Other mistake: When Boss Baby drools on the file at Puppy Co. he is not nearly close enough for the drool to hit the file.
Other mistake: The creep tells us that this is the first issue, but mere seconds after the famous ending of Father's Day we see fan mail on the second page, impossible for the first issue. (00:21:05)
Other mistake: During the climax, when Junior reactivates the baby manufacturing machine, the first baby to emerge from the machine is naked. The machine's hands diaper this baby. However, when the other babies emerge from the machine they're already wearing diapers. (01:15:45 - 01:16:25)
Other mistake: At the end of the film, as Kenai walks up to Koda after he's been transformed back into a bear, Koda leaps on him in joy. If you look closely at Kenai's hind legs, there are a few frames of animation missing. His legs go from a standing to a sitting position instantly. It's barely noticeable (no pun intended).
Other mistake: When Fry and Colleen are lying in bed, his hand is around her shoulder but it is the same colour of Colleen's skin. (00:04:25)
Other mistake: After Mirabel places candles in front of everyone's door, she stops to look at the wall of photos which each depict members of the family standing in front of their respective doors. In the photos, you see each member of the family as a child in front of their door, but the door they're standing by depicts them as adults. When Antonio gets his door, the door shows him as a child.
Other mistake: When Tai is typing an e-mail of apology to Sora, he accidentally types "Love Tai" as opposed to "From Tai" which he finds more appropriate. At that moment, Kari walks in, resulting in Tai's embarrassed stumble into the keyboard. We then see a highlighted "From Tai" change into "Love Tai". It is possible that Tai had already changed it before we saw it and then accidentally pushed Ctrl+Z upon Kari's arrival, but this is more than doubtful.
Other mistake: There is a shot of a random newspaper blowing around in the middle of San Francisco. But the paper is from New York, with headlines about New York.
Other mistake: When Marry Anne flies into the dark forest for the first time she drops the boutonniere. After seeing the primrose petal she flies off empty handed but has the boutonniere later when she meets Roland.
Other mistake: When Riley and her parents arrive at their new home in San Francisco, several pieces of mail are sticking out of the mail slot in the door. A letter carrier would not deliver mail to a vacant house, let alone not push it all the way through the slot.
Other mistake: When showing "In Association with" in the English dub's credits, The Pokémon Company is misspelled as "The Pokeman Company." (01:15:37)
Other mistake: When Charles Darwin is on the plank, he is pushed into the water. Yet he is completely dry when he is back on the ship. (00:23:00)
Other mistake: At the beginning in England, Radcliffe tells the King of John Smith's death as they discuss war, and the King says they will await the return of John Rolf, indicating Rolf has already left England. It then cuts to the first scene with Pocahontas, which is before Rolf arrives in America, and the friend says that it is a long time since the news arrived of John Smith's death. There's no time for this news to have reached them.
Other mistake: When Gepetto paints Pinocchio's smile on, he uses a darker red. But the smile is in black.
Other mistake: In the "Peter and The Wolf" segment, Sasha the bird has a flesh-colored head. When he puts on his black cossack hat, the flesh areas of his cheeks and the flesh area between his eyes instantly turn black.
Other mistake: Constantine is driving along a road and an big rig truck is heading for him head on. The truck honks and they both hit the brakes, stopping just a foot away from each other. But at the speed the truck was moving it could not have possibly stopped so quickly. It would have skidded into Constantine's car. (00:35:00)
Other mistake: During the "Hellfire" sequence, when Frollo is singing "God have mercy on her, God have mercy on me...", his shadow against the wall behind him rises as he backs up closer to the wall. However, when he turns around to press against the wall, his shadow ends up far above his body when it should have become level with his body by that point - like the very next close-up shot of Frollo shows, which is itself a continuity error.
Other mistake: Throughout this, a running gag is that Fred can't drive stick/clutch. However, in "What's New, Scooby-Doo?" Series 2, Episode 6 "A Scooby-Doo Halloween," he yells at Shaggy that he's riding the clutch too hard at the beginning of the episode. If the Mystery Machine has a clutch mechanism, he would know how to drive stick/clutch.
Other mistake: At the start of the baseball game, the announcer says that the Gas House Gorillas are the visiting team, yet on the scoreboard they are shown above the Tea Totallers.
Other mistake: Everyone arrives on set at the same time but somehow Beast Boy goes and returns to the toilet within seconds.
Suggested correction: This is a case of cartoon logic at play, and therefore is not a mistake. Within seconds of Beast Boy going to and out of the bathroom most of the other Titans also somehow go in and do their thing and then leave the bathroom right after each other with no real time between. This is just part of the silly world of this cartoon.
