A friend on another board has suggested that the interior of the spacecraft was actually the one designed for "This Island Earth", which was in production at the time "ICFOS" was released, according to the "2 1/2 years in the making" blurbs on the posters for "This Island Earth".

I can't really see enough of the "ICFOS" interior before the power runs out and it goes dark. Does anybody know -- one way or the other -- if there's anything to this intriguing idea?
