Hollywood is set to host the premiere of the compelling documentary, 'Undeniable Evidence: Clean Medicine. Dirty Politics.', this Saturday, February 28, 2026. The film will screen at the iconic TCL Chinese Theatre in Hollywood, California, starting at 10:00 a.m. This highly anticipated event will shine a spotlight on the controversial and often-debated efficacy of hyperbaric oxygen therapy (HBOT) for traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD).

Directed by U.S. Army veteran John Salcedo, the documentary delves into the scientific data supporting HBOT and questions why this potentially life-changing treatment faces significant institutional barriers. The film features pioneering HBOT researcher and clinician Dr. Paul G. Harch, Medical Director of Harch Hyperbarics, who has advocated for expanded use of the therapy for decades. Dr. Harch, alongside Salcedo and Juliette Lucarini Harch, is a creative force behind the project.

Following the screening, Dr. Harch will present a 20-minute medical lecture focusing on individualized dosing in hyperbaric oxygen therapy. 'Undeniable Evidence' has already garnered critical acclaim, winning Best Documentary at the Syracuse International Film Festival and receiving a nomination for Best Documentary at the MV Shorts LA Film Festival. It was also selected for the Golden State Film Festival. The film previously premiered at the National Press Club in Washington, D.C. on November 18, 2025.
