The shoulder patch that Cpl. King (George Segal) is wearing is that of the 34th Infantry Division (Red Bull). The 34th ID served in the European Theater of Operations, not in the Pacific. The 34th ID patch is a black Mexican water jug called an "olla" with a red bull's skull superimposed. Almost all the POWs at Changi were British or Commonwealth soldiers captured at the surrender of Singapore on Feb. 15, 1942, but there also were POWs from the Netherlands East Indies, which surrendered in March. The only sizable U.S. unit at Changi was Co. E, 2nd Btn, 131st Field Artillery Regt., part of the Army's 36th ID (the "Texas Division"). The Second Battalion, which became known as the Texas National Guard's "Lost Battalion," was detached from the 36th ID in the States and shipped to the Pacific in November 1941, but when the Japanese attacked the Philippines in December, the battalion's convoy was diverted from Manila to Brisbane, Australia. In January the battalion was sent to Java, in the Netherlands East Indies. The battalion was the only U.S. ground unit in Java when the NEI surrendered to the Japanese on March 9, 1942. Most men in the battalion were transferred to Singapore later that year and, along with thousands of British and Commonwealth soldiers, were used by the Japanese as slave labor to build the infamous "Death Railway" connecting Bangkok to Rangoon. Company E of the 2nd Battalion, separated from the rest of the unit on Java, was at Changi briefly in October-November 1942 before being sent to Japan as slave laborers. It would be plausible that Cpl. King was a member of 2nd Battalion, 131st Field Artillery, and that the movie's costumers got the wrong division patch for his uniform.

Just before the camp is liberated we can hear an airplane fly over and it is definitely a propeller operated plane; however, the scene displays a jet flying over complete with vapor trails. However, the B-29 Bomber is a 4 engined prop plane which flew high enough to leave substantial contrails (30,000ft+). Bombers normally flew in large formations but this is a single aircraft which may allude to the Enola Gay, which dropped the first Atomic bomb indicating that Japanese surrender imminent. However, the Enola Gay was accompanied by other B-29s on her atomic bomb raid.

At the end of the opening credits, a medic folds the arms of a newly-deceased prisoner and covers his face with his blanket. As the medic does so, the dead prisoner moves his own fingers as his hands are placed on his upper arms.

When Max lifts the pot of boiling water from the hot plate he lifts it from the bottom to pour with his bare hand, which he shouldn't be able to do if the pot is hot enough to boil water.

The British officers are shown wearing their rank insignia on their arms. The Japanese did not permit officers held as POWs to wear or show their rank insignia.

After Maj. McCoy and the others have been arrested for possessing a radio, and Col. Smedley-Taylor is waiting outside for news, the shadow of the boom mic being lowered is cast over the actors in the background.

King keeps his fresh eggs in an open bowl in a suitcase. They hide the case, before they can re-arrange the contents, in a hidden vault dropping it down sideways and undoubtedly breaking them. As they do this frequently they will have taken more care of this valuable commodity.
