"What's my goal with the green flag?" Chris Hemsworth said one year ago, repeating a question shouted by a sweaty race fan pressed against the fence that lines the legendarily long front-stretch grandstand of the Indianapolis Motor Speedway. "Same as with my hammer," the actor known as Thor answered. "I hope I am worthy enough to hold it ... and not, you know, drop it into the middle of the Indianapolis 500."
Moments later, as the field of 33 race cars roared by beneath him, Hemsworth proved he was indeed worthy of the task. He flicked his wrist just as he'd been instructed and whipped the green cloth firmly -- and safely -- to start the 102nd running of the Greatest Spectacle in Racing.
