You're wrong. This is not a 4:3 pan & scan, it's a 16:9 crop (or custom pan & scan), which is something quite rare - anamorphic widescreen is the norm.
I am not wrong. You are obviously right that it is not a 4:3 pan & scan: it is a 16:9 pan & scan. Which is not rare. These are commonly generated for airing on HDTV channels, and are likely one of the few HD versions of the movie that the studio has lying around already.
