When Ossie Davis strips to his shorts, the style of shorts changes from the time he leaves the cell block to the time he gets to the commandant's office.
Late in the movie, RSM Wilson circles the broken Tpr Roberts delivering a motivational barracking, the camera following Wilson through 360 degrees.
The sequence is preceded by a long shot of Wilson and Roberts surrounded by ten yards of empty desert.
As Wilson utters the words "You'll double, drill, do anything...", the camera pan reveals Sgt Williams standing a yard or two away, and Sgt Harris alone at the medical hut doorway in the distance.
After dealing with Roberts, Wilson turns to face the medical hut doorway, where Williams and Harris are standing side by side.
Wilson then summons Williams, who trots over to assume the position he was just seen in.

When the prison is standing formation before inspection the wind has the flag standing straight out. But as the camera moves to the from of the formation and goes to a shot looking straight up the flag pole, the flag is becalmed and hanging straight down. That shot lasts for about seconds and then the scene returns to the long showing the flag briskly blowing in the wind.
When Staff Sgt. Williams "introduces" the five prisoners to the hill, he refers to the "north face" but from the shadows, it's clear that it's really the south face.
The steel, stone, and dirt construction of the hill belies its authenticity by the finished appearance on screen. Had it been real, the slope of the outside stone embankments would have been much more gradual, and much wider, like pyramids. Stone walls as steep and shallow as portrayed in the film would have quickly collapsed.
Ossie Davis speaks with a West Indian accent, but when he is talking to the Commandant about Stevens' murder, his accent is gone.
The first time the new arrivals are shown around "the hill" by Staff Williams, the shadow of the rig is clearly visible as the camera performs a 360 degree shot from the top of the hill.
The new prisoners are lined up in the middle of the camp with their kit at their feet waiting to see the army doctor. As Stevens is called, a flat board suddenly appears in front of the line up so the camera can pull forward along the line up for a tracking shot. It disappears immediately afterwards.
When the five new prisoners are ordered to empty their kits, a camera shadow is clearly visible passing over them on the left edge of the screen.
As Wilson confronts Roberts and King (at about the 90-minute mark), a camera shadow passes over a guard's back.
When fat Bartlett (Roy Kinnear) is trying to climb the rope, Stevens (Alfred Lynch), who is supposed to be despondent and exhausted, can be seen in line suppressing a broad, amused smile.
When departing-prisoners Walters and Martin are being "doubled" to the RSM for his exit remarks, they begin marking time in-place a half-second before they are ordered to do so by the staff sergeant.
