Continuity mistake: When the Privates are having their furloughs authorised, Colonel Sangston walks in with Corporal Cannon. Only those two men walk in. Corporal Cannon moves from the doorway to give Desmond Doss his rifle leaving no-one by the doorway. After Desmond refuses to touch the rifle, the Colonel shouts at Desmond. Out of nowhere Captain Glover mysteriously appears in the doorway. (00:48:40 - 00:50:10)
Continuity mistake: When Sook-Hee is standing outside in the rain before leaving, she is shown holding an umbrella whilst it rains. She walks over to say goodbye, whilst still holding onto it. A second later, she leans in to kiss a baby on the head, and the umbrella is no longer there. It is shown later that she placed the umbrella on the ground, but she was not shown doing this earlier in the scene. It just disappears in between shots. (00:02:20)
