Goofs

Bela the Gypsy transforms into an actual wolf, not a wolf/man. When his body is discovered, his feet are bare but he is wearing a shirt and trousers. The wolf killed by Larry Talbot was not wearing any clothing.

When Maleva, the Gypsy woman, asks to see Larry Talbot's wound from the wolf bite, he unbuttons and spreads his shirt front (with his bared chest outside the camera's view). Talbot then proceeds directly home where he begins to change clothes. He removes his shirt to reveal that he is wearing a tank-style undershirt underneath.

During the climactic scenes in the forest, the same log (resembling an open alligator's mouth) is seen in different sections of the forest at the same time.

Talbot refers to Captain Montford at least twice during the film, while the credits show him as Colonel Montford.

At Larry's home, the butler opens the door and Larry stumbles in his arms, while Gwen and the gypsy are behind him. It jumps back to the butler just opening the door to reveal Gwen holding Larry's right arm, and the butler taking his left arm.

When Larry looks through the telescope at the beginning, the image is shown is right-side up. Astronomical telescopes turn the image upside-down. While they can be fitted with a special prism to turn the image right-side up, they usually are not since usually there is no practical reason to do so.

Although the Talbot Castle attic is said to have been converted into a celestial observatory, the huge astronomical telescope is mounted on a fixed-floor mount beneath the attic ceiling, with only windows in the walls to look through - laterally, not vertically.

A graveyard that is still in use would not have trees growing throughout it.

The Village buildings are more typical of a central European village than an English one.

From Larry's bedroom window, the Talbot Castle is surrounded by a woodland of straggly trees. In reality, it would be surrounded by a well-kept lawn.

When Larry starts to transform for the first time, he has removed his medium-shade suit jacket, tie, shirt, shoes and socks, leaving him in an undershirt and the suit's trousers. After his transformation into the Wolf Man, he is wearing a dark, long-sleeved shirt and matching trousers.

However, when he regains his normal form with no memory of what has happened, Larry notices his different clothes, although this mysterious change is almost immediately forgotten and never explained.

Bela transforms into a dog-like wolf, but Larry transforms into a man-like one. Having been bitten by one type of werewolf, Larry ought to transform into one of the same kind.

However, the lycanthropic condition is paranormal, and there is no evidence to suggest in what way it would affect different individuals. The same diseases manifest themselves differently in different people, so there is no reason to suppose lycanthropy would cause a uniform change in its victims.

Although all of the characters are British, most of the main actors have American accents.

When Larry Talbot sits on the chair in his room and first changes into the Wolf Man, only his feet can be seen to change. However, when the Wolf Man stands up, the pant legs ride up from his furry Wolf Man feet and bare skin on his legs can be seen above the top of the "Wolf Man feet" boots he is wearing.

When the Wolf Man is caught in a trap and falls over a log, the arm of his shirt raises, revealing a gloved hand.

At the beginning, Larry Talbot is riding in a convertible with the top down. The car appears to be moving at around forty to fifty miles per hour, which would provide quite a bit of wind. Yet, Larry's hat is not blown off his head, which sits directly above the windshield.

After Larry Talbot has been bitten a long shot shows the Talbot family butler open the living room door to let Larry stumble in. It then cuts to a closeup that repeats the action exactly, including the butler opening the door.

When the gypsy woman, Maleva, reaches out with one hand to lift the lid of Bela's casket, it is obviously not being lifted by her fingertips, but by an unseen crewman on the off-camera end of the lid.

When Larry Talbot, the Wolf Man who can tear out throats with super strength gets caught in a steel trap, he is unable to free himself. If the trap was silver, it might hold him.

Although Larry Talbot (Lon Chaney Jr.) consistently addresses Sir John Talbot (Claude Rains) as "Father", Chaney slips when he asks "Do you believe me, John?" in the castle parlour before they go together to the church service.

Larry Talbot says, "Bela the Gypsy was a werewolf. I was bitten, look -- the Pentagram." (He shows him a star-shaped mark.) Sir John Talbot replies, "That scar could be made by most any animal." NOTE: Animals leave claw-shaped marks or fang-shaped marks. There is no animal that leaves a star-shaped mark.

Larry's father remarks that he has arisen early. Not 5 minutes later, he admonishes him to hurry, or they will be late for church.
