According to the list of films attributed to him at his IMDb profile, Ho has directed at least 115 different releases, most of which contain the word "Ninja" as part of their primary or alternative titles (several titles also contain the word "Kickboxer"). The exact number of films directed and/or written by Ho is not known, even he is unsure on the subject and most of the films have been re-released under different names. A number of Ho's films were also later further re-edited by Joseph Lai into "NINJA MYTH", a collection of 32 one-hour "Television Specials" released by IFD.
