The first teaser for The Canyons, a Paul Schrader-Brett Easton Ellis collaboration, was nothing — static magic-hour shots of Los Angeles. The second Canyons teaser, out today, is about retro fiddling. The title, the teaser and the movie are ironic imitations of a trailer for a late ’60s Roger Corman or Sam Arkoff film. In other words, it’s still about nothing. Schrader used to make movies about the world he was living in, or had lived in. The Schrader stamp meant something.
