Al Bean remembers well the night in 1948 that his dad got him out of bed to watch downtown Urbana's Flatiron Building burn down. "He looked out of the second story windows of our house and saw the flames downtown," said Bean. His dad grabbed his movie camera, and off they went. "We were there most of the night," said Bean, who was 12 at the time. Now J.M. Bean's movies of the fire provide an exciting segment for a new WILL Channel 12 documentary, "Do You Remember?," which uses old home movies and recollections of residents to illuminate the history of Central Illinois. Premiering at 7 p.m. March 12, "Do You Remember?" also includes film of boy scouts at Camp Drake near Danville around 1932; Bloomington- and Springfield-area footage of the Interurban Railroad, which joined cities in Central Illinois; and film of the "Broomcorn Johnnies," migrant workers who came to the areas around Arcola and Charleston/Mattoon between 1900 and the 1950s to harvest broomcorn. Producer Jeff Cunningham asked people across Central Illinois to lend him their old home movies of the area, and to talk to him about the films they took. Many people, not really knowing what they had, simply went into their closets or attics and brought Cunningham whole boxes of film. He painstakingly viewed it all to look for portions that had historical significance. The result is an evocative portrait of the past, seen through the lenses of old 8mm and 16mm cameras, and filtered by memories of people who were there when the film was taken or who remembered the subject. The segment on the Flatiron Building fire features not only Bean's movies of the blaze, but also of the demolition of the building afterward. His daughter, Vivian Mason, provided the film. Cunningham interviewed Urbana fireman Bud Glenn, who fought the blaze, and John Finfrock, whose father's office was in the Flatiron Building. The brick landmark was situated on the point of land where Springfield Avenue joins Main Street. Cunningham said that after viewing the films he was left with a sense of the constancy and importance of family life through the generations. "If you believe people took moving pictures of things most important to them, what you saw the most of was family," he said. The process made him something of a crusader for the preservation of old home movies. "Even if people don't have landmarks, it's so important that they preserve the film and have it transferred to videotape," he said. Otherwise, he said, they lose not only the visual family record, but the wonderful oral tradition of storytelling that occurs at family showings of the movies. Cunningham, an independent producer working on the documentary for Channel 12, was the original host of the station's monthly magazine show "Prairie Fire," and was the videographer for a recent Channel 12 documentary about archaeological research in Rome. "Remember When," a national documentary on disappearing institutions and landmarks, will air on Channel 12 following "Do You Remember?" at 8 p.m. March 12. "Do You Remember?" wi11 be repeated at 9:25 p.m. March 12 and again at 2:30 p.m. March 19.
