My local Biglots had a big kung fu movies DVD sale out for $3, and these two are cream of the crop.

The Eight Diagram Pole Fighter (1983): Produced by Shaw Brothers, this movie always top the lists as one of best kung Fu movie ever made, and it deservingly earn that title.

The lead actor Gordon Liu who was also in Kill Bill: Volume 1&2 (2004) is an excellent actor and emotions run thru him in every fight scenes which are spectaculer. The video quality is top notch with colors popping from screen.

King Boxer (1972): Also from Shaw Brothers, this was an international sensation (including USA) when it was released in 1973. With pristine picture quality to match. Highly recommended.
