Whoever got the rights to "Mr. Moto" in 1965 did a decent job bringing back this odd character. Henry Silva did not need to have his eyes taped back to give a slanted look. Nor did they have to "Yellowize" him with makeup. What impressed me most about Mr. Silva's performance is that he did not succumb to a grossly characterized Asian accent. Heck, they barely mentioned him being Asian at all until he had to go in disguise as a Japanese ambassador. All these elements of how Mr. Silva (and the director) should show that his race is not always relevant.
While the script was not overly clever.. it was decent enough not to wallow into a parody of itself or the 007 franchise. They tried to make their own secret agent . I have to say, Donger (the former Nazi assassin) was rather brutal and straight forward. The pacing and plot are decent and entertaining enough.
What does bring the movie down for me is not allowing for the audience to unravel the mystery along with the main character. There are one too many times the film/script reveals too much. There are enough "Red Herrings' to keep one distracted,. Even so, We should have the story unravel as if we were solving the mystery along with Mr. Moto.
