Continuity mistake: Indians are on a hilltop and a jet vapour trail can be seen in the sky.
Continuity mistake: It is 1940. Two pilots come out of a house - one of them has just lost his wife and family in the London Blitz, the other is an RAF Squadron Leader. The door they come out of has a modern electric bell push - a post 1965 version, white rectangular box with a round button.
Continuity mistake: After the gang is pulled off the bank job, they race away in the three Minis - as they go through a tunnel at one point they roll up and down the sides of the tunnel. The mistake is that each car supposedly has two occupants, but on one shot of the cars in the tunnel, one car has only a single occupant - visible because the car following has his headlights on illuminating the car in front.
Continuity mistake: The chain gang truck is an International-Harvester when it first pulls to the side of the road. When the guards open the hood, the truck is a Chevrolet.
Continuity mistake: Gladstone has a drink in Dr Nookey's office, but he doesn't pour it. It just appears in his hand.
Continuity mistake: Frankenstein buys a sprig of freesias as a buttonhole: two yellow flowers and a purple. The sprig immediately changes into two purple flowers and a yellow. When Frankenstein meets Mrs Brandt and they go into the drawing room, the flowers are two purples and a red with yellow centre. Once in the cellar to see Mr Brandt, the red goes, and a yellow is back with two purples. (00:57:45 - 01:03:55)
Continuity mistake: At the end of the town collapse, a sincerely drunk Ben dives head-on into a tub where a lady (in her underclothes?) is just enjoying a bath. Propelled by Ben's momentum the tub with both passengers slides down the slippery planks and splashes into the river, while Ben rearranges himself into a comfortable sitting position between shots. If I wasn't completely mistaken also the lady changes her outfit, since the embroidery is missing when they float along. (02:23:35)
Continuity mistake: After crashing, the pilot jumps from his burning plane with the back of his jacket on fire. The flames are extinguished but after a short dialogue, the pilot is seen walking from the scene from behind with not even a scorch mark on his jacket.
Continuity mistake: On board ship in the captain's cabin, he is lying on a bunk. A shot from behind him, through a window shows his shirt or pyjamas to be undone showing bare chest, then the shot changes to in front of him and and the shirt/pyjamas are done up, showing no chest. We see this several times.
