“Has anyone seen my record?”

宇宙快速船 (Uchū Kaisokusen), (featured in experiment #819) produced by Toei and starring Sonny Chiba. Very notable names! Very dull movie!

And the dullness ramps up in the last quarter of the film, what with all the padding made up of repeated dog-fighting shots and re-used footage from other films (World War III Breaks Out according to some sources), it’s enough to give a guy Roji Panty Complex, I tell 'ya.

As intimated in the MST3K episode, Space Chief really isn’t as interesting as Prince of Space, and the Classic Sci-Fi Movie blog might have an explanation for that:

Toei Studios’ 1961 super hero “Iron Sharp” (Space Chief in the English version), was a copy of Prince of Space, which Toei marketed in 1959. Prince of Space was himself a copy of Toho Studios’ serial hero, “Supa Jaiantsu” (Super Giant), who was himself a copy of Superman.

Well, that about wraps it up for Invasion of the Neptune Men.

MY RECORD!!!
