Core Event
In preparation for Christopher Nolan’s upcoming three-hour epic “The Odyssey,” which opens in U.S. and Canadian theaters on July 17, 2026, 55-year-old actor Matt Damon adopted a “complete lifestyle change.” He eliminated gluten, trimmed his weight from a typical 185–200 lb range to 167 lb—the lightest he’s been since high school—and followed a rigorous training program with a personal trainer. Damon described the shift as “getting jacked in your 50s” and said the diet “completely changed my life” over the past two years.
Background & Context
Nolan insisted on practical effects and real-world scale, shooting in six countries (Morocco, Greece, Iceland, Italy, Scotland, Western Sahara) with IMAX cameras and minimal CGI. Cast members endured extreme weather on open-sea ships and in remote caves, prompting the crew’s inside joke “the ‘Odyssey Five’” for nights with only five hours of sleep. Damon’s transformation echoes a previous 1996 weight loss for *Courage Under Fire*, which a doctor warned could have “shrunk my heart permanently.”
Data & Statistics
- Weight before filming: 185–200 lb (average)
- Weight during filming: 167 lb
- Film budget: $250 million
- Opening-weekend forecast (U.S./Canada): $80 million–$100 million
- IMAX cameras: first feature shot entirely with this format
Official Statements & Responses
Director Christopher Nolan said he wanted Damon “lean but strong,” emphasizing practical set pieces over digital shortcuts. Production staff highlighted the demanding schedule, noting that “it’s not an eight-hour-a-day job. It’s a 24-hour-a-day job.” Co-star Zendaya (Athena) called the viewing experience “visceral” and “speechless,” while Tom Holland (Telemachus) praised the story’s contemporary relevance. Universal Pictures promoted the film as Nolan’s most challenging project to date.
Criticism & Opposition
No dissenting commentary or criticism regarding Damon’s diet or training was reported in the available sources.
