Ninja Death 1
There it is. "A Fred Olen Ray Film". Not according to his IMDb profile it ain't. Here's the next one:
Attack Force 'Nam
There it is again! "A Fred Olen Ray Film". Well they're almost right this time. I had trouble finding Attack Force 'Nam on IMDb, because it's not listed under that name(the original title is "Behind Enemy Lines." I've submitted the additional title.) But if you do a search for David Carradine and Mako, the three movies they made together were all released in 1986. Since the film is obviously not Kung Fu: The Movie, the copy writer just guessed that it was Armed Response. So while the description is correct, the cast and crew is from another movie. whoops.
I still have no idea why they attached him to Ninja Death 1...
