Revealing mistake: When Josh is telling Drake that Mindy told him she loves him and when Josh slaps Drake near the end of the scene, it is really obvious that Josh is slapping air. His hand is at least 6 inches away from Drake's head and yet they play the sound effect for a slap.
The Joker Goes to School (1) - S1-E15
Revealing mistake: Batman drives out of the batcave alone. The first bit of stock footage of the car leaving the cave does indeed show him alone in the batmobile. But the very next stock shot of the car speeding down the dirt road shows us Robin sitting in the passenger seat. (00:05:25)
Revealing mistake: It is strange that the news coverage at the beginning of this episode is able to cover the story from all angles in such rapid succession: from the helicopter straight to the ground, then even a close-up of the goon atop the crystal mount Diamondhead traps him on.
Revealing mistake: Season 2, episode 2 "Virtu-Date": When Pim is jumping rope with the girl, she is building a card house. When she jumps you can see the tape holding it together.
Revealing mistake: When Lazare shows up to talk to Will, we see that his left hand has been cut off. When Lazare is about to leave, he has his hands at his sides, and we can see that both arms are the same length, but the left one should be shorter, because it has no hand.
Revealing mistake: A recycled shot from an earlier episode causes Bob to enter the room wearing one costume and then suddenly be wearing another when he turns to begin his scene with Dresden and co. (00:11:50)
Revealing mistake: We can see Ecliptor's zipper from behind - slightly revealing on Saban's part, considering Ecliptor is supposed to be an evil monster henchman of Astromena's.
Revealing mistake: In the scene when Amy and Linda sing "Deck the Halls", when Linda steps on Amy's foot, you can easily see that she doesn't actually step on it.
Revealing mistake: The flags on Tipton hotel you see almost every episode never move; they're animated.
Episode 70 - S4-E1
Revealing mistake: Toward the end of the episode, Bert receives an envelope with pictures of him and Danny at a motel with some women. As they look at photos, Bert hands Danny some photos. Danny crosses left. Bert turns stack of photos over and says there is a note. He reads note and turns photos back over afterwards. The backs of the photos are blank. Danny crosses right to Bert holding photos. You can see on the back of Danny's photos the note Bert just read from the other side of the room.
Revealing mistake: Anytime the kids are shown running through the backyard, it sounds very obvious they are running on a wooden set floor instead of real grass-covered ground.
Revealing mistake: When Abby and Jen are drinking on the dock, Abby suddenly falls into the ocean and drowns. Just as they show a close-up of Abby falling about to hit the water, you can tell it's a stunt person. Monica Keena is a fairly short actress, and the stunt person is noticably taller with longer legs. Also, Abby had been wearing a very decorated black and silver skirt while on the dock. But the person about to hit the water appears to be wearing dark clothing without any silver or glitter.
Revealing mistake: When he's attacked in Down Below, Dr. Franklin is shoved against a station bulkhead/wall that wobbles when he hits it. (00:15:30)
Revealing mistake: When Billy lies dead in the morgue and the President fixes his hair while saying, "That's better." we can see Billy's throat move as he swallows.
Valerie Hangs With the Cool Kids - S1-E9
Revealing mistake: In episode number 9 of the first season, "Valerie Hangs With the Cool Kids", Valerie receives a call from Juna saying that she is required at the studio for filming. She rushes there, and when she opens the white door to enter the studio, there is a plastic sign on the door saying, "The Comeback". Seeing as Valerie's Comeback show is not solely filmed in the same studio as "Room & Bored", it has to be advertising the real show with Lisa Kudrow, and therefore shouldn't be in shot. (00:22:05)
Revealing mistake: When Derek is training Isaac how to fight, Isaac is forced to repeat his approach many times, which results in him being smacked down by Derek. During certain shots, as Isaac is about to plummet to the ground, his hoisting wire can be seen. (00:12:35)
Star-Crossed - June 15, 1972 - S1-E3
Revealing mistake: Sam stares at himself in the mirror and takes out his wallet to determine who he's leaped into. But the "reflection" in the mirror lowers the wallet and looks back up before Sam does. (00:05:20)
Revealing mistake: In the scene in the kitchen, Lucille Bluth takes a bottle of "Bushmills" (a brand or Irish whiskey) out of a grocery bag during a scene in the episode; however the liquid inside is clear/transparent and obviously not whiskey.
Revealing mistake: After the flashback to when the girls first met Cece at The Brew, she looks at them through a window outside when she leaves. If you look closely at Cece's hair, you'll notice a green glow, revealing that she's on a green screen. This explains why the image of the girls through the window doesn't look quite right. Cece is also wearing a different dress.
Revealing mistake: When Robert grabs Scott's shirt, Scott hits the wall and it moves backwards about an inch showing that it's fake.
