Just watched the film Sketches of Frank Gehry, directed by Sydney Pollack. It was released theatrically earlier this year and now it is airing on PBS's AMERICAN EXPERIENCE and will probably re-air soon.
Like many docs, even though the filmmaking technique is not great, the subject makes it worth watching. Gehry turns out to be pretty much a normal guy, not the typical intellectual phony that many architects become. If you're a fan of architecture, or even of documentaries, I'd recommend the film.
