Writer Wayne Warga reported in the April 14, 1974, Los Angeles Times:
The castle looms dark and foreboding, a dead tree in a courtyard leading to outside doors with huge knockers. The kind of place where people must come to die. Frankenstein's place. And this time the devout wish is that we'll all die laughing. It's Mel Brooks' version of Frankenstein's place.
It's impossible to tell how many versions of this classic tale have been made around the world, but certainly this must be the first one in which the monster has a zipper in his neck.
The $350,000 castle, on Stage 4 at 20th Century-Fox, is an inspiration of the macabre, while the goings-on of its inhabitants are inspiringly silly.
Brooks is shooting the film in black and white and is using cinematic techniques prominent in the late 1920s and the early 1930s. "It's not satire, it's a salute," he says. "It says, 'Mel Brooks Presents Young Frankenstein' so the audience will, of course, know the comedy will go an inch or two further than one usually expects. But you can't keep winking because it diminishes the melodrama. The melodrama has to be there."
Brooks at work is intense, serious and determined — in startling contrast to the inspired silliness of his films. Gene Wilder plays Frankenstein and, along with Brooks, is the co-author of the screenplay.
"Gene walked in one day and said he wanted to do a picture called 'Young Frankenstein,' Brooks recalls. "I told him he was crazy. A week later we were writing it." …
"Young Frankenstein" became a smash hit. It’s now highly ranked on many best comedy film lists.
