 The older (and no longer used) US televsion version was completely uncut (for  once) with the exception of the "breast" scene towards the end. In addition  to this it also featured a new 6 min "prologue"  (which was made by the  distributors) explaining Godzillas origin and how the aliens made the other  monsters to try to takeover the Earth (using clips from a ton of Godzilla  films). In this version the credits are listed differently as well. Towards  the mid 80s this version was no longer aired and when Paramount released  their newer tv/video version, it was cut down, featured a slightly different  credit intro, and no longer had the great 6 min prologue. Long time rumors  have it that the switch was supposedly an error (or overlook) that was never  fixed. All US current versions (on all formats) of this film are the cut down  one.
