WASHINGTON -- Film crews shot scenes for a movie at Nationals Park Friday.
The movie "How Do You Know?" stars Reese Witherspoon and Owen Wilson. Some Nats season ticket holders are being used as extras in the film.
All of the extras will be paid a nominal fee and are treated to free food.
The filming was expected to wrap up Friday but could extend into Saturday.
Amy Argetsinger and Roxanne Roberts of the Washington Post's Reliable Source are getting frequent calls from Wilson spotters. He had dessert at Georgetown Cupcake earlier this week, and on Wednesday unknowingly crashed a private book party in Georgetown.
But other than the cameras at Nats Park, no one has reported seeing any filming so far.
Columbia plans to spend 14 weeks shooting in D.C.
