this less know film star roy thinnes ( from tv invader ) be actually what i consider a lost gem . it be make at a time where the story be more important that the special effect ( though the effect be fairly good for it time ) . a scientist theorize that there be another world in earth orbit directly behind the sun . since the sun always block it from u we can never see it from earth . roy thinnes be select to go on a mission to get to this world . i do not want to tell the rest of the plot because it will give the rest of the movie away . let just say there be some real surprise . the movie be british and have that good british flavor of act that be in such tv series like the avenger .
