Buona Sera, Mr. Campbell: Part 1 - S7-E6
Revealing mistake: After the younger bad guy delivers Amanda the cast iron skillet with fried eggs, he turns to leave, and she hits him over the head with it, knocking him unconscious. She then escapes through the window and older bad guy runs after her, and she hides in the bushes. A moment later all clear, she runs the opposite direction and straight into younger bad guy, who has somehow miraculously 'recovered' from getting hit over the head with a cast iron skillet. (00:21:05 - 00:22:20)
Revealing mistake: Kyle tosses Amanda onto the bed and then pulls out a black dress from their closet and disrobes her. She is completely nude from the backside. However, in the next shot she is facing Kyle and you can see the tip of a strapless bra peeking out/. (00:35:10)
The Night the Lights Went Out at Melrose - S7-E13
Revealing mistake: At Melrose, Ryan tells Michael the whole block is out of power, but their whole pool area is well lit from the camera crew.
Revealing mistake: As the Swamp Boogie Queen is singing to the audience and when she drags Kyle's brother onto the floor, her mouth movements do not match the lyrics, especially the higher and deeper notes. (00:28:45 - 00:30:15)
Revealing mistake: When Lexi is sexing Tony in the Boudreaux, the size of the room changes between shots. From cozy, to bright and roomy.
