Big update in regards to how ten-year-old Jaden Smith (Will Smith's son that we're being force-fed as an actor) plans to defend himself against bullies by learning karate: Jackie Chan will teach him karate. From Entertainment Weekly:
Jaden Smith has found himself a mentor. Jackie Chan will take on Pat Morita's Mr. Miyagi role in Sony Pictures' remake of The Karate Kid. The movie stars 10-year old Smith (The Pursuit of Happyness), who is the son of Will Smith and Jada Pinkett Smith, and will be directed by Harold Zwart (The Pink Panther 2). Will's production company, Overbrook, will produce, and Jada has been rumored for the role of Jaden's mother in the film.
But wow, adding the director of Agent Cody Banks and wife of Will Smith? I didn't see that coming. If Smith wants to make it a double-awful with double-nepotism, let's just go for the triple--bring in the screenwriter who did Most Valuable Primate and cast some long-estranged uncle of Will Smith (or Mike Myers playing a long-estranged uncle of Will Smith).

Or could we use CGI to bring back some deceased relatives of Will Smith who he'd like to see one last time, dead-eyed in the audience of a martial arts tournament? It doesn't even matter anymore. The scene where Jackie Chan lets Jaden Smith out of a duffel bag to attack will probably be pretty solid though.
