Jennifer Garner looked chic and sleek in her monochromatic white top and black skirt at The Kingdom premiere in Tokyo today. That's quite the opposite of how she felt while actually making the film. "I had heat stroke — twice," she told Access Hollywood. "I was still breast-feeding my baby [Violet] at the time. Everything your body needs, all the electrolytes goes to the baby, and so my system was all screwed up." But that wasn't about to halt production: "They gave me an IV, filled me back up and sent me back out," recalled Jen. What a trooper!
