Harrison Ford’s experience on the set of Force 10 from Navarone (1978) was largely negative and unfulfilling. This was his first major film after Star Wars (1977) made him a star. He played Lieutenant Colonel Mike Barnsby, leader of an American commando unit in this loose World War II sequel to The Guns of Navarone. Ford took the role primarily for the money and to avoid typecasting as a sci-fi hero (like Han Solo), seeking a different “macho tough guy” part. By almost all accounts, including his own, the shoot was a grueling, frustrating experience.
Directed by Guy Hamilton (famous for Goldfinger), the World War II action film was shot on location in what was then Yugoslavia (specifically parts of Montenegro and Bosnia and Herzegovina). Production took place during a harsh, freezing winter. The cast and crew faced bitter cold, deep mud, and frequent logistical delays in remote mountainous regions.
Ford was incredibly frustrated by the constant script rewrites. He later admitted that he accepted the role of Lt. Col. Mike Barnsby largely because he needed a job and wanted to see if his Star Wars fame was a fluke, but arrived on set to find a screenplay that wasn't ready. He spent a significant amount of energy trying to make his character’s dialogue and motivations make sense on the fly.
Ford has been famously candid about his dissatisfaction with his own performance and the movie as a whole. Decades later, he reflected on the shoot with his trademark bluntness: “It wasn’t a bad film. There were honest people involved making an honest effort. But I didn’t know what I was doing. I was a leading man, but there was nothing for me to lead. There was no character to play. I just had to try and project a strength that I didn’t feel.” He felt the film relied too heavily on spectacle and action set-pieces, like the climactic destruction of the Đurđevića Tara Bridge, rather than strong character development.
Despite the difficult shoot, Ford bonded with his co-stars. He shared the screen with Robert Shaw, Edward Fox, and Carl Weathers. Because Shaw was notoriously competitive and Fox brought a highly disciplined, classical British acting style to the set, Ford had to carve out his own space as the rugged, understated American counterweight.
While the movie ultimately underperformed at the box office and was panned by critics, it served as a massive learning experience for Ford. It taught him how to navigate chaotic, big-budget studio sets, a skill that would serve him perfectly just a few years later when he teamed up with Steven Spielberg for Raiders of the Lost Ark (1981).
