Do not be fooled by the fact that Bruce Lee is on the cover of the box, Bruce does appear in the film but only for a couple of seconds, if you buy this DVD expecting another Lee classic I'm afraid you will be very disappointed. He did work on the film but only as a guide on the production side and rumour has it that the small bit of Bruce in the movie was filmed without his knowledge as he helped cast on set.
The film itself is average, not a bad kung fu movie but nowhere near Bruce Lee standard, hence the producers cashing in by exploiting Lee's image. I would recommend you save your money or spend it on a proper classic Bruce Lee film such as Way of the Dragon, Enter the Dragon or Fist of Fury.
