when i saw that this film be be air on late night tv i initially decide to give it a miss . i be glad that i then start watch . yes the special effect be the same a gerry andersen puppet show . some of the actor or actress be from his other production and he obviously use the same composer later on and a the cheesy soundtrack could only have come from one of his production and and the plot be as slow a a wet weekend . get by all that and you have a film that show up intriguing possibility . be there a planet on the far side of the sun . be it a duplicate earth . be everything about it reverse and if so do they speak english in reverse . i love this dated sf if only for gerry wonderful model car and plane and building and spaceship . some of them be not so far fetch a they seem back then . and do you see the european space centre logo . very reminiscent of the euro logo of today . suspend belief and spend a couple of hour watch this and you will be glad you do .
