The result, called Film, was undoubtedly the strangest entry in the Keaton canon. I won't explain it to you—because I can't—but it has something to do with Bishop George Berkeley's philosophical idea, "esse est percipi" ("to be is to be perceived"), proposed in 1710, which I think means that there is no objective reality, only our perception of reality, and that apparently when we leave the room and stop perceiving it, reality dissolves back into the dew of our ideas.

You may decide otherwise.
Appropriately, the film was completely silent.
