Continuity: In the scene where Clark and Sara are kissing there are 2 mistakes. The first is when she pulls off her top you see her briefly with her bra on and then when he is undoing her jeans she is wearing her top again. The second mistake is after he undoes her jeans they are kissing and her left bra strap falls off her shoulder, the camera angle changes and its back on her shoulder again and falls down again, then another new angle the bra strap is yet again back on her shoulder, it seems unusual someone would keep pulling her bra strap back up in that moment and they should have made sure it stayed of her shoulder if it wouldn't stay in place.

Continuity: When Kirstie Alley is having a breakdown on the news set, the arrangement of the yellow papers next to her changes between shots.
