This strip was partly inspired by a recent re-watching of the “classic” film, Fantastic Voyage, and partly by the shrinking/embiggening ray in our own ‘Monsters, Inked‘ comic strip. As a sci-fi theme, shrinking or enlarging people and objects seems to have fallen into disrepute. With more widespread understanding of atoms and molecules amongst the populace, it’s difficult to create a serious treatment of the genre without introducing major plot holes. As such it’s usually relegated to comedy films, where it can still work well.
Ramius: …but I don't understand why you need my help. I'm a submarine captain, not a doctor!
Doctor: We've developed an amazing device that lets us put a submarine into a patient's body so that we can perform surgery from the inside.
Ramius: So you mean you've actually found a way to shrink a full sized submarine and its crew down to microscopic proportions?
Doctor: Erm… not quite. But now that you mention it…
Doctor: …perhaps shrinking the sub would have been a better option!
