In an exciting announcement that has already sent shockwaves through the sports community, Netflix has revealed plans to release “The Underdog”, a compelling documentary about the life and legacy of New York Yankees legend Lou Gehrig. Set for release on September 2, 2025, the documentary promises to offer an in-depth, never-before-seen look at Gehrig’s remarkable career, personal life, and the disease that ultimately claimed his life.
“The Underdog” aims to tell the story of Gehrig’s journey from his early days as the son of German immigrants to becoming one of the most celebrated figures in baseball history. Known as the “Iron Horse” for his record-breaking streak of 2,130 consecutive games played, Gehrig’s career was nothing short of legendary. However, his story extends far beyond his athletic feats. The documentary explores his tragic battle with ALS (Amyotrophic Lateral Sclerosis), a condition that would not only cut his career short but also forever link his name to the disease, which is now commonly referred to as Lou Gehrig’s disease.
A Deep Dive Into the Life of a Baseball Icon
“The Underdog” promises to deliver unprecedented access to Gehrig’s life, bringing to light rare footage, new interviews, and intimate stories that have never been shared before. Family members, former teammates, and baseball historians contribute to a multifaceted portrayal of the man behind the legend.
The documentary will highlight key moments of Gehrig’s stellar career, including his legendary partnership with fellow Yankee Babe Ruth, their iconic “Murderers’ Row” lineup, and his undeniable impact on the team’s dynasty in the late 1920s and 1930s. But beyond the statistics, the film also delves into the quieter, more personal aspects of Gehrig’s life—his relationship with his wife Eleanor, his struggles with the early symptoms of ALS, and his emotional farewell speech on July 4, 1939.

A Legacy That Transcends Time
Perhaps what makes “The Underdog” so special is its ability to connect Gehrig’s story to contemporary issues, most notably the fight against ALS. The documentary not only recounts the life of this remarkable athlete but also reflects on the ongoing impact of his legacy in the fight against ALS. In addition to family and friends, modern-day athletes and figures in the ALS community discuss how Gehrig’s bravery and resilience have influenced their own lives and the broader awareness of the disease.
“The film is about more than just baseball,” says Netflix Executive Producer Sarah Clarke. “It’s about how one man’s courage can change the world, how Gehrig’s story transcends sports and continues to inspire millions in their own battles, whether on the field or in everyday life.”
Never-Before-Seen Footage and Interviews
One of the most anticipated aspects of the documentary is the exclusive content it will feature, including rare archival footage from Gehrig’s early days in the major leagues and personal films that have been kept private for years. Interviews with Gehrig’s widow, Eleanor, offer an intimate look at their life together, while former teammates such as Yogi Berra and Joe DiMaggio reflect on Gehrig’s impact both on and off the field.
Additionally, the documentary will explore Gehrig’s role in shaping the Yankees’ culture and how his story continues to resonate with today’s athletes. Current Yankees players will share their thoughts on Gehrig’s influence and how his legacy has remained a key part of the team’s identity.
A Timely Release for Baseball Fans
With the upcoming release of “The Underdog”, baseball fans are in for a truly remarkable experience. Scheduled to drop on September 2, 2025, the documentary will coincide with the 84th anniversary of Gehrig’s historic farewell speech, which took place at Yankee Stadium on July 4, 1939. The speech, where he famously said, “Today, I consider myself the luckiest man on the face of the Earth,” continues to echo across generations as a testament to Gehrig’s unshakable spirit.
Netflix has also promised exclusive behind-the-scenes content leading up to the documentary’s release, as well as a special edition of Lou Gehrig Day on social media platforms. Fans can expect an immersive experience that brings the documentary to life through interactive content and special screenings.
An Event for Baseball and Beyond
“The Underdog” is set to be more than just a documentary; it’s an event. As baseball fans prepare to celebrate Gehrig’s enduring legacy, the documentary will serve as a powerful reminder of the strength of the human spirit and the profound impact sports figures can have on society at large.
For current fans, and those discovering Lou Gehrig for the first time, this documentary offers an unmissable opportunity to witness the life of a man who truly embodied what it means to be a legend. His story, which continues to inspire millions, is about perseverance, heart, and an unwavering commitment to greatness—qualities that will be celebrated for generations to come.
