“You aren’t gonna say you have a bad feeling about this, are you? I hate it when you say that.”
I’ve flown from one side of this galaxy to the other, and I’ve seen a lot of strange stuff, but I’ve never seen anything to make me believe that there’s one all-powerful Force controlling everything.
Since Star Wars is themed in a universe where The Force is an energy field created by all living things that surrounds and penetrates living beings and binds the galaxy together (I don’t care too much for the literal bacteria explanation), it isn’t too farfetched to think that everyone would get gut feelings about whats going on. Given the characters constant peril saying I Have A Bad Feeling About This makes a lot of sense even if it did become something of a running gag.
Not only is the line “I Have A Bad Feeling About This” in the Star Wars movies but it recurs in many LucasArts projects including Indiana Jones and the Monkey Island games.
