Note on the Title
A "double exposure" (or the less precise "multiple exposure") is the process by which film is exposed to light twice, creating on top of the originally exposed image a secondary one. Although not as common nowadays (and, indeed with digital, technically impossible although reproducible), if you've seen older movies, you've certainly come across it.
In this sense, as I belief in the value of rewatching films, of re-exposing myself to them (contrary to the legendary quip of Pauline Kael), I have decided to name this blog after art, as it were, to encourage double exposures—or multiple. I've certainly seen a number of movies more than twice. Double exposure sounds better though.
