When I saw this movie I was old enough to know that the plot was pure fiction...but somehow I thought there might be a chance. And I would be more than happy to be on the maiden voyage with Raquel Welch. And some real scientists who knew what they were doing so we wouldn't die horrible deaths.
I am more familiar with the cheesy semi-knockoff called Innerspace. I think this and Three Amigos are the only acceptable Martin Short movies. I also have a thing for 1980s Meg Ryan.
Is this anywhere near the Islets of Langerhans?
