Factual error: Peter Townsend is depicted in 1945 wearing the ribbons of the DSO (which he won in 1941) and the DFC (which he won in 1940), but not the rosette indicating a bar to the DFC (which he also won in 1940) and the 1939-45 Star (which he would have been awarded in 1943).

Continuity mistake: As Philip paints his parrot, its head can be seen half-painted. When Parker enters the room and the camera switches focus to him, the head can be seen in the background fully-painted. However, when the camera returns to Philip, the parrot's head is again only half-painted. (00:24:42)
