Cool Hand Luke (1967)

Continuity mistake: In the scene where Coco tears up the photo of Luke with the women, he tears it carelessly, starting with the upper left corner. The end shot of the movie shows the same photo, reassembled, showing a neat, cross-wise tear, with the center of the tear directly over Luke's heart.

Captain: What we've got here is failure to communicate.

Trivia: When Luke escapes for the first time, he is being chased by a loose dog dragging a leash. Luke jumps over all kinds of obstacles to make it tougher for the dog chasing him. Finally, Luke dives off a bridge into a stream. In the theatrical version, the dog also jumps off the bridge, but the leash gets caught on the bridge and the dog gets hung.Quite a shocking sight. In the videotape and other releases, the dog boss (Anthony Zerbe) claims the dog died from exhaustion, you never see the dog get hung.

Question: Why did the new convicts arrive at the prison wearing prison pants but civilian shirts?
