Matt Damon Details 167-Pound Transformation for Nolan’s The Odyssey

The actor describes a strict, trainer-led regimen fueled by a gluten-free diet.

Overview

  • On the New Heights podcast, Damon said he filmed at 167 pounds after Christopher Nolan told him to be "lean but strong."
  • He noted he typically weighs 185 to 200 pounds and hadn’t been that light since high school.
  • Damon credited a trainer and a highly routinized approach, comparing the preparation to an NFL season.
  • He said he cut out gluten on his doctor’s advice during prep and has stayed gluten-free, joking about finding a gluten-free beer.
  • Universal released a teaser last month for the IMAX-shot adaptation, which features a large ensemble and is set to open July 17, 2026.
