I was a big fan of the original. Remake could be interesting.

from IGN.com:

IGN has been informed by a reliable source that Sony Pictures is developing a remake of The Karate Kid that will be produced by Will Smith's Overbook Entertainment and Jerry Weintraub. Weintraub also produced the 1984 film, starring Ralph Macchio and Pat Morita, and its three sequels.

We were also advised that Smith's son Jaden, 9, is attached to star in the remake. Jaden Christopher Syre Smith starred opposite his dad in last year's The Pursuit of Happyness, which was also released by Sony. We understand that this new Karate Kid is currently out to writers.

IGN didn't hear back from Weintraub's office or Smith's reps by time of publish, so until there's official confirmation consider this a rumor.
