Frankenstein Meets the Wolf Man is the fifth film in Universal Pictures' Frankenstein franchise, as well as the sequel to 1941's The Wolf Man. The film is notable for being Universal's first attempt at making a crossover, in addition to introducing the iconic "Frankenstein Walk". However most people do not know the reason for this installment's odd portrayal of Frankenstein's Monster, said reason being that he originally had spoken dialogue, all of which was deleted from the film.
Legendary horror film actor Bela Lugosi had previously portrayed Ygor in 1939's Son of Frankenstein and 1942's Ghost of Frankenstein. He had also been cast as the Monster in the first movie and later backed out. Regretting his decision, Lugosi was glad to be playing the Monster in this film. However, at the climax of Ghost of Frankenstein, Ygor gets his brain transplanted in the Monster's body and ends up losing his eyesight. This would cause a change in the next film.
The dialogue for the Monster in the film would be different than the previous lines from the previous four films. Reportedly the Monster would have a split personality switching from the Monster and Ygor. Lines included "Frankenstein gave me life and his son gave me a brain". The dialogue was a big part of the story explaining that the Monster was blind which, when cut, ended up creating the "Frankenstein Walk".
After the film was completed, test audiences found the Monster speaking with Lugosi's natural Hungarian accent unintentionally funny. This is what is generally assumed to be the reason that Lugosi's lines were cut, causing a few inconsistencies such as when the Monster is brought to "full power", as his eyes flutter open and he can be seen smiling (this was meant to signify that he had regained his sight and strength, the blindness as well as the weakness which was to be explained previously). The dialogue has since been lost and there is a possibility that the audio may have been destroyed by Universal.
Some years ago, YouTuber Cynthia Levin, after removing some background music, found that a small snippet of Lugosi's dialogue was somehow left in, which cannot be heard during normal viewings of Frankenstein Meets the Wolf Man. The line in question is: "It's all here!".
