Goofs

When Griffin first visits Kemp, he locks the library door and puts the key in his pocket, but when Kemp leaves, he easily opens the door, which is now unlocked.

The ink spots on the police inspector's face change between shots.

The man who has the bike torn from his hands was not present in the wide shot of the people scattering. Also, when the bike is torn away, the people who were running away have disappeared.

When Dr. Kemp stands before Dr. Griffin's opened cupboard, his cigarette jumps from his left hand to his right between camera cuts when Dr. Cranley walks away.

When Jenny enters the Invisible Man's room with the mustard, the way he holds the napkin to hide his lower face changes in between shots.

Unfortunately a truly invisible man would also be a blind one. An invisible cornea would not refract light and an invisible retina would not register photon impulses.

Whiskey and Rye are for sale in the supposedly British pub. Whisky would be spelled without an "e" and Rye wouldn't be for sale at all. However, in places other than Scotland, whiskey IS spelled with an "e".

The pub is in Iping, England, and it actually has both whiskey and whisky (in a large glass urn to the left of the rye barrel), as well as rye. Canadian Rye Whisky (which is not required to have any rye in it) was being exported to England by the early 19th century.

With all the spare time Kemp had while he was giving the Invisible Man his clothes, he could have locked all the doors and called the police. [Of course, not all doors have locks, and there almost always are windows.]

When the Invisible Man is in his pajamas and getting ready for bed, parts of his collar appear and disappear as his 'invisible' chin passes in front of it.

When the Invisible Man is riding away on the stolen bicycle, a practice mark and/or track can be clearly seen on the ground in front of the bike; the tires of the bicycle follow it perfectly.

Wires are frequently visible moving objects that are meant to be moved by the Invisible Man. This is most noticeable when he rides the stolen bike.

One of the tricks used to suggest Griffin's invisibility is the simple use of black cloth to hide Claude Rains' exposed flesh. This is particularly evident when Mrs. Hall barges in on the Invisible Man while he's eating. The black cloths covering the lower part of his face and his wrists as he holds the serviette up are clearly visible.

The men at the Lion's Head Inn are throwing darts from a 45º angle left of the dartboard, yet the darts in the board are from straight-on shots.

The streets of the town, obviously a studio set, do not look England in 1933. They look more like those of an eastern European town of a few centuries earlier.

Though the music at the pub comes from a coin-operated player piano, it, along with everyone talking in the pub, stops short at the startling arrival of the Invisible Man.

During the riot at the pub, a technician can be heard yelling, "Stay on camera!"

When the bicycle is "traveling", it is supported by two wires going through the handlebars. The man pulling it along can be seen in the distance as he runs off at 90 degrees to the direction of the cycle. The wire pulling it must go round a pulley hidden behind the cart. The puller must have started where he did, so he could see when to start running. His speed is exactly the same as that of the cycle.

The pub in Iping has an American-style dartboard instead of the more elaborate British-style dartboard.

A British Police station has the American words 'Police Department' spelled out on the door.

The story starts in a pub in the village of Iping, a real village in Sussex. The pub is full of people with a Cockney accent. This accent is peculiar to the East End of London and parts of the neighboring county, Essex. Sussex is south and west of London and more than 70 km away.

The film supposedly takes place in England; however, the train that gets wrecked has a distinctly American appearance.

Griffin says he must conceal himself for an hour after eating, as the undigested food is still visible. He also says he can be seen in a mist or fog. By that logic, the cigarette smoke in his lungs should be seen while he is smoking, but it is not visible.

Lloyds Bank has never had an apostrophe before the "s", but the town has a branch of Lloyd's Bank.

The Invisible Man, in London, says he wants to go back to the village of Iping, which is "only fifteen miles" away. Iping is, in fact, 45 miles from London.

A 'chief of police' is referred to. There is no such position in British policing.
