Sans beau Brad Pitt, Angelina Jolie wowed the crowd Thursday at the annual fan convention Comic-Con in San Diego, Calif.

Clad in a fitted Versace biker jacket over a black pencil skirt, the actress, 35, sat on a panel to discuss her new action-thriller Salt (out Friday).

She recalled how she took a bad spill performing one stunt -- and got freaked out afterwards when she couldn't hear anything.

"I thought I'd had a concussion, but I had forgotten that I had my earplugs in from [shooting] the gun!" she said.

The Oscar-winning actress famously replaced Tom Cruise in the movie about a CIA officer falsely accused of being a Russian agent.

Compared to her past thrillers like Wanted and Tomb Raider, Jolie said Salt is "a better action movie." She said her "style got meaner and harder and darker ... it wasn't as pretty."

Another bonus of shooting Salt: "I got to play with just about everything," she said, "including using a fire extinguisher in a way I'd never used it."

Pitt, 46, was expected to attend Comic-Con to promote his kiddie flick Megamind at the DreamWorks Animation film's panel.

But director Tom McGrath joked, "Unfortunately, since Angelina's here, Brad had to watch the kids."
