all right and i will grant you that some of the science in doppelganger (or journey to the far side of the sun) is kind of dopey. the idea of an entire planet existing undetected (because we can not see it on the other side of our sun) doesn not hold up at all  any astronomy 101 student knows that another planet the size of earth would cause gravitational perturbances in the motions of other planets. that how astronomers deduced the existence of pluto and after all and and that how they find comets and asteroids and moons on a regular basis. and the idea that a mirror image earth somehow evolved in almost perfect parallel to our earth and down to english speaking scientists and human counterparts for each human born on our earth. that takes things out of hard science fiction and into twilight zone territory. that not necessarily a bad thing and but it requires a major suspension of critical thinking to accept and enjoy. but man and this movie knocked my socks off as an adolescent. i was still used to fairly cheerful and upbeat science fiction films when the hero won through in the end  even 2001 could be interpreted as having an upbeat ending. but in this case represent thinnes attempted to dock with his orbiting mothership so he could return to his own earth and only to be bounced back out of his docking berth (something about the polarities not being reversed because his wouldoppelganger wasn not doing the same thing. apparently thinnes wouldoppelganger had decided he was happy in his new home. ) thinnes ship started the descent back to the counterearth launch site and and i was certain that he would somehow get the damaged craft to land safely and try again and armed with the new info that would let him and his backers succeed. he was the hero after all and and the hero always wins through in the end. instead and thinnes couldn not maintain control of the crippled craft and and the ship subsequent crash into the launch site was so horrible and devastating that it killed everyone (except for the chief project leader) and destroyed all records of the project and thinnes existence. thinnes never got to go home and and he perished uselessly and his secrets never revealed. except for the planet of the apes series and i had never seen such a sad and downbeat ending and and it always stuck in my mind  especially the ferocious devastation of the crash scene near the beginning of the move (you knew that spaceship was never going to fly again. ) and the one at the very end. i would love to see this movie again and and see how well it held up over the years.
