In 1974 there was no PG-13 rating, so PG was a more broader rating.  The laboratory props were from the original Frankenstein (1931).  They done a wonderful job, this is definitely a classic.

Marty Feldman (Igor) was goofing around, switching the hump from one side to the other, to see if anyone would notice.  When it was finally spotted, Mel Brooks decided to actually use it.

The lab equipment was the actual props from the original Frankenstein movie.

Mel Brooks provided the sound of the cat screaming.

One of the funniest damn movies ever made.  The sheer genius of Mel Brooks, Gene Wilder, Terri Garr, Madeleine Kahn, Gene Hackman, Peter Boyle, Cloris Leachman and Marty Feldman is everything. What a cast. 😁❤️

The Blind hermit was played by Gene Hackman, and he improvised his last line about making Espresso, which broke up the crew so badly that the scene had to be cut that short before the sound of their laughing could be recorded, and he could only do it once.

Yes, Marty Feldman, who plays the peculiar- looking Igor ( Eye- gor!) had a thryoid disease which led to the protruding and misaligned eyes.

Yes Marty Feldman's eyes were actually like that due to a medical condition.

Gotta love Inspector Kemp; not a robot or cyborg, he just has a (jointed, hardwood) prosthetic arm after the original Frankenstein monster tore his old one off. He wears a monocle over an eyepatch, and cleans it on the brass buttons of his uniform. Kemp, the little girl, and the blind hermit are all inspired by characters from the first few Universal Frankenstein movies from the '30s and '40s. (There's also a comic relief character in Bride of Frankenstein who looks a bit like Frau Blucher.)

Fun Fact: all the electrical equipment in this Frankenstein's lab was actually used in the original 1930s film Frankenstein.

The blind man scene with Gene Hackman is one of my favorite parts of the film; I love the Monster gazing happily at his own blazing thumb, then "OWOOOW!!!

Another good film for Halloween is "Arsenic and Old Lace" with Cary Grant, Peter Lorre.  Adapted from a Broadway play of the same name. One actor in the play was Boris Karloff, who was not available for the film, and was replaced by Raymond Massey. But in the play and the movie, someone periodically would say "Look at him!  He looks like Boris Karloff!"

Puttin' on the Ritz is insane!
 "What hump?"

Great reaction guys,  keep in mind in 1974,  many of us had grown up watching the gothic horror films that were popular in the 30s and 40s, they were very scary and well done, so just seeing those characters in a comedic genre was different and funny to us.   I would put " The Exorcist"  and " The Shining"  on my list of scary movies to watch for this month.

Apparently Gene Wilder fought tooth and nail with Mel Brooks to keep the "putting on the Ritz" scene. After an hour of arguing, Mel said "fine, we'll keep it in". Gene was confused about the about face, and Mel explained that since Gene was willing to fight for it, he agreed to keep the scene in.

Also, the scene when Elizabeth arrives, Gene Wilder couldn't keep a straight face because of Marty Feldman's antics. In the shot they used, you can see Gene break character slightly when he said "stop that." But it was the best shot they had.

BTW, all the props for the laboratory from the original Frankenstein movie were  still available... stored in a warehouse and were used again in this movie

It is great that you guys are reacting to this one. A couple of things you should know about this one...first, it was Gene Wilder's script, his ideas and mostly his writing...he asked Mel Brooks to direct it for him, but set the condition that Mel was NOT allowed to play any role in it as an actor. Mel agreed, but he did make sure to get himself into the movie by voice acting a couple of sound effects...that was him that made that cat sound during the darts game that you commented on. The other thing to know is that the equipment in Frankenstein's laboratory is the same stuff that was used in the original 1935 Bride of Frankenstein movie...the electrician that had worked on the film had saved it all.
Sorry if anyone already told you these things. LOL ✌✌
I was wondering if you guys had noticed that the police inspector with the wooden arm...was wearing his monocle on his eyepatch...you did not comment on it, but you just may have left that part out of the final edit. 😂😂😂😂😂😂

The old man he hit in the nuts is in Blazing Saddles too. The preacher

You need to do the granddaddy of horror comedy films, ABBOTT AND COSTELLO MEETS FRANKENSTEIN. it’s still the standard of spoof horror films.

Marty Feldman (Eye-gore) had the disease called Graves' disease during his early childhood in which, after a botched surgical operation, his condition resulted in his eyes being more protruded and misaligned (strabismus).  He was discovered as an actor by a filmmaker who had the same condition.  What a great way to overcome a disability!!

A roll in the hay is an euphemism for sex. That's why Frankenstein had that expression

Transylvania is in Romania.  You can't really get there by train from New York City.  That Frau Blucher gag never gets old.
