American reporter Larry Stanford (Peter Dyneley, 'Thunderbirds') has been globe-trotting for a while, and is currently working in Japan. He goes to interview a scientist, Dr. Robert Suzuki (Tetsu Nakamura, "Red Sun"), who almost immediately turns the hapless reporter into the latest guinea pig for his experiments in mutation. Soon, Larry has become a foul-tempered jerk who can't help but cave in to homicidal impulses here and there, as he slowly mutates. His concerned wife (Jane Hylton, "My Brother's Keeper") and friend / colleague (Norman Van Hawley, in his only film appearance) fret over his hostile behaviour.
A mad scientist / cautionary tale in the classic tradition, "The Manster" is delicious fun for people who love a good B flick. The sight of Larry in monstrous form (played by George Wyman ("Battle in Outer Space")) is a true hoot, as he runs around and slaughters people and baffles the police. Larry remains a very entertaining character, for even though he turns into this big jerk, he's not entirely unsympathetic. We know he's a victim of somebody else's machinations. That said, his tirades are often hilarious. The whole cast (including Jerry Ito ("Message from Space") as an obligatory police superintendent) does creditable if not exactly award-worthy work. The effects are a blast; especially cool is that scene where Larry notices an eyeball has appeared on his right shoulder. And that is when this movie really starts to cook. Terri Zimmern (another cast member here making the only feature film appearance of their career) supplies some sex appeal as the assistant to Suzuki who realizes that she has fallen for Larry. Nakamura is solid as the antagonist who is portrayed in an even-handed way: he does express regret late in the game.
If you are anything like this viewer and have a BIG soft spot in your heart for "monster on the loose" programmers, you too will likely find this to be highly engaging entertainment.
Seven out of 10.
