In all of the newspaper headlines, and in the warden's list of death row inmates, Tommy's surname is spelled "Gordan," and Mike's surname is spelled "Kagel," but in the cast credits, they are spelled "Gordon" and "Cagle," Tommy's as it also is on the telegram the Warden passes along to Tommy.
At the beginning, as the three men run out of the novelty shop, one jumps into the front seat and two into the back. Only moments later, Tommy Gordan is in the front passenger seat.
When the bomb goes off in the store, the front window is completely blown out, but the two chairs in front of the window do not even move.
By freezing the frame, it can be seen that the one of the men in the shower with Tommy is wearing swim trunks while showering with the other inmates.
As the train pulls into station, the conductor announces "Ossining." A sign can be seen through the window---"Lord and Burnham, Irvington, New York." Irvington is four stations south of the Ossining station.
