The Karate Kid/Fridge

Original films:

 * Why does Daniel choose the Crane Stance and kick in the final round? As has already been noted, the move is obvious and nigh-impossible to execute. Simple: Due to the "Sweep the leg" thing, Daniel's left foot can no longer support his weight, but rather than throw in the towel, he gambles everything on a desperation move, the one move he actually has a chance of performing. And it works.

2010 film:

 * In the 2010 The Karate Kid remake, Cheng was particularly jealous of Dre and Mei Ying's relationship. Keep in mind of China's one child policy and how there is a shortage of girls in China. Mei Ying might be the only girl that Cheng had a chance to marry.
 * Also the scene where Dre falls asleep on Mr Han's lap and his following hesitation to put his hand on Dre's shoulder made a lot more sense when
 * Fridge Horror: What would have happened if, instead of Mr. Han, Dre's mom had tried to intervene when the other kids were beating him up? They probably would have murdered them both.
 * Fridge Brilliance/Fridge Hilarity: Dre asks Mei Ying to make a pinky swear. Notice that she looked offset when he holds out his pinky finger. It's because that's how you flip someone off in China.
 * This also gives Mei Ying's parents further reason to be pissed at Dre when he shows his pinky finger at the audition.
