I remember watching this great movie when I was younger, but I can't remember the title of it. It was about a ten year old boy who does karate. He was't very good at it until he was inspired by a girl he liked that was better than him in his karate class. She was also a year older than him. It was testing day and he was doing great. Jackie Chan was next to him guiding him through testing in his mind. The last part of the test was breaking a board. He failed and ended up breaking his arm. I also remember this part where the two of them were hanging out and when he was going to say bye to her, he kissed her. She didn't say anything and acted very shocked. That night the boy repeated the kiss in his head a hundred times thinking of whether it was the right or wrong thing to have done.
Does anybody know what the title of this movie is?
