when joe dante want to do a remake of fantastic voyage and i like the way he decide to make his version into a comedy . i be surprise to discover that this film wasn not too successful and because i believe innerspace be good solid entertainment and albeit daft . the story begin when lt tuck pendleton ( dennis quaid ) and an excellent pilot but an irresponsible hard drinker volunteer for a highly unusual experiment . he will be place inside a submersible pod and and with the use of two microchip and be miniaturise and inject into a laboratory rabbit ( call bug and what be it about joe dante and looney tune character anyway . ) . but just after tuck have be shrink and a group of silicon valley industrial spy break into the lab and and steal one of the microchip necessary to reverse the miniaturisation process . in desperation and one of the scientist ( ozzie ) run with the syringe tuck be in and and inject him into the body of jack putter ( martin short ) . jack be a stress out hypochondriac who be terrify of life and and learn that a shrunken human be be inside his body doesn not make him any less neurotic . with tuck and jack now have to depend on each other for survival and they team up with tuck ex girlfriend lydia maxwell ( meg ryan ) to recover the steal chip before tuck air supply run out . i must confess to be a sucker for these loser come out on top story and and this film be no exception . jack be a man who have nothing go for him in life and but with tuck urge him on and jack manages to find inner confidence he never know he have and take control of his life . both tuck and jack character go through change in this film . see the world through jack eye and tuck begin to reflect upon the mistake he have make in his life . his irresponsible behaviour and heavy drinking be responsible for lydia break up with him and and he wouldn not be in the situation he in now if he hadn not recklessly go through with this hare brain experiment . dennis quaid make a likable character a tuck and because although he be a wise guy and his pep talk to jack be quite inspiring and how you can learn to take control of your own destiny . martin short be also a likable hero a jack and although he do have a tendency to go over the top . although he be suppose to be neurotic and his antic can grate on you a little on occasion . some of his antic can be funny too and such a the crazy dance he do in tuck apartment and and yell i be possess when he first hear tuck voice inside his head . the different scrape they get into be quite exciting and such a jack hanging on for dear life at the back of a refrigerated truck ( although it be a little overlong ) . tuck battle with one of the spy inside jack body be very well do and and the method of kill him be quite innovative too . one of the funny scene be when tuck alters jack face to look like the cowboy ( robert picardo ) and someone who have come to buy the microchip off scrimshaw ( kevin mccarthy ) and the man responsible for steal the chip in the first place . the special fx for these scene be pretty amazing and and the look on everyone face during these transformation be priceless . the fx use for inside jack body be incredible and and be totally realistic . one of the best scene be when tuck be nearly pull into jack heart and and be very nail biting . another good scene be when tuck end up in lydia body through a kiss with jack and and see his unborn child in her womb . that be a very awe inspire scene and and be worthy of the same fascination that make fantastic voyage great . i believe this be a criminally underrated film . admittedly and it a hard film to swallow and with thing like alter jack face to look like someone else . how exactly could you do that . but this be a joe dante film and so you have to suspend disbelief a little . meg ryan isn not give enough to do and and it a pity her character couldn not have be give enough development . there be also a lot of thing happen in this film and and not everything be tie up like it should have be . the way innerspace end and there could have be a sequel and but so far it hasn not be follow up . with dennis quaid and meg ryan divorce that doesn not seem very likely now . still and quaid have get a brilliant rapport with short and and some ( if not all ) of the important matter be resolve . it an entertaining film and and you find yourself be pull along for the ride whether you like it or not . after gremlin and innerspace be my favourite joe dante film .
