Good question. There was
The Seventh Seal
that was the first film I saw that seemed completely devoted to an
aesthetic, but that was college. I'd have to say that the movie
Sorcerer
was the first one I saw that felt like there was something more going
on than just action adventure. There was a fetishizing of the scenery
and a mythic quality. I'd have to agree with Paul though about the Star
Wars flicks. The first time one of those massive ships cruised over
head with this overwhelming scale, I thought I might pee my pants.
