my take represent hilarious oddity piece with imaginative special effect and an appeal cast . what a weird way to make a movie . and yet and what a fun and enjoyable film it be . innerspace be a highly enjoyable little film and with some fine nifty special effect and some hilarious performance by dennis quaid and meg ryan and martin short . not to mention joe dante wacky inventiveness in his direction make innerspace be fun film for a very fun love audience . quaid play tuck pendelton and a party animal of a scientist who volunteer to be shrink to microscopic size and inject to the inside of a lab test rabbit . thing get awry when a rival company wreck havoc in the lab and and one of his colleague be force to inject him to hypochondriac jack putter ( short ) instead . while try to find his way out of putter body and tuck change jack life and a he become his conscience . on their trail be victor eugene scrimshaw ( kevin mccarthy ) and his group who want this little science project for themselves . then on be a combination of various chase and wackiness and secret service . the movie take the plot of an old b movie and and bring it back to life and turn it to a fun and highly spirited sci fi comedy . it like richard fleischer classic the fantastic voyage and but it have it own unique idea and storyline to set it difference . dante keep all in fast pace and and doesn not keep u wait for something to happen . the character play by the lead be appeal and the script be fill with genuine laugh and with short give the most . innerspace be enjoyable entertainment and not to be take seriously . rating represent out of 5 .
