Many of these old movies have multiple titles due to releases in different countries and for VHS rentals. The original title here is "The Yellow Killer". The USA release for VHS rentals was "Kung Fu - ry!". It was titled in UK as "From Bangkok with Orders to Kill". My copy has Italian credits but is dubbed in English. I always start my reviews with a description of the opening scene so the reader/viewer can confirm we are talking about the same movie.
After watching this once I know I will never watch it again. It is certainly an action drama movie and not a martial arts movie. The fights are fist fights and then the bad guys remember they can use hand guns about half way through. I rate it as below average and do not recommend it.
