Any info on that kata at the beginning

I don't know if it's an actual form (kenpo name for kata) but it definently has elements of the form long form 4 in it and various self defeense technique it could just be something speakman put together himself for the movie

The Form scene at the opening credits is all Kenpo, but it is a compilation of a whole bunch of clips from different Kenpo forms and sets pieced together. Kenpoists will recogize various movies from Form 4, 6, finger set, and others.
