Corrected entry: A painted dummy head fakes out the night guard inside Franks darkened cell, while Frank is up inside the vent system, confirming his escape route. The guard passes by Frank's cell twice, as after shots show Frank still toying around the escape shaft. Only a few moments later, the guard returns, suspicious, and remarks to Charlie Butts that Frank must be a very deep sleeper as the footsteps and noises have not awakened him. Then the guard clangs his nightstick on the bars to awaken Frank, but gets no response. He then grabs at the dummy's forehead and suddenly its a "sleeping" Frank - after only a split moment before where Frank was still shown in the vent system. Impossible time-frame sequence.
Corrected entry: When Charley Butts first gets to Alcatraz he is inside his cell and introduces himself to Frank Morris. According to the camera angle, Charley's cell is on the right and Frank's cell is on the left. Later on, it's like they switched cells. Frank's cell is to the right and Charley's cell is to the left. But later their cells are back in their original positions. Video only.
Corrected entry: After Wolf attacks Frank Morris and both are sent to D-Block, you will see the guards shove Wolf in one of the D-Block sells and then immediately slam the metal door shut. A few seconds later, the guards put Frank Morris in the adjacent D-Block cell, but before they shut the big metal door, they also slide a set of jail bars closed first. They didn't do this for Wolf.
