image of the Superman logo, backed by the Batman symbol, flashed on the screen.

"True Blood"
The sex-crazed supernatural residents of Bon Temps are going back to their roots on "True Blood."

The Saturday presentation at Comic-Con for the campy HBO vampire series kicked off with a trailer teasing the remaining episodes of the sixth season.

The fast-moving footage showed Deborah Ann Woll's Jessica and the other locked-up vampires being tormented. Stephen Moyer's Bill wreaked more havoc, and Anna Paquin's Sookie entangled with half-fairy, half-vampire Warlow in a dreamy, bloody haze.

Paquin was joined for the panel by co-stars Woll, Rutina Wesley, Kristin Bauer, Ryan Kwanten, Nelsan Ellis, Sam Trammell, Michael McMillan, Anna Camp and Joe Manganiello, as well as newcomer Rob Kazinsky, who plays Warlow.

Kwanten says the characters' story lines will converge as the sixth season comes to a close.

"X-Men: Days of Future Past"
The entire cast of X-Men thrilled fans by uniting on stage Saturday at Comic-Con.

Ian McKellan, Patrick Stewart, Halle Berry, Anna Paquin, Jennifer Lawrence, Michael Fassbender, James McEvoy, Ellen Page, Peter Dinklage, Hugh Jackman and others made for an impressive panel.

Director Bryan Singer also gave fans a first look at "X-Men: Days of Future Past," which is currently filming in Montreal.

Jackman also promoted his new film, "The Wolverine," which opens next week. The actor called the claw-wielding superhero "the greatest role out there."

"This is two great movies in one," he said. "The fact I'm with everybody here is something I'll never forget."

"Doctor Who"
The question of whom the next Doctor Who will be is still a mystery.

Steven Moffat, who writes the landmark science-fiction story about a traveling time lord, says no one has yet been tapped to replace Matt Smith, who is exiting the role this year.

"We haven't done that yet," he said Sunday when asked at a panel on the show in the cavernous Hall H before a crowd bearing hundreds of sonic screwdrivers and who cheered wildly a trailer for the 50th anniversary show to be aired later this year.

Though fans did not get an answer, they were mollified by the scenes from the trailer that featured Smith with his predecessor, David Tennant, along with Billie Piper as Rose and actor John Hurt, too.

"Community"
"Community" mastermind Dan Harmon is back at Comic-Con -- albeit in cheap Iron Man costume.

"I am billionaire playboy and creator Dan Harmon," he said as he introduced himself to the crowd, channeling Tony Stark. Harmon, who was replaced for the NBC sitcom's fourth season after a clash with then-cast member Chevy Chase, was reinstated for its fifth.

He was also joined on stage by former "Community" producer Chris McKenna and co-stars Danny Pudi, Jim Rash, Nicole Yvette Brown, Allison Brie, Ken Jeong and Gillian Jacobs.

Harmon teased that the new season would feature another animated installment and a follow-up to the fan-favorite episode, "Advanced Dungeons & Dragons."

Marvel Studios
Thor's evil brother, Loki, took over the Marvel Studios presentation at Comic-Con on Saturday.

Lights flashed inside the San Diego Convention Center's largest exhibition hall, and Tom Hiddleston, dressed as Loki, commanded the stage. He called Hall H "a meager palace of Midgard" before showing footage from "Thor: The Dark World."

It opened with an epic battle scene, in which Thor takes down a massive monster, reducing him to a pile of rubble with one swing of his hammer.

The cast of "Captain America: The Winter Soldier" shared footage from that film. It also opened with a dynamic fight scene: Captain America battling a dozen assailants in a glass elevator.

Other highlights included the introduction of the "Guardians of the Galaxy" cast and a peek at "Avengers: Age of Ultron."

"Breaking Bad"
Stars Bryan Cranston, Aaron Paul, Anna Gunn, Dean Norris, Bob Odenkirk, RJ Mitte and creator Vince Gilligan took to Hall H in anticipation of the show's final eight episodes, which begin airing next month.

Cranston walked out in a Walter White mask, bearing the character's now-iconic shaved-head look. He kept the gag going by putting the mask on the microphone and speaking into it, and getting co-star Paul to do the same.

Of the series finale, Gilligan told fans, "I am satisfied by the ending. I hope you will be, too. My writers and I, and everyone in front of the lens and behind it I think is feeling pretty good about it."
