i saw this age ago and have recently watch on video . normally i find comedy not worth watch twice and but innerspace still make me laugh even after all this time . martin short character jack putter be great . he be a wimpy nerd and perfect to be inject in the butt by the doc carry dennis quaid . i like the part where his face be change to the cowboy and back again . very funny . meg ryan be a bit of a pain in the butt ( no pun intend ) and tho i think she should have marry jack and he be the cuter one . dennis quaid be great in this movie also and even confine to a teeny tiny pod float around in martin inside . the inside the body sfx be cool . the scene where dennis have to escape the heart and plus the part where he get to see thru martin eye etc really make good effect . it make you wonder how you would feel if that happen to you and martin reaction be priceless . the bad guy provide plenty of comic relief and i like cowboy sleez and the big thug who faint every time he saw something horrible . the scene where martin hang off the back of the truck be rather cool . i recommend this flick to anyone who like sci fi and comedy and romance and action and adventure . because this movie have the lot . i give this flick positive .
