'Hero's cutie Hayden Panettiere plays baseball on the set of her new film 'Fireflies in the Garden' in Texas. The film plot so far from IMDB.com is pretty thin is loosely based on director Dennis Lee's life and "explores the complexities of love and commitment in a family torn apart when faced with an unexpected tragedy." This a huge step for Hayden's career as the film boasts an all-star cast including Julia Roberts, Ryan Reynolds, William Dafoe, Carrie-Anne Moss, and Ioan Gruffudd. More pics after the jump!
