I believe this movie was a 70's movie. There was a young girl who used to do her martial arts fighting with her long hair. It was either a very long braid or long ponytail. She may have played alongside Bruce Lee in a movie or on her own. Can't remember. It was so many eons ago but it was a BIG hit when it was out.! Can anyone help me with the name of this movie?
