Elektra’s back!

Battling a painful injury that had sidelined her for over a week, Garner helped electrify Las Vegas Saturday at the world premiere of her new action movie, "Elektra."

Walking the red carpet at The Palms Hotel and Casino, Garner told reporters: "I wasn’t feeling well over Christmas. I didn’t know why. I thought I had some kind of infection. It turned out that I had messed up my back a little bit."

The 32-year-old actress, dressed in a sleek, sleeveless black gown, added: "I did get a couple of extra days off on my Christmas break out of the bargain, so it has all turned out OK and I’m fit as a fiddle and ready to get back on the horse."

Garner first brought the comic book character Elektra to the big screen in 2003’s "Daredevil," which also starred Ben Affleck.

Affleck, who has been dating Garner, wasn’t spotted on the red carpet.

Where was he?

The actress smiled and replied, "I don’t know. That’s a good question."

Although Garner had a stunt double, she performed most of her own stunts in the film. The actress said she was physically prepared because of her demanding role on ABC’s "Alias."
