 In the 1962 USA release version, on the film soundtrack, in a scene  in the control room of the Kosmokrator rocket, we hear a music track  titled "In Outer Space" from _Destination Moon (1950)_ (qv) by  Leith Stevens (qv), and later in the movie, in the scenes of eerie  destruction of the Venusian city, we hear a music track titled  "Metaluna Catastrophe" from _This Island Earth (1955)_ (qv) by  Herman Stein (qv). Both of these uses of music were uncredited and  unlicensed, and unauthorized by the copyright holders.
