She had never acted before but hoped this could be the start of bigger things.

Jeffrey White, of Abingdon, who was crisply dressed with black shades, said he saw the casting call on a commercial.
"I was at home watching TV, so I thought, hey, might as well try out," White said, adding he could see himself playing a lobbyist.

The open call, meanwhile, "wasn't too time-consuming," he said.
Joe Budzynski, of Joppa, said he retired from a state job two years ago and tried out "just for the heck of it, just something to do."

Bel Air town commissioner Rob Reier, who was standing by Heidenreich, said he thought the casting call could only be good for the town.
"I think it's outstanding. Anytime we have an event like that where we can bring people in and showcase the town is really fantastic," Reier said.
