(at around 1 min) Dr. Pym slams Mitchell Carson's face into the table, making his nose bleed from both nostrils. He holds a hankie to it, and in the next few cuts, there's no blood at all from that major face trauma. In a final cut there's a tiny amount of blood again.
(at around 1h 13 mins) When everyone is at Dr. Pym's house discussing the plan, Luis' shirt is unbuttoned in one shot but buttoned all the way up in all the other shots.
(at around 1h 35 mins) When Yellowjacket gets hit by Thomas The Tank Engine we see the train fully derail onto the table top from the perspective of Cassie Lang, however the very next shot is of Yellowjacket on the tracks, with Thomas' face directly behind him, so Yellowjacket can throw Thomas at Ant-Man.
(at around 1h 45 mins) When Scott, Paxton, Maggie and Cassie are having dinner together, the amount and position of the food on Cassie's plate changes several times throughout the scene.
(at around 7:20) When Kurt is shown in the introductory scene in Luis' apartment, he is wearing yellow-tinted glasses also seen later in the movie. Between cuts the glasses disappear, without showing or giving time for Kurt to remove them.
Several characters are supposedly bitten by bullet ants but carry on as if it had been regular ant bites without the debilitating pain. "The pain caused by this insect's sting is reported to be greater than that of any other insects and according to some victims, equal to being shot. It is described as causing "waves of burning, throbbing, all-consuming pain that continues unabated for up to 24 hours".
(at around 1h 30 mins) Flying ants could never get near a flying helicopter from below due to the prop wash of its main rotor.
Scott and Darren's voices remain the same when shrunk to insect size. Sound waves create a higher pitch when moved through a small area, and a deeper pitch in a larger area. The infamous "voice cracking" during puberty takes place because the throat is now larger. As frequently depicted in cartoons about shrinking, both characters should have high-pitched voices.
(at around 1h 26 mins) In the final fight scene involving Ant-Man, Hope, Darren Cross, and his henchmen in the laboratory, the ants can be seen holding back the hammer on the pistols that the henchman are using, stopping them from firing. The pistols they were in fact using were Glocks which are striker fired and do not have an external hammer. This concept is clever, and would have worked better if different pistols had been used.
Many of the ants in the film are referred to as male. In actual ant colonies, nearly all ants are female, and the males only live long enough to mate (similar to bees, wasps and other related insects). Thus, most if not all of the ants in the film should be female.
Ant-Man is repeatedly told that his mass does not change upon miniaturization. This means, however, that no ant or group thereof--crawling or flying--could support him. But the story also includes the ability to manipulate weight independently of mass and size.
(at around 1h 40 mins) Ant-Man shrinks smaller than atoms in one scene. If that were the case, he couldn't have been breathing as the oxygen molecules would have been too large. However, he spent too little time there to suffocate. Furthermore, any internal air supply the suit has would have shrunk with him. And given the drastically reduced lung capacity of a shrunken human, it is reasonable to assume that the suit has such an air supply as part of its normal functioning.
Most surfaces Ant-Man is seen on when he's shrunken (earth, concrete, wood, tin, glass) couldn't sustain a body 1/4 inch in size and 180 pounds in weight, without sustaining dents, cracks and holes. The pressure would be simply too big, especially when he starts running around. But the story also includes the ability to manipulate weight independently of mass and size.
The method of shrinking is described as "reducing the space between atoms." However, the suit's limiter is designed to prevent "sub-atomic shrinking," which wouldn't be possible by merely reducing the distance between atoms. It is possible though that the regulator is actually what causes the space between the atoms to shrink without shrinking the atoms as well.
(at around 1h 28 mins) When we see Scott Lang in a fight scene outside Darren's vault, he jumps onto a guard's gun. The ant man science says that when shrunk mass remains the same so the gun should fall down. But the story also includes the ability to manipulate weight independently of mass and size.
During the lamb-shrinking experiments the assistants are wearing all-over white suits as though in a completely "clean" environment. Unfortunately, they're wearing neither masks nor hair covering which renders the whole exercise pointless.
(at around 17 mins) After his daughter's birthday party, Scott is in his van. When the camera slowly moves to make a close-up of Scott, the reflection of the red light of the camera and a face (cameraman or assistant maybe) in the mirror of the van can be seen.
Around 1H18, when Dr Pym passed the metal check, we can see a white star on the tank. This tank is a T34-85 (Soviet tank of WWII) so the white star should not be on this tank as the Soviet tanks did not event display a red star on their turrets.
Only solution, Dr Pym used some of his leisure time with a brush to paint a star but this does not seem very plausible.

The San Quentin Correctional Facility is less than a 30 minute drive to San Francisco. The drive that Luis takes Scott on is not on the path to San Francisco but rather through some of the country side of Marin County, and a long way around to get to San Francisco. When you see the Golden Gate Bridge in the background as they are driving that area is referred to as the MARIN HEADLANDS, and is near a WWII fort facility.
Cassie, Ant Man's (Scott Lang) daughter is shown to be 5-6 years old in the film. Lang was sentenced to five years in prison and is shown getting out at the beginning. Assuming that he was arrested, convicted and sentenced when she was either in the womb or as a newborn, she would have 12-18 months old when he went to prison.
The film never explains how she got to know her father considering her very young age , especially when it makes it very clear that his ex-wife has not only moved onto another relationship, but is unhappy to see him at Cassie birthday party which occurs within days of his release from prison.
However, Scott spent only three years in prison, meaning Cassie would have been two or three years old when he was incarcerated (assuming she is five or six in the film). By age three, she certainly could have bonded with her father before his imprisonment.

During his presentation, Darren Cross shows footage of one of Captain America's raids against Hydra during WW II showing an Ant-Man and insinuating that it was Dr. Pym. If the Pym character is to be the same age as Michael Douglas, the character that played him, then there's no way that it could have been Pym in the footage because Michael Douglas was born in 1944.
