Freedom River (1971)
As relevant as FREEDOM RIVER was in Vietnam-era United States, I’d wager its message is even more relevant in our day and age. The film’s heavy tone is tempered by spare and appealing production design by Bernie Gruver. Other credits include narration by Orson Welles, direction by Sam Weiss (THE ALVIN SHOW, ROGER RAMJET) and animation by Vincente Bassols. The film was produced at Stephen Bosustow Productions.
