Successful screenwriter Steve Oedekerk (Nothing to Lose, Nutty Professor, Ace Ventura 2, Bruce Almighty) takes the martial arts film "Tiger and Crane Fists" and transforms it into a goofy spoof. He inserts himself in the film as "The Chosen One," a lonely warrior who must defeat the evil Master Betty. And a fighting cow.
It's pure silly fun from beginning to end, with Oedekerk dubbing the lines to cliché dialogue or absurd nonsense (plus weird noises), adding obvious/seamless CGI and new footage. For me it's hilarious, but your laughter may vary.
Kudos for Kung Pow for introducing me to Mint Royale, using their cool song "From Rusholme With Love" as the theme song.
I highly recommend getting the DVD to check out the alternate audio version of the movie, along with some crazy deleted scenes.
Also, keep a lookout for the sequel, in which Oedekerk said last year is in development.
