The giant, bald space alien is played by Michael Ross. He also can be spotted playing the bartender.
The film's poster was ranked #8 on "The 25 Best Movie Posters Ever" by "Premiere" magazine.
This film was made right after the success of "Sputnik", the Russian space satellite. The alien spacecraft is called a "satellite" because the writer thought that meant any spherical-shaped spacecraft.
The movie was shot in eight days for $89,000 (which was $10,000 under budget). This equates to about $820,000 in 2021.
Both of the film's leading ladies met with unfortunate ends. Allison Hayes died at the age of 46 due to lead poisoning from calcium pills she had been taking. Yvette Vickers' mummified body was discovered in her home in 2011. She was 82, and the evidence suggested that she'd died of natural causes over a year earlier.
