I only caught part of this film on as a late night movie on a multicultural TV channel. It doesn’t looked very dated, though the story is set as an Asian period piece. Definitely a comedy. A young, married doctor is somehow begrudgingly accepted into a society of “ninjas” (not sure exactly) and is given a mission. His superiors expect (and hope) he will fail, but somehow he manages to take out an entire group. He has a sweet relationship with his wife who is completely naive about his undercover operation. She arrives with some other women, bringing food (or things for a picnic), and the doctor must make mundane excuses about the courtyard of carnage. I’d love to see the whole thing as it was funny, while having good action.
