While brother Ken Burns was redefining mammoth entertainment with his public television events, brother Ric was creating tighter, more definitive documentaries such as The Donner Party, whose tragic subject has seemed more a punch line than a historical event. Yes, members of the Donner party ate human flesh when they were caught snowbound in the Sierra Nevadas just 150 miles away from the end of their 2,500-mile trip across the United States in 1846. But there's more to the story, and Burns uses the customary array of old pictures, current landscapes, and readings of historic dispatches and letters by actors (including Timothy Hutton, Amy Madigan, and Eli Wallach) to create a vivid portrayal of the pioneers' tough life. The heartbreaking circumstances of and miscues by the Donner party turned a common migration into one that is remembered as a landlocked Titanic tragedy. What if the snow had come one day later? What if the winter was not the worst on record? And most importantly, what if Lansford Hastings had not advertised a "shorter" West Coast route that he had never seen? Other details bring to light the human achievement of the survivors, including the intriguing fact that the women and children survived in greater number than the men. Anchored by the eerie music of Angelo Badalamenti's "Dark Spanish Symphony," the film constructs the fate of the Donner party as the gloomy side of the American dream. --Doug Thomas
