“I realized the history [behind Columbia’s creation] would be fascinating to someone in Cumberland or someone in Ocean City – not just the people of Columbia,” he said of his focus on Rouse, who died in 1996.

Day said he worked on the documentary as a “one-man band” instead of utilizing a team approach, and created the film by editing down 20 to 30 hours of footage, “which is not atypical.”

One of his best decisions, he said, was to hire Keith David as the film’s narrator.

David is an Emmy-winning voice actor who has narrated such documentaries as “The War” and “Unforgiveable Blackness” for filmmaker Ken Burns. He’s also a movie actor who’s appeared in “Platoon” and “The Thing.”

David has a rich, full baritone that embodies the sense of history being made, Day said.

But the linchpin of the documentary, Day said, is the 1987 interview videotaped by Scott Kramer, a multimedia specialist with the Howard County government.

Kramer had persisted for years in asking the camera-shy Rouse to sit down with him and talk about Columbia before Rouse finally relented.

“That video was a godsend,” Day said of the 90 minutes of footage. “I used a lot of it in the film because I wanted [the story] to come out of Rouse’s mouth.”

Kramer, who collaborated on the video with Deborah Hurley, dubbed their video — with its tight shot of Rouse’s lined face, round glasses and bushy eyebrows — “the Holy Grail of interviews.”

“Jim was a very humble person who didn’t like to toot his own horn,” he said.

“We just started out by asking him, ‘Can you just tell us stories?’ “He was very sharp and he was at his peak, and we were both in awe of everything he talked about,” said Kramer, who’s grateful portions of the interview appear in the film. “That video is priceless to us.”

Day also tracked down — in what he described as “a grand scavenger hunt” — a 1966 public TV documentary called “Rise of the New Towns” that was made by the National Education Radio and TV Network, which eventually became WNET.

“The footage of Rouse and his lieutenants discussing how the city would be wasn’t in their vaults,” he said. “I found it at the University of Indiana at Bloomington in a queue waiting to be digitized.”

Robin Emrich, archivist with the Columbia Archives since 1998, viewed the film Tuesday with her Columbia Association colleagues and was impressed with Day’s approach and tenacity.

“I was over-the-top about it,” she said hours later, adding it was “very emotional” to watch.

“The documentary is a wonderful tool that uses primary-source materials to convey how unique this place was and is,” she said. “This film is for people who think they know Columbia history and for people who don’t.”

Olsen, who grew up in Laurel, agreed.

The Rouse biographer, who is now a Washington real estate executive, pointed out that in the1960s a number of new towns were being started in the United States with varying degrees of success.

“Columbia is certainly interesting in the broader context of Maryland history since it’s the state’s second-largest city — nowhere as big as Baltimore, but bigger than Annapolis or Frederick.

“It’s remarkable how much ground Ken was able to cover in one hour and how the film goes beyond the physical planning and gets into the social institutions of Columbia,” he said.

Tennenbaum, an original Rouse Co. lieutenant who appears in the vintage video incorporated into the documentary, pointed out that Columbia didn’t become financially successful until the 1980s.

“It’s very difficult to the tell the story of Columbia without the context of history and the economic times, but Ken did a terrific job on that,” he said.

East, who now works for Columbia Association in community services, was equally impressed with the final product.

“It was very touching to hear Jim’s voice and so powerful to listen to him articulate his dream,” she said.

“But it’s what he embedded in our hearts and souls about what cities can be” that stands out in Rouse’s legacy, East said. “At the end of the documentary you can’t help but think about the value of creating better places to live.” janeneholzberg76@gmail.com
