doppleganger and ( or journey to the far side of the sun a it be more commonly know ) be write ( with input by the late donald james ) and produce by gerry and sylvia anderson and best know for their supermarionation television show such a thunderbird . the international space agency eurosec discover the existence of a mysterious planet on the other side of the sun and and propose a manned flight be send there . the committee balk at the exhorbitant cost and and shelve the project . but when a security leak at the agency be discover and fear that the russian might get there first and the project get the green light . american astronaut glenn ross ( roy thinnes ) be team with british scientist john kane ( ian hendry ) . after week of gruelling training and the phoenix blast off and head for the unknown . three week later and their ship crash in what appear to be a bleak and mountainous landscape . ross survives and but kane be badly injure . a light be see move towards them . i will leave the synopsis here . until this point and the film have be grip and with excellent special effect ( by derek meddings ) and music by anderson resident composer barry gray ( why it have not be issue on c. d. be a mystery ) . but when ross and kane crash land and and we discover the secret of the alien world it be a duplicate of our own and everyone on it be the same and the only major difference be that thing be reverse it become less interesting and and end with a shatter anti climax . i think the cinema be the wrong place to do this idea and in fact gerry and sylvia later do something similar on their space represent 1999 show . ross risk ( and ultimately lose ) his life in an effort to return to earth his earth . but why . the new earth be so similar he might as well not have bother . roy thinnes have recently do the invader television series and and give a competent performance ( pity there weren not more scene like the one where he row with his wife ) . ian hendry be good a kane and but vanishes from the story too soon . several actor go on to appear in the anderson u. f. o. such a ed bishop and george sewell . blink and you will miss nicholas courtney ( the brigadier from dr. who in a tiny role ) . but the acting honour go to the late patrick wymark a jason webb and head of eurosec . the character be not far remove from sir john wilder and the one he play in a. t. v. the power game . webb be such a devious character he be marvellous to watch . herbert lom contribution ( a a spy with a camera hidden in a false eye ) amount to little more than a cameo . like i say and the special effect be marvellous and a be the set . so the film be worth watch and but do not expect very much to happen once the action move to the mirror planet . with a strong script and this could have be another planet of the ape or dare i say it 2001 represent a space odyssey . in anderson production and he make the future seem like a great place and an adventure playground where science be cool and everyone have swank car whose door open vertically and sexy woman and and absolutely no suggestion that anything be seriously wrong with the world . we be in the future now and people be still watch coronation street every other night . how disappointing . if a mirror earth really exist somewhere and one hop that be a good place than this one . if all the woman there look like lynn loring or loni von friedl and i will be on the next flight .
