I don't know if it was Technicolor, but this movie was in bright colors, literally very colorful. Interesting rocket design, rudimentary science, and multi-national, multi-ethnic, multi-gender characters and crew. Otherwise typical of late 50's early 60's sci-fi. The acting wasn't bad bad, just kind of bad. There was even the hint of romance or at least a relationship connection. The special effects were what you would expect from the time - - - definitely not big budget but adequate enough to convey a true sense of curiosity and sci-fi, provided and given that there was the proper suspension of belief. All in all, lovably cheesy.
