The Thing With Two Heads

Have you ever wondered why there aren't any movies that have gorillas with two heads escaping from labs, running sideways down the street and invading corner markets just to eat bananas with both mouths? Maybe you've been looking for a movie about a bigoted doctor that's contracted "terminal chest cancer" and needed to figure out a way that he could prolong his life, but you don't even know if one existed. Well, my friends, search no further - your prayers have been answered and your movie has been delivered - it's been here since 1972! The title of which you seek is The Thing with Two Heads, directed by Lee Frost, and starring Ray Milland and Rosey Grier as the titular character.
Overkill

Mike Delano (Steve Rally), a detective for the LAPD, refuses to let the Yakuza take over the west coast. While eating in a sushi restaurant, Mike and his partner witness the murder of the owner and his daughter when they won't pay protection money to a couple Japanese gangsters. Mike's partner gets killed during the investigation, and he gets informally teamed up with Akashi (John Nishio), a Tokyo cop to out for vengeance for slain family members who were killed in the restaurant. Akashi is used to dealing with the Yakuza in Japan, and shows Mike that he had been dealing with them in the wrong way. While the Yakuza are not afraid of death, they do respect the method of death, so Akashi quickly dispatches one of the thugs and marks him with the phoenix to send a message. Now they must battle the gang to earn their respect. Will the Yakuza kill of Mike and Akashi, or will Mike and Akashi collect all of the limbs of the gang to earn the respect they deserve - and stop them from taking over the whole west coast? Did we mention that this was directed by Ulli Lommel, the same guy that directed one of our least favorite movies "Cocaine Cowboys"? This should be interesting...
