While eating at the hamburger place, the cigarette in Brookman's left hand changes into a napkin between shots.
At the end, the beer mugs fill themselves.
Pola picks up a fur wrap from the bed at the wedding party and drops on the floor. While she and Schatzie are talking, the wrap is back on the bed.
The flowers change position in the bedroom during the wedding party.
One of the motorcycles that stops Loco and Brewster on the bridge changes its design from when it is seen starting up to when it pulls over the car.
Benton insinuates that the Europe-bound Freddie is a tax cheat. In real life, the IRS would have had Freddie's passport revoked.
Loco tells Eben and Brewster that she and her mother attended the 1952 Elks convention in Philadelphia. The 1952 Elks convention was held in New York City.
Loco tells Eben and Brewster that she and her mother attended the 1952 Elks convention. Only the wives of delegates could attend the conventions. The Grand Lodge admitted women in their own right in 1995 after the Elks Lodges of Utah voted to become unisex in 1993 to avoid not losing their liquor licenses by violating the state's Civil Rights Act by not admitting women.
Lauren Bacall is shown with a cigarette holder in the movie's poster, yet she never uses a cigarette holder in the movie itself. However, as movie posters, closed captioning, and other such items are not part of the movie itself, per the IMDB style guide, this is NOT a Goof.
Pola winds up on the wrong plane because she confuses "Kansas City" with "Atlantic City". Yet the two names sound so dissimilar, it's a stretch to believe she got them mixed up. However, this is just another joke about her eyes.
When Brookman first telephones, he tells Schatze he didn't realize who she was until he saw her in a magazine as "Miss Steinbach Beer", yet that doesn't explain how he got her number. While it's reasonable he contacted Steinbach Beer or her modeling agency, nether would have given him her number without her permission. However, money talks and we learn later that he has plenty of it.
Schatze tells Loco that Hanley is worth 30 million, then tells Pola minutes later that he's worth 50 million. However, both times she's just embellishing.
Eben tells Loco that his family has a place at Dexter Mills. There is a Dexter, Maine, but not a Dexter Mills, Maine. However, as this movie is not a documentary but a fictional story, the names of towns do not have to reflect actual locations.
When driving back from the lodge on a twisting road, Brewster's steering motions don't match the view from the rear window.
It's raining when Freddie is on the terrace. When he slides open the glass-paned wall to enter the apartment, his hand goes through a pane, revealing there is actually no glass.
As the car drives past on the snowy highway en route to the lodge in Maine, it can be seen that the snow has been removed to facilitate the setting up the camera equipment off to the side of the road.
When Schatze is walking up and down on the roof, her shadow isn't matching the shadows on the buildings behind; her shadow falls the opposite way due to the lighting not matching the supposed position of the sun.
Pola repeatedly demonstrates that she is completely blind without her glasses, yet she answers the door for Loco and Hanley, then finds the door handle of the ladies' room the first time after bumping into the wall, despite not wearing her glasses either time.
Pola tells Schatze that the other models call Loco "Loco" for "crazy", yet Loco hardly lives up to her nickname.
When Schatze says to Hanley "... and who does he think he is anyway", the shadow of some lighting equipment can be seen on the painting near the mirror.
It's never explained how Hanley and Brookman know each other.
The lease is $1,000 a month, which Schatze tells Benton she wanted to discuss with Freddie. But since Freddie has left the country, Benton indicates the rent is lower as it'd be "the very height of folly" for Freddie to return. However, Schatze writes Benton a check without him telling her or her asking him how much the rent is now.
Schatze repeatedly pawns the furnishings to make the lease. She later tells Brookman that she'll be on the hook for the entire year unless Loco and Pola return. Someone as calculating as Schatze would never have left herself so vulnerable to financial ruin, and she compounded the problem by not having Pola and Loco sign a sublease.
Benton admits he doesn't have the lease, but Schatze writes him a check then tells him to mail the lease to her. She should not have given him any money without reading then signing the lease, and he should have had all the necessary paperwork with him.
After stressing the need to "throw everything we make into the kitty", Schatze pawns the piano for $2,500, then says to Pola and Loco: "Well, kids, where will we eat tonight? The Stork or 21?".
Pola is supposed to fly to Atlantic City to meet Merrill, yet isn't the least bit upset when she learns that she took the wrong plane.
