Didn't have time to whip up a proper Hip-Hop Friday for everyone, but below you'll find an awesome youtube video that's compiled all the classic Wu Tang samples taken from the original kung fu flicks.
Special bonus: here are some links to torrents of my favorite Wu Tang sampled films
FIVE DEADLY VENOMS
SHAOLIN VS. WU-TANG
TEN TIGERS OF KWANGTUNG
Also, here's a link to an interview with the RZA where he discusses some of the samples.
Check that here.
