Award-Winning Filmmaker Christina Rose Nears Completion of The Lost Voice, a Documentary on Amazon Pioneer Pola Brückner
Rediscovering a Forgotten Female Filmmaker—and the Hidden History of the Amazon
Los Angeles / Zugspitze Region / Brazil — July 26, 2025 — Westcoast German News readers will be intrigued to learn that award-winning filmmaker Christina Rose is putting the final touches on The Lost Voice, a powerful new documentary tracing the life of her great-grand aunt Pola Brückner (also known as Pola Bauer-Adamara), believed to be the first woman to ever film in the Amazon rainforest.
Produced by MirrorWater Entertainment (MWE), a German-American family-run company based in the Zugspitz Region with offices in Los Angeles and Bethesda, the film explores the enigmatic career of Pola, a once-promising filmmaker whose work—and legacy—have largely disappeared from Germany’s cinema history. Christina Rose’s quest to reclaim Pola’s place in that history leads her deep into Brazilian jungles, archival vaults in Berlin, and even into her own personal reflections as a filmmaker.
Filming began in Brazil on April 29, 2025, and followed the path of Pola’s original 1929 expedition. The team traveled from Rio de Janeiro to Belém and Marajó Island, eventually ending in São Paulo. While retracing Pola’s journey, Rose and her team made a stunning discovery: forgotten railway tracks buried in the jungle, which local historians had no knowledge of until now.
“We found the train tracks Pola described in her book—tracks that people in the region had no idea existed,” Rose shared. “It’s now sparked new historical research in the area. One local historian from Marajó was brought to tears when he learned what we were uncovering.”
The film is inspired by Pola’s rare memoir, Eine Frau ging in den Urwald (A Woman Went into the Jungle), which mixes personal account with possible myth. Christina Rose’s mission is to separate fact from fiction and, in doing so, find truth—not only about Pola, but also about her own identity and purpose as a female storyteller.
“I never expected the emotional and cultural weight this journey would carry,” said Rose. “We’re not just making a film. We’re giving voice to a woman and a legacy that have been lost for nearly a century.”
Production was made possible with the support of Brazilian production partner Grifa Filmes, who assisted both with historical research and local logistics.
The Lost Voice is expected to be completed by the end of 2025 and will begin its film festival tour shortly thereafter. Christina Rose is already known for her series Empowered – Women Shaping the Future, which was recently shortlisted for the Screen International Global Production Awards in Cannes. Her storytelling continues to amplify the voices of women who have shaped—and are still shaping—the world in non-traditional roles.
