At the end of the film, Joan Sims as new head of the gang, plans to rob a train from Edinburgh with used bank notes worth five millions pounds. This film was made two years after the Great train robbery however that train was from Glasgow and was carrying 2.6 million pounds in used bank notes. Joan also mentions changing the signal to red which occurred during the Great train robbery. Also Sid James character's name is Brain, hence the Great Brain robbery. These are all obvious references to the Great train robbery.

The edges of the floor section that falls into the tunnel are visible prior to the floor's collapse.

In a scene where the robbers are climbing into the police station back yard, the ladder they are using does not reach the top of the wall. However, when they drop down on the other side, the top of the ladder is at least 2 feet above the wall. Similarly when George first spies the ladder against the girl's window, it reaches above the window ledge, but when the young man climbs it when the couple are eloping, it does not reach to the window.

The wire to pull the harpoon out of the harpoon-gun can be clearly seen in the shot just before the first one is fired into the tree.
