I've read one review comparing the director's and theatrical cuts, by someone who saw the former at a test screening. Their complaint was much more about re-editing which they thought destroyed the rhythm of the film, rather than omitted material. I can't wait to see the real, actual film.

Caitlín mentioned the differences in pacing; I don't see how the film could have unfolded any differently. It's a relatively fast-moving story as it is, simply by virtue of its structure as a mystery, and I think anything more obviously quick-cut would have ruined the city's sense of dreamlike time, that circles endlessly, but goes nowhere.
