There are 2 sequels to Police story 3 (Supercop). This one which contains much action (Starring Michelle Khan) and another (police story 4 - First strike) which is more like a comedy, though with some great stunts (Starring Jackie Chan).. Once a Cop is an absolute action/FF. The plot isnt too intelligent, but if u are into the Police stories and a Michelle Khan fan, then u must see this one. (Cameo appearance by Jackie Chan dressed up like a women)
