A simple but fun Jackie Chan martial arts adventure, helmed by Wei Lo. It's not a very remarkable film, but when you pit it against the myriad of Shaw Bros productions of that time there are some notable differences. One of the most notable ones is the use of outside locations rather than studio sets, which does give the film a different feel.
Main attraction (and no doubt the primary reason for the relative popularity of this film) is Chan's presence. It's the first time I see him collaborating with Wei Lo and while the result isn't too exceptional, it does make for an amusing martial arts spectacle, with a couple of dynamic and lengthy action sequences.
It lacks the inventive choreographies of someone like Yuen though, and I have no clue why they tried to copy the Star Wars soundtrack (which sounds absolutely ridiculous), but these are minor hiccups that don't really stand in the way of the overall enjoyment. Nothing too out of the ordinary, but if you're looking for decent martial arts filler, this is a prime choice.
