Revealing mistake: When William and Jack open the door, enter the room, and walk past the helium-filled balloons (tied to a chair about 4' away), the balloons remain immobile. Due to how light helium balloons are, just opening the door or breathing nearby would be enough to cause the balloons to move somewhat - if they were actually there. (00:16:00)
Continuity mistake: The bottle of beer on the bar in front of Everett disappears in one shot but re-appears. Also, depending on the camera's angle, Everett either has his right hand holding onto the edge of the bar or is below the bar (out of sight). (00:04:25 - 00:40:14)
Continuity mistake: Young Norma Jean is shown a photo of her father placed at the head of her bed. It has him facing right and there is a large white defect in the photo at the upper left corner. When the photo is "talking" to her in a succeeding scene, he is facing left, and the defect is on the upper right corner.
Continuity mistake: The orange feather toy that was in the cat bed with the cat when Sam got to the bookstore was not there a couple camera shifts later. (00:25:33 - 00:26:25)
Continuity mistake: The wall clock, after staying at around 10:12, jumps 4 minutes (to 10:16) in less than 20 seconds. (00:01:05)
Factual error: While playing soccer in the background, Ali's "credentials" were displayed across the screen. Under "Academics", Ali is listed as "MEMBER OF THE NATIONAL HONORS SOCIETY" - but "Honors" should be singular ("Honor"). It is also odd to state "All 'A' honor roll." With a GPA of 4.3, something to the effect of "Highest Honors with Distinction" would be more likely. [It is possible to receive a "B" in an Advanced Placement course yet have a GPA above 4.0.].

Continuity mistake: Riley puts the red hard-covered book and two others into the box, but puts the same books into the box when Gabby starts to help. (00:13:35)
Factual error: Pettis' calculation of the amount Connor needed to replace his asset was way off. He stated, "[Cornell] brought me about 250 [$250,000] a year. He had at least 20 more years of service. Subtract five years he might have spent in prison, so you owe me, what? Six point two million." Pettis was presented as intelligent, but a quick mental calculation of even the full 20 years at $250,000 would total only $5 million (not $6.2 - an odd sum). For 15 years, the total would be $3,750,000. (00:28:45)
Continuity mistake: Although Adeline has her mouth to the ground (eating grass), her head is suddenly upright and still in a few views of Kay or Terry. The most noticeable sudden change in Adeline's head being upright occurs right after Adam hugs her. (00:34:34 - 00:35:00)
