When Rose, Baby June, Louise, and their grandfather enter the grandfather's house in Seattle, the number on the front of the house reads "3801." In the very next shot, when Herbie is filling out a telegram to Rose (who is still staying at the grandfather's house), the address on the telegram is "733."
During 'Rose's Turn', after Rose sings, "Mamma's letting go," she puts her hands in front of her abdomen, then in the next shot, her hands are down.
Towards the end of the movie, before the men enter Gypsy's dressing room, she is standing in front of a mirror. When she greets the men, there is suddenly a red ribbon around her hair.
When they get out of car at their grandfather's house June and Louise are carrying suitcases with right hands, but seconds later are carrying it with their left in reverse shot.
When Rose starts to sing 'Some People', her red bracelet is up towards her right elbow. In the verse, "when I got all the sights to see yet, all the places I gotta play..." she puts her right hand up, the bracelet is back down at her wrist, although we don't see it slide down again in between the shots.
In the first half of the film all of Rose's vaudeville show is crammed into one touring car. Yet during the audition for Mr. Granzinger there are ten grown performers on stage with complete costume changes, massive stage backdrops, sets, and 12ft moving props.
When Herbie tries to sell the theater owner an order of Butterfingers, he tells the man he's going to put him down for 100 gross. That would amount to 14,400 candy bars. He then promises the man they're so good he'll be reordering in a month.
When Louise comes out on the stage in Detroit, it shows the theatre audience from the stage and entrance to the theatre . When she comes out in Philadelphia in the next show, it is the same theatre as Detroit.
There is no Maple Street in Seattle.
During the birthday party scene, when the landlord comes in the shadow of a boom mike is visible on the wall.
Rose says Herbie, as Uncle Jocko, gets, "Six girls, semi-talented." However, there are definitely more than six girls who run out as the Toreadorables, and possibly two more as the Bull.
Throughout the film Rose gets upset at, and will not tolerate "dirty talk". Yet in the song "Some People" she accuses people of sitting on their "butts".
