Below average superhero movie in which a robust extraterrestrial takes on a crazy scientific
26 May 2013 | by ma-cortesSee all my reviews

Superhero Kronos , an alien, called "Supersonic Man," (a bodybuilder and former Tarzan , Richard Yesteran) is sent to Earth to decide the fate of mankind and thwart the schemes of evil men who would destroy the galaxy itself with their weapons from a distant galaxy . Supersonic is also given a human identity , Paul (Michael Coby or Antonio Cantafora) , a journalist who can change back to superhero by activating a watch device . But a nutty mad doctor named Gulik (Cameron Mitchell), supported by his hoodlums (Frank Braña, Luis Barboo), has evil plans , as he wants to rule the planet and abduct Patricia (Diana Polakov) , an eminent scientific (Jose Maria Caffarel)'s daughter and Supersonic's love interest . At the end our hero , Supersonic , enters the underground lair of the villain and has to pass through some corridors where he is shot, frozen, and burnt.

This is a humdrum adaptation based on Superman movies from a screenplay by the same filmmaker , Juan Piquer Simón ; as the plot lifts some scene from the script of Superman by Richard Donner . This is a pretty entertaining superhero movie though packs absurd situations and cheesy frames . Supersonic man and his human alter ego Paul were not played by the same actor , he was played by a Spanish and Italian actor respectively . As Supersonic was played by bodybuilder and former Tarzan José Luis Ayestarán , Paul, his human alter ego , was played by Antonio Cantafora . Atmospheric as well as ridiculous super hero movie contains bemusing scenes when appears the bouncing He man and takes place his confrontation to nasty hoodlums in some lousily made scenes , including primitive special effects . Part of the spaceship in the opening scenes is made from a Cylon Raider model and other parts have numerous "older technique" FX such as transparency , matte paintings, rubber-suited enemies , reverse-footage to create certain images ; all of them were made by Emilio Ruiz Del Rio , Francisco Prosper and the same director , Juan Piquer . As this superhero possesses mighty powers such as flying , sensational strength , throwing fire and transforming handguns into bananas , all of them being recreated by means of traditional effects . You will watch it and think it is either awful , hilarious, a masterpiece, or all three . It's a slight fun with embarrassing images , naive special effects , horrible musical score with awful songs by Gino Pecuri , campy set decoration and below average art direction . Although critics do not appreciate much this picture ; however has a kind of loopy, Ed Wood quality that must be endured to be totally considered . The fable is sometimes silly and laughable , though a few naif effects and action are professionally made . Some illogical parts in the argument are more than compensated for the excitement provided by Sonic man though some flying scenes are a little bit cheesy . While not a hit during its original run, the film became a limited success when reissued nearly 30 years later deemed to be one of the best worst films of cinema history .

The motion picture was lousily directed by Juan Piquer . Juan , who goes by "J.P. Simon" on foreign releases , began in films as a writer and assistant director and continued his career by making short films and documentaries . Juan has produced and directed "exploitation" pictures for two decades running . He was one of the main directors of the Spanish horror boom in the 70s and 80s specially for his quartet of horror films as ¨Escalofrio¨, ¨Slugs¨ , ¨Cthulhu Mansion¨ and his greatest success and immensely popular ¨Pieces¨ . Juan owns his own studio and created and/or designed many of the simple and primitive special effects sequences you see in any of his many imaginative undertakings . Piquer , who recently passed away, was a good craftsman who realized a lot of amusing as well as entertaining films . Juan Piquer who was director of the Mostra of Valencia (Spain) , displayed a professional career and specialized on all kind of genres as Terror , Sci-fi (The rift , The new Extraterrestres, Supersonic man) and made some adaptations about Jules Verne novels ("Fabulous Journey to the Center of the Earth" , "Mystery on Monster Island") . While his films have been universally panned by the prestigious reviewers, they have a kind of quality that must be endured to be utterly appreciated .
