Rock legends Metallica will mingle with comic book enthusiasts and fantasy fans at this year's (13) Comic-Con gathering in California.

All four members of the heavy metal band - James Hetfield, Lars Ulrich, Kirk Hammett and Robert Trujillo - will appear at the San Diego event on 19 July (13), when they will introduce their new feature film, Metallica: Through the Never, alongside writer-director Nimrod Antal.

Devotees will then have the chance to win tickets to see Metallica perform at a mystery venue later on that evening.

Metallica: Through the Never, which hits U.S. theatres later this year (13), incorporates 3D concert footage with a plotline featuring actor Dane DeHaan as a young roadie for the group.

Comic-Con 2013 will be held from 17-21 July (13).
