Last year it was Thor, and now it's Batman. Who will do a better job at waving the flag?. Hollywood actors Matt Damon and Christian Bale will wave the green flag come Sunday, May 26 to kick off the 103rd running of the Indy 500, but before they do that, three-time Grammy Award winner Kelly Clarkson will sing the National Anthem to nearly half-million race fans congregated at the Indianapolis Motor Speedway.
