The Odyssey's grueling production has left its mark on the cast, with Matt Damon revealing that half the cast, including industry heavyweights, ended up with back pain. The film's demanding physicality and authenticity, as well as the challenging production conditions, have taken a toll on the actors, who had to endure natural and man-made elements to create the epic journey of Odysseus. The film's lead, Matt Damon, discussed the physically brutal moments of filming, including running through the fictional version of Troy, which was a particularly unpleasant experience due to the stone terrain and the strain on their back. The production's demanding nature is reflected in the cast's exhaustion, with Robert Pattinson describing the experience as a third of the way through the shoot, and Tom Holland feeling like he was in a reenactment rather than a film set. The film's larger-than-life experience and the nostalgia for the early days of the movie business have left a lasting impression on the cast, with Matt Damon expressing a sense of uncertainty about ever being able to live through such an experience again.
