In 1975, the Japanese tokusatsu shows Ultraman and Kamen Rider gained immense popularity in Hong Kong, which led the Shaw Brothers Studio to make The Super Inframan as an attempt to cash-in on the two shows. The movie was literally known in Mandarin as Chinese Superman (Chinese: 中国超人 Zhōngguó Chāorén), which is the reason why you see the Superman symbol on the film's poster.
The film's plot is pretty simple: Elzebub, an evil demon princess, threatens to conquer the Earth, so Lei Ma, a high-class officer at the high-tech Science Headquarters, becomes the bionic superhero known as the Inframan to defeat Elzebub before she rules Earth with an iron grip.
The film was released in the United States thanks to the help from Joseph Brenner, who also dubbed the movie into English. It was also released in an attempt to cash-in on the popularity of The Six Million Dollar Man on American network television at the time. The film was made available on DVD for the first time in 2004, being distributed in Hong Kong and Japan.
In 1988, South Korea came up with their own tokusatsu film, known as Sparkman. The film also contains some Super Robot themes added in the mix, making it look almost like Mighty Morphin' Power Rangers in the process.
Sparkman also had significant use of Scanimate/TRON-style animation that would also be akin to that of South Korean anime Video Ranger 007, which was derivative of Japan's Video Warrior Laserion.
I've never seen bits of Sparkman, but I think this looks much cooler than The Super Inframan, considering its use of Super Robot themes and TRON-style special effects.
