By looking at the title of this post and choosing to read on, you are, at the very least, open to the idea of a weird movie. This is an important step, I think. “Weird” is an abstract concept, one that for the purposes of this post means where what you’re seeing collides with your perception of reality. Think of the final minutes of 2001: A Spacey Odyssey or, more recently, the beginning and the end of The Tree of Life.
What makes us associate the weirdness with those examples more than, say, traditional Hollywood comedy? Comedy is rooted in expectation. When a situation defies our expectation of what we think should happen, we laugh. You don’t expect Brad Pitt to bite the bullet in Burn After Reading so quickly and brutally, so when he does it comes off as comical, but him walking on a beach with other lost souls in Tree of Life is just out there.
