4. What Happened To The Submarine? - Fantastic Voyage (1966)
Fantastic Voyage is a fun little movie about a scientist named Jans Benes who develops a shrink ray, though he's almost assassinated and goes into a coma with a blood clot threatening to kill his brain. That's when a team of scientists decide to use the shrink ray to pilot a submarine into Bene's head and unclot the clot. There's a neat ticking clock aspect involved which means the team don't have very long to solve the issue, as the shrink ray will wear off and Jan Benes will be splattered all over the place. Luckily everything goes according to plan, and the team manage to escape from Benes' body just in time. The day looks to be saved, except for one minor issue: they left the freakin' submarine inside him! That's right: once the shrink ray wears off (as we
definitely, definitely know it will), Jan Benes is going to be reduced to a bloody splat on the walls. Nice job, team. What we haven't yet explained is that they also left a bad guy inside Benes, too - a man who will presumably return to his normal size as soon as the submarine does. Oh,
movies.
