Continuity mistake: During a lesson on brains, there are two jars with type-written labels ('Cerebrum - Normal Brain' and 'Disfunctio Cerebri - Abnormal). But when Fritz approaches the containers to steal the brain, the labels (Normal and Abnormal) are handwritten. (00:07:15 - 00:08:45)
Continuity mistake: When Fritz is trying to steal a brain, he gets scared by a skeleton, which he grabs down, causing it to bounce up and down (since it is hanging from a hook up on the ceiling). But in the next shot, the skeleton is hardly moving. Yet when Fritz realizes he has dropped the brain, the skeleton is bouncing up and down again. (00:08:40)
Continuity mistake: Just before Victor enters Elizabeth's room, there is a shot of a picture of Henry Frankenstein, which is at the same height as a lit candle. But in the next shot, when Victor and Elizabeth walk by the table (the one on the far right of the screen) where the picture stands, the candle now appears to be much higher than the picture.

Visible crew/equipment: When Dr Frankenstein asks to the monster to enter the room so that Dr Waldman can see him, you can see the shadow of the crew moving on a pillar as the camera follows them. (00:31:20)
Continuity mistake: After the experiment with the light, the Monster sits down on a chair, waving his hands as if he was asking for more. But in the next shot, the Monster is as still as a statue. (00:33:30)
Revealing mistake: When Dr. Waldman gives the monster an injection and the Monster is trying to get the torch out of Henry Frankenstein's hands, if you look closely, Boris Karloff's (the Monster) make-up begins to smoke when he is hit by the torch. (00:37:35)

Answer: By the third film, the original "Baron Frankenstein," played by Frederick Kerr is supposed to have died. Therefore, his son Henry had inherited the title of "Baron Frankenstein," and as part of Germanic aristocratic inheritance this automatically places a "von" between the Christian name and Surname of the holder. This in turn has happened when Henry died and Wolf took up the Baronetcy.
