Metallica Rock Comic-Con

Metallica unveiled the trailer and poster and previewed one scene from Through the Never at their 45-minute Comic-Con panel on Friday -- then played a 13-song concert at Spreckels Theater in San Diego for those lucky enough to win tickets.

The four band members were joined by the film's director, producer and star Dane DeHaan to answer questions about the upcoming film, which weaves a story line around footage of Metallica playing in concert on a special stage that features references to visual milestones from their history.

In their answers, the panelists said that they feel the 3D film will be a unique contribution to rock cinema, though drummer Lars Ulrich added that for it to be considered in the same league as such films as The Who's Tommy and Pink Floyd's The Wall "would be amazing." Both Ulrich and frontman James Hetfield spoke about the two-year odyssey they've been on to complete the movie and how they focused on the film over all else during that time. Hetfield also hinted that they might make further use of the stage after the film's release.

Ulrich also said that Metallica really have nothing left on their plate once the film has been released and promoted, so 2014 will be devoted to recording their 10th studio album.
