Good gracious, the stars are piling up like planes over Hartsfield-Jackson.  Ryan Reynolds and Jason Bateman are back in town to do a little more work on "The Change-Up," which comes out in August. The project, which filmed all over town last year, set up shop at Phipps Plaza Sunday. During a break in the action, Reynolds and director David Dobkin had lunch at Davio's Northern Italian Steakhouse in the mall. A few tables over sat  Billy Bob Thornton, who's here working on his film project "Jayne Mansfield's Car." Also Sunday, Kevin Bacon and Sean Hayes stopped by the set to say hello. Hayes is here shooting "The Three Stooges," which has moved to Cartersville after filming at the Boisfeuillet Jones Atlanta Civic Center. Bacon's here for "Jayne Mansfield's Car," which is filming in Cedartown. Anyway, while all this was going on at Phipps Sunday, Robert Duvall, who is also here for "Jayne Mansfield's Car," was across the street at New York Prime. He's become something of a regular, dining at the clubby steakhouse three times in just the past week or so.  He and his wife also like the Buckhead Diner, and had lunch there Saturday. And finally, even though Atlanta's no longer a hockey town, filmmakers Peter and Bobby Farrelly, the guys behind "The Three Stooges," found the perfect spot to watch the NHL championship the other day:  Stooges Sports Bar on Howell Mill Road.
