In an exciting development for hockey fans around the world, Netflix has officially announced the release of The UnderDog, a groundbreaking new documentary chronicling the life and career of Washington Capitals legend Mike Gartner. The highly anticipated film is scheduled to debut globally on October 15, 2025, promising to deliver an emotional and inspiring portrayal of one of hockey’s most respected and underappreciated figures.
Mike Gartner, whose career spanned an incredible 19 NHL seasons, is often regarded as one of the greatest players to have never won a Stanley Cup. Known for his blazing speed, remarkable consistency, and unwavering dedication to the game, Gartner left an indelible mark not just on the Washington Capitals, but on the sport itself. With over 700 career goals and a reputation for excellence both on and off the ice, Gartner’s story has long deserved a deeper spotlight — and now, thanks to Netflix, fans will get the full, unfiltered version.
According to early press releases, The UnderDog will feature exclusive interviews with Gartner himself, his former teammates, coaches, hockey analysts, and even family members who provide unique perspectives into his remarkable journey. Viewers will see never-before-seen footage from Gartner’s playing days, including rare clips from his early years with the Capitals, his time with the Minnesota North Stars, New York Rangers, Toronto Maple Leafs, and Phoenix Coyotes, and his emotional induction into the Hockey Hall of Fame in 2001.
In addition to chronicling his on-ice achievements, the documentary will also delve into Gartner’s off-ice contributions — from his influential role in the NHL Players’ Association to his philanthropic efforts within the hockey community. The filmmakers aim to present Gartner not just as an elite athlete, but as a complete human being whose influence reaches far beyond the rink.
Netflix’s official description reads:
“Mike Gartner’s story is about more than just goals and assists. It’s about perseverance, dignity, and the quiet resilience of a man who let his actions speak louder than words. In a world often obsessed with flash and fame, Gartner’s career is a reminder that true greatness comes from humility, hard work, and integrity.”
The project is being directed by acclaimed filmmaker Jennifer McNaughton, known for her previous sports documentaries that include Fire on Ice: The Miracle on Ice Story and Unbreakable: The Steve Yzerman Saga. McNaughton has promised a storytelling approach that “peels back the layers” of Gartner’s career and personal life, aiming to connect audiences emotionally to a man often described as “the ultimate professional.”
“I’ve always been fascinated by athletes who don’t seek the spotlight but instead let their performances do the talking,” McNaughton said in a recent interview. “Mike Gartner’s story is profoundly inspiring, and it’s a story that deserves to be told with heart, honesty, and respect.”
The Capitals organization has expressed immense pride in Gartner’s upcoming feature. In a statement released by the team, owner Ted Leonsis praised the documentary and called Gartner “a true role model, not just for players but for anyone who values loyalty, perseverance, and professionalism.” Several former Capitals teammates, including Rod Langway, Dale Hunter, and Kevin Hatcher, have participated in the documentary, offering heartfelt anecdotes about Gartner’s leadership and his lasting impact on the team.
Another emotional element of The UnderDog will focus on Gartner’s relationships within the game. His friendship with fellow hockey icon Mark Messier and his mentorship of younger players, including a young Mats Sundin during his brief time in Toronto, are featured prominently. The documentary will also explore Gartner’s bittersweet departure from Washington, a city he called home for over a decade, and the complicated emotions behind his many trades late in his career.
Longtime Capitals fans will be thrilled to hear that the film contains deep dives into some of Gartner’s most memorable moments in D.C., including his legendary four-goal game against the Philadelphia Flyers and his remarkable 500th career goal celebration at the Capital Centre. Archival footage shows the roaring crowds, the iconic red, white, and blue uniforms, and Gartner’s signature understated goal celebrations — a nod to his humble demeanor.
Perhaps one of the most anticipated segments will be the detailed recounting of Gartner’s Olympic experience. Though he never captured a Stanley Cup, Gartner did represent Canada proudly at international competitions, including the 1984 Canada Cup. The documentary highlights the pride he felt wearing the maple leaf and the respect he earned from teammates and rivals alike.
Critics and insiders who have seen early cuts of The UnderDog are already hailing it as a masterful portrayal of an often-overlooked giant of the game. “It’s one of the best hockey documentaries I’ve ever seen,” said veteran NHL broadcaster Doc Emrick. “It’s not flashy. It’s not sensationalized. It’s simply a beautiful, honest tribute to a truly great man.”
Netflix has announced that in addition to streaming worldwide on its platform, The UnderDog will have a limited theatrical release in select cities including Washington, New York, and Toronto — three markets where Gartner made his biggest professional impacts. Special premiere events are being planned in Washington, D.C., where Gartner is expected to attend alongside Capitals legends and local dignitaries.
To build anticipation, Netflix has already dropped a teaser trailer that has generated a buzz among hockey fans online. The short clip features haunting slow-motion footage of Gartner skating in a Capitals uniform, a stirring piano soundtrack, and Gartner’s voiceover saying simply:
“Sometimes, the ones who don’t make the most noise leave the deepest echoes.”
The full trailer is set to debut during Game 1 of the 2025 Stanley Cup Finals, ensuring massive exposure for what is already shaping up to be a must-watch for sports enthusiasts, history buffs, and documentary lovers alike.
As the hockey world eagerly counts down the days to October 15, 2025, The UnderDog stands ready to remind us all that greatness is not always measured in rings or trophies. Sometimes, it’s found in the steady, quiet excellence of a man like Mike Gartner — a true underdog whose legacy will now be immortalized for future generations.
