GALLERY: Comic-con's big highlights

Every year, around 130,000 comic book fans and entertainment enthusiasts trek to San Diego's Comic-Con International, where thousands of booths and hundreds of panels are set up by industry outlets to cater to attendees.

The realm of Middle Earth and caped superheroes brought adventure and battle to Comic Con, as fans of Warner Bros' The Hobbit and Batman v Superman were treated to first-look sneak peeks of the films on Saturday.

The eager audience at the convention, most of whom had camped out overnight to get into the 6,500-capacity hall, were treated to a 10-minute blooper reel of main actors on Lord of the Rings and The Hobbit messing up their lines and goofing around on set.

Benedict Cumberbatch plays two characters in the upcoming Hobbit film - the dragon Smaug and the Necromancer, an iteration of villain Sauron.

"One is made of something vulnerable and one seems to be born out of everything that's evil and difficult to pin down and kill," Cumberbatch said.

The other big highlight of the Warner Bros panel was the highly anticipated glimpse at Man of Steel sequel Batman v Superman: Dawn of Justice. Director Zack Snyder showed a 30-second clip of Batman, played by Ben Affleck, flaring the bat signal into the sky, only to find the silhouette blocked by Superman, played by Henry Cavill.

Snyder brought Affleck, Cavill and Gal Godot, who plays Wonder Woman on stage, but did not reveal anymore about the plot of the film, due out in theaters in 2016.
