The Proteus?[Possible spoilers]
Possible spoilers:
Is it just me or was the ending to 'Fantastic Voyage' abrupt? Isn't the Proteus still stuck in that guy's brain at the end of the film? There's also the issue of the Proteus returning to its normal size after 59 minutes or so. I think there was a parody of 'Fantastic Voyage' on 'Eek! The Cat': In Eek's timeline, Ross Perot managed to become President of the United States and he gets a raisin jammed in his brain! Eek and his friends are put in a small vessel and reduced to microscopic size to remove the raisin. After removing it, Eek and his friends make it back to the macroworld, but the sub is still inside Perot's head. A giant lump that resembles the sub bulges out his head.
I wonder if the makers of 'Fantastic Voyage' thought about this before they subjected us to the abrupt ending?
