Other mistake: Beast Boy and Wildebeest fight in a cage suspended in an endless room, with no solid ground underneath. But during the fight both combatants keep stepping onto the gaps formed by the cage bars without their feet falling through, as if the cage bars on the bottom side are merely painted onto a solid surface. For instance, watch Beast Boy's feet when he turns into a skunk.
Other mistake: Kenneth Cope had to wear a toupee for his part. He did so, only it was initially on the wrong way, though no one pointed it out or noticed. If it ain't broke...
The Legend of the Lost - S2-E4
Other mistake: When the bad guy at the start of the episode runs to chase Sydney and Nigel, his foot kicks the side of the large stone lid which cause it to lift up. If this large piece of stone was real stone it would not have moved at all from being nudged by a foot.
Other mistake: When Harold goes to kill his father, we see his dad on the seat moving each time we hear the hammer, but if you look at his head, you don't see anyone hitting him at all.
Pool Party - S1-E2
Other mistake: After Cleo transforms into a mermaid, her wetsuit doesn't disappear for some reason.
Other mistake: When Cooper is on the floor after being shot, as he's signing the check, he is doing so with the pen closed, and proceeds to click it open as he hands it back to the room service.
Other mistake: When Michael walks into his office and sees Shawn, Michael is wearing a wedding ring. Looks like he forgot to take it off prior to shooting the scene. (01:00:00)
Doug and the Weird Kids / Doug's Behind The Wheel - S3-E6
Other mistake: Doug's Behind the Wheel: When Judy parallel parks the car, as Doug tells her that she just parallel parked, he sticks his hand right through her seatbelt to touch her shoulder. (00:21:51)
Injustice For All (2) - S1-E19
Other mistake: Unless he escaped prison, it makes no sense for Copperhead to be in the police van with the other Secret Society members. You can see him sitting there across from Solomon Grundy and The Shade.
Other mistake: At the end of the intro, before the logo appears you can see Mojo Jojo's brain. His brain is green and it should be pink.
Other mistake: In the English dub of the series, Tai's last name is Kamiya; however, when he makes reference to the family name plate his father put on the front door in this episode, the name displayed is Yagami. (00:03:00)
Other mistake: In the scene where Barca is bleeding at the pool, Batiatus comes and grabs his hair. Barca abruptly moves before Batiatus starts to actually pull his hair.
Other mistake: We see the letter about Merlin being written with a quill. However, despite the length of the letter being written we never see the quill being re-inked. (00:08:20)
Other mistake: When Viper slides the swords to Jackie and they come to a rest next to him, there is a small paper spider right beside Jackie. The only paper spider in the room, however, is Origami himself, and he is actually too far away at that moment and too big to fit the bill. Guess some of the animators got their depth perception messed up.
Other mistake: After Starfire burns the guy in the room everything is burned but the picture, magically.
Other mistake: Throughout season 1: The emergency workers are sometimes seen wearing a black jacket with an English spelling mistake on it. It reads "FIRE EMS RESOUE." Obviously the last word should be "RESCUE."
Farnsby & B - S1-E18
Other mistake: The ghost in the Farnsby's house knew Ronald Reagan as an actor but in 70 years she didn't know he was elected President even though she would have heard about it from people who lived in the house during his terms.
Other mistake: Duke is checking old copies of the Haven Herald around the time of Lucy (27 years ago). A headline on the one he's reading is about Lucy's disappearance. A moment later, he's reading a story about a meteor shower that occurs every 27 years; but the text we can see states that it just happened, and refers to dates in 2010 (having just happened, not '27 years from now'). This paper is supposed to be a 1983 edition. Also there is fake Latin 'filler text' printed in some columns.
Suggested correction: Lucy's disappearance is at the top of the newspaper and the hunter storm is at the bottom of the same page. Also, the paper predicts the next storm to occur. Just like how we know when to expect the next lunar eclipse or the next meteor shower, so I don't see how this is a mistake.
It's not a prediction of events to come, it's an article telling about the recent event, which states it was seen on the morning of the October 21, 2010. It even compares the 2010 shower to a previous shower that occurred in 2009. The mistake is valid.
Other mistake: In the last episode of season 3, Helen Cutter goes to site 333 to kill off the first hominids. Connor mentions that that's the site where thirteen members of a hominid family all died at once, and no one could ever figure out why. The implication is that it was Helen's actions that killed them off, and we see her doing it. Right after killing them, Helen herself is killed by a velociraptor, which also dies. Danny Quinn leaves their bodies there and walks away. Doesn't that mean that, when site 333 is discovered in the future, they would also find Helen's bones and those of the raptor? I imagine it would cause some confusion if the bones of a modern human and a velociraptor were found in the same strata and the same age as the earliest proto humans.
Other mistake: When Vincent is talking to Father about going to the masquerade party, you can see that both of his hands have fur and claws, but when he puts his hand on Father's shoulder and says "Don't worry", his hand is normal.
