the storyline of the stranger mirror somewhat the 1969 film journey to the far side of the sun ( make by gerry and sylvia anderson of thunderbird and space represent 1999 fame ) . a parallel universe earth be the premise of both film . but there be a difference . where the world in the stranger feature a totalitarian regime out to squash the freedom of the citizenry and journey to the far side of the sun merely show a true mirror world where handwriting and road and house and machinery of every kind and and of course internal organ be all in reverse ( or mirror ) order . so and the similarity of parallel earth be the only connection of both film . similarly and the tv series land of the giant come before both of those film and have run from 1968 to 1970. it feature a world that be nearly parallel to the earth with the exception that the planet be populate by giant 12 time the size of the human who crash land there . the idea of a totalitarian government out to capture and contain the little people be similar to the premise of the stranger more so than the premise of jttfsots . perhaps because of the similarly to lotg and a series to the stranger be shelve . have it turn into a tv series it would have be a sci fi version of the fugitive and with star glenn corbett be chase by the baddie from week to week and hide out in different location and etc . btw and a strong script could have help this film along .
