Kung-Fu Hustle is funny as hell. I think it's funnier than Kung Pow but did love Kung Pow. Anyways, if you like Kung-Fu comedies like Kung Pow and Kung-Fu Hustle, here's a couple of old ones you should check out:
The Last Dragon- One-name kung fu wonder Taimak plays Leroy Green, a.k.a. Bruce Leroy, a humble student of kung fu who has achieved the highest level of skill, but hasn't yet found his inner master. Wandering through the streets of New York in a Chinese peasant outfit, he accidentally becomes the protector of nightclub hostess/video jockey Laura Charles (played by former Prince protÃ©gÃ© Vanity, who also costarred in the trash classic Action Jackson). She's being threatened by a height-challenged mobster who wants her to play his girlfriend's video (the girlfriend is something of a Cyndi Lauper look-alike, played by Broadway star Faith Prince). Meanwhile, a man who calls himself Sho'Nuff, the Shogun of Harlem, wants to kick Leroy's ass and prove himself the baddest kung fu master in town. Add to this Leroy's smart-mouthed brother Richie (who calls Leroy "the chocolate-covered yellow peril"), a dregs-of-Motown soundtrack (DeBarge is a high point), ninja battles, pseudo-Eastern philosophical babble, and a jaw-dropping club performance by Vanity, and you have a hilarious example of why we're all so very glad the '80s are over. This movie is funny as shit and a must own for all Kung-Fu fans.
Six-String Samurai- A mysterious and powerful hero of the classic kind, Buddy, who looks exactly like Buddy Holly, is as skilled with his guitar as he is with his samurai sword. Thrown together with a kid whom he saves in a spectacular battle, the two of them must now escape their enemies and reach "Lost Vegas," the rock 'n' roll capital of this future world. With 'Death' keep on trying to find him and kill him and the final battle sequence they fight each other to the death. Note* 'Death' looks exactly like Slash from Guns N' Roses. Another must own for all Kung-Fu movies fans.
