A respectable drive-in flick deserving of its long shelf life. Recommended only to fans of the B-movie genre, Phantom contains all the cheesy elements that make these movies so much fun.

There are a couple of inaccuracies in the title -- 1) for a Phantom, the creature manages to get spotted by everybody who even goes out on the water (all in the same rowboat, by the way; there must have been a 'No motors' sign posted for this ocean), and 2) the only way to go 10,000 Leagues under the ocean is horizontally, not vertically. As it is, this creature was always close enough to the surface to spot that unlucky rowboat every blinkin' time. People always screamed bloody murder whenever that rowboat tipped over, too, as if they knew a monster was doing it. Usually, when I tip my canoe over, I just shout something unprintable here -- but from now on, I'll suspect the Phantom, and scream appropriately.

The sets in this movie show the sad lack of budget that AIP always handed their directors. Lots of ceiling to floor curtains in the background, even hiding the mad professor's Top, Top Secret Death Ray Project. The entire College of Oceanography set consisted of the outer secretary's office (where the professor always took off his suit coat to put on his lab coat), and the professor's locked inner lab (where he always promptly took off the lab coat he had just put on, and changed into his radiation suit, apparently to protect him from rads given off by the Top, Top Secret Death Ray behind the flimsy curtain. When leaving the lab, the professor dutifully put on the lab coat again to walk through the door to the outer office, where he once again changed to his suit coat. I'll bet that lab coat never had to be washed.)

The real bucks were spent on the set of the Professor's beach house, where three doors were required -- one to enter from the outside, one to the Professor's bedroom, and one to the bathroom for the obligatory hubba-hubba shower scene of the Professor's daughter, Lois.

Lois is a bright spot in this picture. Not only does she take showers, but she also falls in love with the dashing scientist-turned-federal investigator, Ted Stevens. Lois listens to a lot of Ted's investigator stuff, and a whole lot of her father's mad scientist deathless dialogue (boy, can that guy mangle metaphors!). But mostly, Lois lounges. She lounges in the cabana chairs in front of her home, and she manages to be the only lounger on a totally deserted beach, but still gets stepped on by Investigator Ted, who happens to be looking the other way, where he just saw the Phantom.

Lois must get pretty tired of listening to Dad, because she doesn't shed a whole lot of tears when Phantom and Daddy pieces come blasting out of the ocean at the climax. Probably, she's wondering how she can get Investigator Ted to go back down there with a tackle box of dynamite, too. Then it'll be no more listening to exposition, and back to the lounging for Lois. As long as she doesn't do it in that snakebit rowboat.

The Phantom from 10,000 Leagues gets a respectable B-Movie 4 out of 10.

(Some Spoilers) The US Government is concerned about the goings on off shore and on the beaches around the newly opened Collage of Oceanography founded by the renowned expert of nuclear psychics Prof.King, Michael Whalen.

With a number of boats sunk and five people killed, from radiation burns, the US Government sends two of it's operatives FBI agent Bill Grant, Rodney Bell, and famed oceanographer and author Dr. Ted Stevens, Kent Taylor, to find out just whats behind these deaths. Uknown to the US Government there's also a spy ring, from an unnamed country, also at work trying to get the information that Prof. King has come up with in his nuclear research that includes his assistant George Thomas,Philip Pine, and his sexy but not too bright, go-between Wanda, Helene Statnton.

Prof. King had discovered a uranium deposit under the sea just outside the collage and somehow activated it causing this radioactive sea monster to be created.Attacking people sailing off-shore it killed a number of them by capsizing their boats and then exposing them to it's deadly radioactive rays.

The Professor is trying to use his discovery to create a "Death Ray" that can be used by the US military but it seemed to have backfired and caused the deaths of a number of innocent people. Prof. King is also reluctant to destroy the underwater uranium deposit and his creation the creature.

Somewhat better then your average "Monster from the Deep" 1950's sci-fi movie with some good acting on the part of Kent Taylor Michael Whalen & Rodney Bell that lifts this bargain basement monster film up a few notches and makes it more then watchable.

Agent Grant gets Prof. Kings secretary Ethal Hall,Vivi Janiss, the keys to Prof. King's Lab. to find out if he had anything to do with the mysterious deaths off shore, one of which was Ethal's son. This leads to Ethal's murder by Prof. King's assistant and foreign espionage agent George Thomas. Later a freighter is sunk by the underwater uranium mine, when it sailed over it, killing all on deck.

The two spies George Thomas and Wanda are easily caught by the FBI in that their so unprofessional that you wondered who, or what country, would be crazy enough to use them in their espionage activities. Prof. King destroys his personal papers on his experiments so no one would be able to duplicate them and then sails out to sea to the underwater uranium deposit. It's there with a TNT loaded time-bomb Prof. King destroys the uranium mine the creature and himself in a huge underwater explosion.

Prof. King's daughter Lois, Kathy Downs, who at first refused to believe that her father could be responsible for these tragic deaths is shocked into reality with his own cataclysmic demise that prevented more lives from being lost due to his misplaced loyalty to science then to human life.

While this Science fiction story lacks any real sense of credibility and our monster-The Phantom disappoints due to a lack of action and a rather plain appearance, there's enough inherent strangeness and weirdness going on here to make this an intriguing watch to fans of cult movies - the science fiction variety. Seeing Kent Taylor and Philip Pine is a treat here as always and they , along with Cathy Downs and Michael Whelan do give competent performances. Recommended mainly to those with a lot of patience and a love for Grade-Z movies.
