When typing in the first breakfast order into the machine, Flint orders the eggs "over easy", but when it rains, the eggs that are falling are "sunny side up".
When the giant fish bowl breaks loose, the spectator from the 'Splash Zone' can be seen leading those fleeing, but in the next shot is back in his seat being missed by the splash.
The "spaghetti tornado" originally rotates clockwise, then counter-clockwise, then back to clockwise.
The GUI of the computer in Flint Lockwood's lab changes from either a Unix or Windows interface, with restore, minimize and close icons on the windows on the right initially. However, when his dad sends the email, the GUI is a representation of a Mac OS with the icons on the left and in standard Mac OS colors.
When Flint and Tim Lockwood are at The Roofless and Flint climbs on top of the table, Tim only has a small plate in front of him. After Flint sits back down, Tim suddenly now has a large plate, which is then broken by the giant steak.
The dam that prevents the leftovers to flood the city with uneaten food is arched the other way around. An arch dam built that way would collapse instantly as soon as any load is applied.
The FLDSMDFR breaks the water molecules to hydrogen and oxygen, and recombines them to create bacon. However, food consists mainly of carbon, which can be derived from water only by nuclear fusion, and it can't be done by the machine microwave energy.
The radar screen on the portable Doppler radar sweeps counterclockwise. It should be clockwise.
If looked at closely, the dosage of the epinephrine auto-injector is 0.15mg. This is the dosage of the drug for patients weighing 33-66 lbs. These injectors are often labeled "junior". Since Sam weighs over 66 lbs, she would need 0.3mg to be revived by the injection.
When the screen cuts away to the Cities Weather Forecast, several cities listed have anomalous weather readings. Some have extremely cold weather with a rain cloud next to them (if it were that cold, any precipitation would be snow), and some have mild temperatures with snowflakes next to them.
When Sam Sparks returns to broadcast the weather in Swallow Falls, she has a microphone. She previously threw her old microphone into the Atlantic Ocean. However, it is possible that Manny gave her one if he had extra microphones in the news van.
The mayor asks for a major network's professional reporter that has the most experience to report on the unveiling. Sam Sparks is an intern who is on her first day, and she has very little experience given these circumstances.
However, that is literally the joke, that the mayor wants a professional reporter and gets sent an intern who is just a "TV weatherperson".

Patrick remarks to Sam that he has not seen a scrunchy since 1995. Scrunchies were actually very popular in the late 1990s.
However, Patrick is stating he has not seen a scrunchy since 1995, not that scrunchies may or may not have been popular in the latest 1990s.

When the FLDSMDFR lists foods while it is floating in the sky covered with food, the foods are said with different frequencies. However, this makes sense because the machine is in the red zone in the Dangeometer and is therefore malfunctioning.
When the Mayor is leaning against the fence, his left thumb passes through the fence geometry.
In the Netflix print during the end credits, there is some animation without text. Since no voice acting credits are shown during the rest of the end credits, they clearly were forgotten to get implemented during that bit.
When the FLDSMDFR shoots a giant corn at Flint, he suddenly disappears right before it hits him as he dodges it.
When Steve is throwing chocolate snowballs, he is making monkey sounds, despite having the Monkey Thought Translator attached to him.
The line "That's a really weird dude" is spoken by one person, but two people are seen moving their lips when the line is said.
When Flint is giving Sam a tour of the Jello structure he has made for her, he tells her that "everything is made of Jello" while he is playing the piano. A piano made with "Jello strings" would not make any noise.
When Tim Lockwood has the Monkey Thought Translator on, most of his speech sounds like it came from a recording. When he states "I love my son", it is his actual voice instead of the recording.
When the clouds are seen approaching Manhattan, the city can be seen. The Empire State Building is located in Upper Manhattan, but yet is portrayed as being in Lower Manhattan, almost near what was then Ground Zero.
When Sam explains the Coriolis acceleration rate of the storm system, she states that the storm will hit the Jiayuguan Pass in eastern China. However, the location that is shown is England, not eastern China.
Nearing the halfway mark, when Sam is giving the Food-Weather report and they show Times Square in Manhattan, it is jammed with cars, and every single vehicle is a cab. Manhattan has a lot of traffic, and a lot of yellow cabs, but not every car is a yellow cab. Also, the cars are shown facing in opposite directions, but at that point, with the camera facing north, all cars would be facing the camera (south), since Seventh Avenue is a downtown-only avenue. Furthermore, Broadway crosses Seventh Avenue at the point of the central building, going east, so all the traffic would not be parallel, as depicted. Finally, there are ten lanes of traffic shown; nowhere in New York, not even on any highway, are there ten lanes of traffic.
The FLDSMDFR needs a power station to enable it to work. The film never explains who or what powers it when it is floating in the sky.
No other character besides Cal is seen getting sick from the larger portion sizes.
Brent does not get arrested by Earl for indecent exposure at neither the Sardine Land unveiling, nor at the town's reopening event, despite being told to put his clothes back on at that event.
Flint asks Brent to return Sam to the plane so that she can have an allergy shot. Allergy shots are treatments to stop or lessen allergy symptoms. Sam was having an allergic reaction.
While running with the scissors, Brent is holding them in the wrong direction. The sharp end of the scissors should be facing downward.
While the Mayor throws a beet at Flint in an attempt to destroy his lab, Flint yells "That's a radish!" Radishes are from the mustard family, while beets are from the Conditiva group.
Since Manny is a doctor, he should have taken Sam to a hospital and have her stay there for four to six hours after being injected with epinephrine after touching one of the peanut brittle spikes.
