Kill, Panther, Kill
At some point someone behind the scenes must have said, “Look, I know that this is basically just a cops-and-robbers story that we’re telling here, but, being that this is a Kommissar X film, we should at least have a frogman shoot at Joe Walker with a harpoon gun.” And so at this point a frogman emerges from the river beside where Walker and Emily are talking and shoots at Walker with a harpoon gun. Walker overpowers the frogman and demands to know who sent him, but — in another turn of events that seems to have come from an entirely different movie — the frogman himself is harpooned by an unseen accomplice before he can answer. Rowland arrives on the scene, and the two trail the accomplices to a nearby gym, where the first of two pretty great fight scenes in Kill, Panther, Kill! takes place.
