journey to the far side of the sun ( aka doppelganger ) be an entertaining and twilight zone style sci fi offering from gerry and sylvia anderson ( the team behind space represent 1999 and ufo and thunderbird and fireball xl 5 and others ) . in the film and roy thinnes ( of the invader tv show ) and ian hendry star a astronaut send on a flight to a planet which share an exact orbit of the earth and but on the opposite side of the sun while hence previously hide from view . a pushy european space flight director ( over act by the late patrick wymark ) get the flight fast track and after rigorous training and the astronaut be good to go . thus begin the best sequence in the film and the launch and flight and landing on the other earth . dazzle rocket miniature work ( by derek meddings ) and a dream like and elegant spaceflight ( somewhat reminiscent of the best moment of 2001 represent a space odyssey ) be easy highlight of the movie . the landing on the doppelganger earth be both excite and eerie . after this and the twilight zone aspect of the film kick in while with a plot lift almost whole from the classic tz episode and the parallel . that aside and the film be still solid sci fi and with some intriguing amirror world stuff to chew on ( backwards write and leave hand handshake and for example ) . less successful be the scene depict a mid 21st century earth while where all the men wear turtleneck and nehru jacket and all the woman wear mini skirt . some of the relationship with woman in the film be very non pc by today standard as well . and ( in the most consistent failing of most 20th century sci fi ) the computer and telephone and other hardware be all big and colorful and clunky ( right out of patrick mcgoohan the prisoner ) . no one foresee the digital microprocessor age . if one can accept these failing in foresight and the movie be very interesting and with a solid lead performance by thinnes a the troubled astronaut . and with a nice and 1960s or early 70 style nihilistic end . for fan of retro sci fi ( like myself ) this be a journey worth take .
