Continuity mistake: When Susannah finds Tristan crying at Samuel's grave she takes him into her arms and consoles him. This is seen from different angles, with Tristan's hair behind his ear or not, and in one strange brief shot with a straight, expressionless face, very different from all others where he is sobbing hard and his face is twisted with grief.

Continuity mistake: When Tristan and Samuel hug in the trenches in the war, at first Tristan's chin is on top of Samuel's hat, but when it cuts to the other angle, their heads are level, side by side. (00:36:00)
Continuity mistake: In the scene of Alfred and Tristan at Susanna's grave, when shots of Alfred show him speaking to Tristan, he looks to his right, as if the two men were side by side and facing the grave, and they seem to have been side by side in the last shot in that scene, when they leave the grave-site. However, the sun lights the left side of Alfred's face, and in the alternating shots, which show Tristan listening to Alfred, the sunlight is on the right side of Tristan's face.
