Il pianeta fantasma

Low budget production but the script is visionary in regards to anti-gravity and magnetic fields. Nuclear physicist Robert Lazar who worked at Area 51 in Nevada during the 1990s, says his job was to back-engineer a spacecraft that apparently used anti-gravity for propulsion. While, he and other scientists could theorize about anti-gravity, they and nobody else had the knowledge to create or utilize such.

Also, magnetic walls have long been studied and attempted by U.S. Department of Defense research scientists.

So, while it is easy to dismiss this film due to hokey characters and cliché love story, the script is visionary for a 1961 movie. There are many other sci-fi films far worse than this such as Santa Claus Conquers the Martians with Pia Zadora. If you want bad, this is not bad. However, it is good for low-budget films but it is not good in the context of big budget sci-fi films.
