Movie Man | 1960's Sci Fi TV Sound Effects @M0VIE | Uploaded April 2020 | Updated October 2024, 5 days ago.
So... I started watching lost in space and realized I heard that weird sound effect before. Well, I did some DEEP research and found a whole bunch of them from shows like Star Trek, Lost In Space, The Time Tunnel, The Twilight Zone, The Land of the Lost and so... SO much more.
