Ben Affleck is a real Renaissance man. The Oscar-winning screenwriter and famous actor graced the halls of Georgetown Loews on Thursday night for the D.C. premiere of his new film, “Gone Baby Gone,” which marks his directorial debut.

One thing Affleck doesn’t have on his resume? Politician, though not for lack of gossip. Rehashing ancient rumors that he was planning to run for governor of Virginia made the actor laugh, and he brushed off a question about plans to run for congressional office with a wan smile. “There must be better people,” he said.

Also on hand for the premiere was Affleck’s younger brother, Casey, who stars in the thriller about the hunt for an abducted child, set on the streets of — where else — Boston.

The younger Affleck said he had a soft spot for D.C. — he bummed around the city for a year as a directionless 20-year-old about 12 years ago. Any favorite places? Lots, he said, but he was only in town for the day. He spent it strolling through Georgetown.

During the screening, the Brothers Affleck grabbed dinner at Agraria on the Georgetown waterfront, before heading up the hill to the Capitol File after-party at the City Tavern Club.
