Continuity mistake: When the townspeople are saying their goodbyes to Sheriff Bart, Mongo clobbers a man wearing a derby next to him and the man falls to the ground. The next shot the crowd is still densely packed, but the man Mongo struck is not standing, on the ground, or anywhere to be seen - he has disappeared.
Continuity mistake: When the banner rolls up, it stops with about three inches of material hanging down. When Bart goes to pull the banner down, it's completely rolled up.
Revealing mistake: As Mongo enters the bar, you can tell the background is a piece of scenery just outside the entrance; there is a wrinkle in the fabric at the floor.
Revealing mistake: After Bart's announcement, the preacher holds up a bible. As he does, you can see that it doesn't move like a bible that size might. Plus, after the hole is "shot", the cover splinters from the pyrotechnic charge goes off, showing it's a wooden prop.
Other mistake: As Charlie and Bart are starting to get up from the quick sand, the light reflector is jostled, thereby causing the light to jump.
Continuity mistake: When the Sheriff comes into Lili's dressing room, she has her left hand resting on the desk.When she takes the rose you can tell her left arm is down to her side now. When she tells the sheriff to have a seat, she only raises her right arm but in the next shot her left arm is raised with her hand in the desk again.
Continuity mistake: When the two black workers are looking for quicksand, when Taggart and Lyle come into the scene, Charlie's hand is covered with sand, next shot as he moves around to Bart's side of the handcar it's perfectly clean.
Other mistake: When the Western fight breaks into the dance movie set, the background of the Western movie is seen, even though it was all several hundred feet away, on an outdoor set.
Suggested correction: This is entirely in keeping with the "reveal of the movie within a movie.
Of that, there's no question. I was pointing out that the sets for both movies were a distance apart...the Western backdrop should not have been seen.
Other mistake: When the gang rides into Rock Ridge, a cigar smoking man, standing in front of a door, takes a bullet through his hat, front to rear. There is no mark on the door behind him.
Audio problem: When Lili Von Shtupp is singing the "I'm Tired" song, an old, drunk cowboy stumbles onto the stage saying, "Oh my Miss Lili, oh my lovely angel, etc." but his lips are not moving at all. Right before she knees him in the groin, the overdubbed voice is still talking but the lips again aren't moving.
Continuity mistake: At the end of the movie, Harvey Korman gets pie on his face when he's behind the door in the men's room. He then has twice the amount of icing on his face as he is running across the street to hail a taxi.
Revealing mistake: Just before Mongo punches the horse, the rider's hands inch up on the rein. As Mongo swings, the rider jerks the rein, pulling the horse's head around as Mongo's fist approaches the horse's head.
Continuity mistake: In the fake Rock Ridge, Taggert kicks the doors of the Leather and Saddlery store, and it falls over. A moment later, the Leather and Saddlery storefront is back up and the doors explode.
Continuity mistake: As the taxi Hedley is in approaches Grauman's Chinese Theater, watch the movie title "Blazing Saddles" on the marquees. It moves slightly as the camera pans to keep the taxi in frame. Also, Hedley's suit and face are spotless, despite entering the taxi covered in whipped cream. And, it was afternoon when Lamarr got the cab, but dark at the theater. The studio and theater are only four miles apart.
Continuity mistake: After Mongo punches the horse and it's down, the snout is pointed toward the chest. In the close up, the head is at a more natural angle.
Revealing mistake: As Bart grabs the black king, watch his hands. He claps his hands around the king, draws the toward his body, and they dip partially down below the level of the table. When he does that, he opens his hands just enough to allow the piece to fall out of the camera's range. Then Jim pulls out a duplicate piece he had in his holster.
