Now, one of my close friends dropped a surprise choice on me when I asked him the same movie question I asked the X users. He shared my love of the final movie on this list, but also included: "Stalag 17."

Stalag 17 (1953), as many readers might know, recounts the exploits of American soldiers being held in a German prisoner of war (POW) camp during World War II, and stars William Holden, Don Taylor, Robert Strauss, Harvey Lembeck, Peter Graves, Neville Brand, Richard Erdman, Sig Ruman, and Otto Preminger. //
Men of Honor (2000) is a great low-key choice //
Another title that surfaced was Hacksaw Ridge (2016), a more recent war offering starring Andrew Garfield, from director Mel Gibson. //
The William Wyler-helmed The Best Years of Our Lives (1946) focuses on vets and their loved ones readjusting (or failing to readjust) to civilian life after World War II. It's amazing to me how the movie was made just a year after the war ended.
