The show was filming at the Liriodendron Mansion in Bel Air and elsewhere in west Bel Air on Tuesday afternoon, where filming also took place Monday night, according to Town of Bel Air Economic Development Director Trish Heidenreich.
More filming is expected early next week in the Edgewood area, Eileen Frado, senior business development associate with the Harford County Office of Economic Development, said Tuesday.
"It will be an outside shot on a road, although I am not at liberty to say where that is," Frado said.
Frado, whose office is working with the production company, said they are looking for other locations in Harford to shoot scenes for the second season of the Capitol Hill political drama that stars Kevin Spacey and Robin Wright. Both are nominated for acting Emmys for the show's first season last year.
"They had expressed to me, and I have certainly seen it myself, where they are filming as much as they can in Harford County close to their set in Joppa," Frado said.
Heidenreich, meanwhile, had brought up the Liriodendron filming during the Bel Air Board of Town Commissioners meeting Monday night.
"We are hoping this is just the beginning of something wonderful for the town," Heidenreich said Monday.
Casting calls for "House of Cards" have been held Bel Air Record Armory this year and last, and many of the show's interior shots have been filmed on a sound stage inside a building in the Joppa area, where the production is based. The production company also has an office in Edgewood, according to Frado. The locations of both have been closely guarded secrets since the production set up shop in the county.
Some outdoor scenes for the first season were filmed in and around the Havre de Grace, which doubled as Kevin Spacey's character's hometown in South Carolina.
Heidenreich noted the film crew takes advantages of Bel Air restaurants and shops, helping out the town economically.
Bel Air Mayor Edward Hopkins agreed.
"They have already got all their stuff set up at Liriodendron," he said, adding it is good that Bel Air can get some national exposure.
Mario Buontempo, co-owner of the Main Street Tower in downtown Bel Air, said the first level of the restaurant and lounge, including the banquet room and dining room, was being used Tuesday by the cast and crew for meals, dressing rooms and to hold meetings.
"It is quite a bit of people there from Hollywood," Buontempo said.
Buontempo, who estimated about 180 people from the production were using his establishment, said the Tower has remained open for regular business.
He said "a lot of famous movie stars" had been in the Tower, but he could not reveal who they were, in accordance with an agreement he has with the production company.
"I did see a lot of movie stars in the main dining room today," he said. "[They're] very impressive; they say, 'Hi,' nice people."
Buontempo also thanked Bel Air Police Chief Leo Matrangola for coordinating parking with the production so it did not affect business at the Tower.
Production vehicles could be seen in the town-operated lots behind the Tower.
