The undisputed kings of heavy metal, Metallica, made their very first appearance at San Diego Comic-Con today. All four members of the icon band – James Hetfield (vocals, guitar), Lars Ulrich (drums), Kirk Hammett (lead guitar), and Robert Trujillo (bass) – came to the convention center’s Hall H to promote their upcoming 3D film, Metallica Through The Never. Director/writer Nimród Antal (Predators) and producer Charlotte Huggins (Journey to the Center of the Earth) also appear on the panel, which revealed the world premiere of the film’s theatrical trailer and poster, as well as exclusive preview footage.

Check out the theatrical trailer and poster here below.

The movie stars the band in concert performance sequences, along with actor Dane DeHaan (from The Amazing Spider-Man 2) as Trip, a roadie who is sent on an urgent mission to pick up a bag during one of the band’s sold-out shows. Tripp’s mission gets diverted after his van crashes; when he emerges from the wreck, the city seems to have gone mad, with rioting and a masked horseman riding through the streets hacking at and lassoing the citizens. But Tripp still has his job to do and the audience is left to wonder, what’s in the bag?

What would the 2013 version of San Diego Comic-Con be without an appearance by the Amazing Spider-Man, and an appearance by Spidey is just what we got Friday at the convention center. Director Marc Webb was on the panel to show off a bit of footage from The Amazing Spider-Man 2, which is still in production. Along for the ride with Webb was his leading actor, Andrew Garfield, who came out dressed in full Spider-Man gear. Dean DeHaan who plays Harry Osborne was also there, as well as producers Avi Arad and Matt Tolmach.

Emma Stone had a brief video message that was interrupted by Electro. Then, in a surprise moment, Jaime Foxx came out on stage to some huge applause. Garfield went on to play the beginning of the panel in character as Spider-Man, getting asked a bunch of hero-related questions. A few minutes in, Spider-Man got called away on urgent business, leaving room for Garfield’s proper entrance.

Anticipation for the RoboCop remake has been hit or miss since the project was announced, which made the Sony/Screen Gems panel at San Diego Comic-Con today the first big chance the filmmakers had to get everyone on their side. On hand to talk about the film were director Jose Padilha, and actors Joel Kinnaman (The Killing), Abbie Cornish (Sucker Punch), Michael Keaton, and fan favorite Samuel L. Jackson.

The panel started with a solid 5-minute clip showing Samuel L. Jackson as a TV host, sending out a broadcast showing some ED-209’s in action in the Middle East, while Michael Keaton’s character tries to convince members of the government that robots can be used as police instead of humans.

Director Jose Padilha explained that he wasn’t going to attempt to do the same movie that came out in 1987, but wanted to take elements and put them in a modern context where combat drones are a very real thing.

The first Cloudy With a Chance of Meatballs was a surprising hit at the box office, paving the way for an inevitable sequel. Sony Pictures Animation brought the sequel’s crew and stars to San Diego today to meet the Comic-Con audience.

The panelists Cloudy With a Chance of Meatballs 2 included stars Bill Hader, Anna Faris, and Terry Crews along with directors Cody Cameron and Kris Pearn. Ralph Garman moderated the Sony panel. Andy Samberg, Kristen Schaal, and Will Forte also star with Hader, Faris, and Crews, and were featured in a pre-panel clip showing the actors attempting to cosplay as their animated characters.

We all know that everyone is looking for the next film series to match the success of the Twilight movies, and that’s what Sony Pictures seems to be going for with The Mortal Instruments: City of Bones. The film is based on Cassandra Clare‘s series of young adult novels, and Clare was on hand at San Diego Comic-Con today to introduce the film to the crowd in Hall H and show off some exlusive footage. Joining here for the panel were director Harold Zwart and actors Lily Collins, Jamie Campbell Bower, Robert Sheehan, Godfrey Gao, and Kevin Zegers.

The panel started off with Lily Collins talking about her character and explaining her motivations of finding her character’s mom. Collins said that she was a fan of the books before she was cast in the movie.
