If you like Jackie Chan and have never seen this film, you sould hurry to the video shop in your neiborhood right now. This is definitely the BEST in his early 70's.It was made with very cheap budget the same as his other 70's films made by Lo-Wei,so "Wodden Men" robots looks so shabby, even kids will find out that.But Jackie did his best in both acting and action on this. This film was shown in Japanese movie theatre soon after he became popular in Japan with "Drunken Master", and this movie is still popular in Japanese fans (so they said in many Japanese websites!!)
